Only the flowers do not turn red every ten days, and this flower is always in the spring breeze. ” China rose Bonsai is known as the "Queen of Flowers", with beautiful colors, full flower shapes, and a long flowering period. If well cultivated, its blooming figure can be seen all year round. However, many flower enthusiasts say that potted china rose Bonsai are difficult to cultivate, either because they only grow leaves without flowering, or because they are prone to diseases and insects. In fact, as long as you understand the "temperament" of china rose Bonsai and master scientific breeding methods, it is not difficult to make your potted china rose Bonsai lush with branches and flowers. Today, Yuan Shuji will talk to you about the cultivation methods and precautions of potted china rose Bonsai, all of which are practical and easy for novice flower enthusiasts to learn.
1、 Choosing the right 'good seedlings' is half the battle for successful cultivation. To raise potted china rose Bonsai well, the first step is to choose the right seedlings. The quality of seedlings directly determines their subsequent growth status. If diseased or weak seedlings are selected from the beginning, no matter how much care is taken later, the effect will be greatly reduced.
? Types of seedlings: china rose Bonsai seedlings are mainly divided into cuttings and grafted seedlings. Cutting seedlings are directly cultivated by cutting china rose Bonsai branches, with self rooted roots, strong adaptability, early flowering, and stable genetic traits, suitable for beginners; Grafted seedlings are the grafting of excellent varieties of china rose Bonsai scions onto rootstocks. The rootstock is usually selected from the robust and disease resistant china rose Bonsai, so grafted seedlings grow more vigorously, have stronger disease resistance, and have a larger flowering rate. However, the price is relatively high and requires certain maintenance skills. Novice flower enthusiasts are advised to prioritize the use of cuttings for easier maintenance.
? Observe the root system status: When buying seedlings, try to choose seedlings with soil balls, so that the root system is less damaged and the seedlings slow down faster. If it is a bare rooted seedling, the root system should be carefully observed. A healthy root system should be white or light yellow, full and shiny, and have many fibrous roots; If the root system turns black or brown, or if the root system is dry and has no fibrous roots, do not buy such seedlings, as the survival rate is extremely low.
? Check the condition of branches and leaves: Healthy china rose Bonsai seedlings should have green and shiny branches and leaves, with stretched leaves and no yellowing, curling, spots or other phenomena. At the same time, it is necessary to check whether the branches are thick and whether the buds on the branches are full. Seedlings with full buds have a stronger ability to sprout new branches in the future. Also pay attention to checking the back of the leaves and the gaps between the branches for signs of pests and diseases, such as aphids, red spider mites, powdery mildew, etc. Once signs of pests and diseases are found, give up decisively.
? Choose the appropriate variety: There are many varieties of china rose Bonsai, and different varieties have different growth habits and flowering performance. Due to limited space, potted china rose Bonsai should choose varieties with compact plant shape, strong branching ability, and frequent flowering. For example, "Juice Balcony" has a short plant shape, suitable for balcony potted plants, with a fresh orange yellow color and a long flowering period; The "Sea God King Balcony" has a large flower shape, like a steamed bun, with pink and tender colors, and good disease resistance; There is also the 'canary', which has a large flowering volume, exquisite flower shape, and is resistant to pruning, making it very suitable for potted plants. Flower enthusiasts can choose suitable varieties according to their preferences and maintenance environment.
Evaluation: Seedling selection is the foundation of potted china rose Bonsai farming. Choosing the right healthy and suitable seedlings can make subsequent maintenance more efficient and greatly improve the success rate of farming.
.Secondly, prepare a good "nutrient soil" to ensure a strong and thriving root system.
china rose Bonsai are plants that prefer fertilizer and air permeability, and have high requirements for soil.
. The soil for potted china rose Bonsai is limited, and if the soil is compacted and poorly permeable, it can easily lead to root system hypoxia and decay; If the soil fertility is insufficient, it will also affect the growth and flowering of china rose Bonsai. So, it is crucial to prepare the soil well.
Mastering the core requirements of soil: china rose Bonsai are suitable for growing in slightly acidic soils that are loose, breathable, well drained, and rich in organic matter, with a pH value between 6.0-6.5 being optimal. Soil should not only retain water and nutrients, but also not accumulate water, which requires a reasonable combination of soil components.
? Classic soil ratio scheme: Based on years of maintenance experience, Yuan Shuji recommends a practical soil ratio: 4 parts humus (or peat soil)+3 parts garden soil+2 parts river sand (or perlite)+1 part decomposed organic fertilizer. Rotten leaf soil (peat soil) is rich in humus, which can provide sufficient nutrients and has a loose texture; The garden soil has good stability and contains certain minerals; River sand (perlite) can increase soil permeability and drainage, avoiding water accumulation; Mature organic fertilizers (such as sheep manure, chicken manure, compost, etc.) can slowly release nutrients and improve soil structure.
? Soil disinfection is essential: The prepared soil cannot be used directly, and must be disinfected to kill bacteria, insect eggs, and weed seeds in the soil, avoiding the occurrence of pests and diseases in subsequent china rose Bonsai.
. The disinfection method is very simple. Spread the soil out and expose it to sunlight for 2-3 days, then use ultraviolet radiation to kill bacteria; If it is cloudy and rainy, you can also spray soil with carbendazim solution, mix well, seal and let it sit for 1-2 days, and then air dry until it is dry before use.? Adjust soil according to the region: Soil properties vary in different regions, and appropriate adjustments should be made when mixing soil. For example, in the southern region, there is more rainfall and the soil tends to be acidic. When preparing soil, the proportion of rotten leaf soil can be reduced, the proportion of garden soil and river sand can be increased, and the soil's permeability and drainage can be improved; The climate in northern regions is dry and the soil tends to be alkaline. When preparing soil, it is necessary to increase the proportion of humus or peat soil, and a small amount of sulfur powder can be added to the soil to adjust its acidity and make it slightly acidic.
Evaluation: Good soil is the guarantee for the robust root system of china rose Bonsai. Scientific soil allocation and proper disinfection can create a good growth environment for china rose Bonsai and reduce many problems in subsequent maintenance.
.Third, control the "light", sufficient light is necessary to bloom the branches
china rose Bonsai are typical light loving plants, and "all things grow by the sun". Adequate light is crucial for the growth and flowering of china rose Bonsai.
. Due to insufficient light, china rose Bonsai are prone to overgrowth, with thin and weak branches, yellowish leaves, and few or no flowers.
? Ensure sufficient sunlight every day: Potted china rose Bonsai require at least 6 hours of direct sunlight every day. The longer the sunlight, the more complete the photosynthesis, the more nutrients accumulated, and the more vigorous the flowering. So, the placement of china rose Bonsai is crucial, preferably on a south facing balcony, windowsill, or sunny area in the courtyard, so that china rose Bonsai can receive sunlight all day long.
? Pay attention to appropriate shading in summer: Although china rose Bonsai prefer light, during high temperatures in summer, the sunlight is too strong, especially the strong light at noon, which can easily burn the leaves and petals of china rose Bonsai, causing the leaves to turn yellow, the edges to burn, and the flowers to wither prematurely. So, during summer noon (10am to 4pm), it is necessary to provide appropriate shade for china rose Bonsai. You can use a sunshade net to block some of the sunlight, or move china rose Bonsai to a place with sufficient scattered light to avoid direct sunlight. In other seasons, such as spring, autumn, and winter, light photography is relatively gentle, allowing china rose Bonsai to receive sunlight throughout the day.
? Regularly rotate the flowerpot: During the growth process of potted china rose Bonsai, they will tilt towards the direction of sufficient light, and over time, the plant shape will become skewed, affecting its appearance. So, it is necessary to rotate the flower pot regularly, every 10-15 days, so that the pot can receive even light in all directions, so that the china rose Bonsai plant can grow evenly and beautifully.
? Pay attention to lighting issues for indoor maintenance: Some flower enthusiasts can only maintain china rose Bonsai indoors due to limited conditions. But indoor lighting is usually insufficient, making it difficult to meet the china rose Bonsai's demand for light. In this case, it is advisable to place china rose Bonsai near windows and in areas with the best lighting. At the same time, supplementary lights can be used to supplement the lighting. Use supplementary lights to illuminate for 4-6 hours a day to simulate natural lighting and meet the growth needs of china rose Bonsai. However, the effect of fill lights is not as good as natural lighting, so it is recommended that flower lovers with conditions try to let china rose Bonsai receive natural lighting as much as possible.
Evaluation: Light is the "power source" for china rose Bonsai to bloom. Reasonable control of light is necessary to ensure sufficient light time and avoid strong light burns in order to make china rose Bonsai grow vigorously and bloom abundantly.
.Fourth, scientifically "watering and fertilizing" to accurately "add meals" to china rose Bonsai
Watering and fertilizing are the most critical and error prone aspects of potted china rose Bonsai maintenance.
. Watering too much can easily cause root rot, while watering too little can lead to drought; Excessive fertilization can burn roots, while insufficient fertilization can lead to fertilizer deficiency. Only by mastering scientific watering and fertilization methods can we accurately supplement water and nutrients for china rose Bonsai.
（1） Watering: "When it's dry, it's wet; when it's not dry, don't water."
? Follow watering principles: When watering potted china rose Bonsai, follow the principle of "when it's dry, it's wet; when it's not dry, don't water; when watering, it's done thoroughly. 'Seeing dryness' refers to observing the surface of the potting soil. When the surface of the potting soil is dry 2-3 centimeters below, watering can be done; 'Seeing dampness' refers to the condition where the soil in the pot is completely moist after watering until water flows out from the bottom of the pot. It is not advisable to only water half of the pot, otherwise the roots will not be able to absorb sufficient water.
? Adjust watering frequency according to the season: Different seasons have different temperatures and evaporation rates, so watering frequency should also be adjusted accordingly. Spring is the peak season for china rose Bonsai growth, with temperatures gradually rising and evaporation increasing. Generally, watering is done every 2-3 days; Summer is hot with the highest evaporation rate, so watering is required every day, especially in the morning or evening, to avoid watering during high temperatures at noon and prevent excessive water temperature from burning the roots; The temperature gradually decreases in autumn, and the evaporation rate decreases. The watering frequency can be appropriately reduced, and watering should be done every 3-5 days; Winter china rose Bonsai enter a dormant period, with slow growth and reduced water demand. Watering should be controlled, usually every 7-10 days, and watering should be done during warm midday.
? Pay attention to watering method: When watering, slowly water along the edge of the pot, let the water slowly penetrate the soil, and avoid directly watering the leaves and flowers of the plant, especially on rainy days or at night. Long term moisture on the leaves can easily cause diseases. If there is dust on the leaves, you can use a spray to spray clean water, but you must ensure that the leaves can be dry before the evening.
? Choose a suitable water source: It is best to water with rainwater or river water, which is rich in minerals and neutral or slightly acidic, suitable for china rose Bonsai growth. If using tap water, it is necessary to first air dry the water in sunlight for 1-2 days to allow the chlorine gas in the water to evaporate, while also increasing the water temperature to avoid cold water stimulating the roots.
(2) Fertilization: "Apply thin fertilizer frequently and supply according to demand"
? Clarify the fertilization principle: Fertilization of potted china rose Bonsai should follow the principle of "apply thin fertilizer frequently", that is, the concentration of each fertilization should be low, but the frequency of fertilization can be higher to avoid applying concentrated fertilizer at once, which may cause root burning.
. At the same time, the types and amounts of fertilizers should be adjusted according to the growth stage of china rose Bonsai to achieve on-demand supply.? Fertilization methods for different growth stages:
Growth period (March May in spring, September October in autumn): At this time, china rose Bonsai mainly grow branches and leaves, requiring nitrogen fertilizer as the main fertilizer to promote branch and leaf growth.
. You can apply decomposed thin cake fertilizer water every 10-15 days, or use nitrogen phosphorus potassium compound fertilizer diluted according to the instructions before application.Pregnancy period (May June in spring, October November in autumn): As the china rose Bonsai begins to develop flower buds, it is necessary to increase the use of phosphorus and potassium fertilizers, reduce nitrogen fertilizers, and promote bud development and flowering.
. Potassium dihydrogen phosphate solution can be applied every 7-10 days, and spray can be used to spray leaves and buds, or to irrigate roots, so that china rose Bonsai can blossom larger, brighter and longer.Flowering period (June August in summer, December February in winter): During the flowering period of china rose Bonsai, more nutrients are consumed, but excessive fertilization should not be applied at this time, otherwise it may cause the flowers to wither prematurely.
. You can apply a thin layer of fertilizer before the flowers bloom, stop fertilizing after flowering, and replenish nutrients after the flowers have withered. Dormancy period (December to February of the following year in winter): china rose Bonsai in northern regions enter deep dormancy, while china rose Bonsai in southern regions have less obvious dormancy. During the dormant period, the growth of china rose Bonsai almost stagnates and does not require fertilization. Otherwise, fertilizers cannot be absorbed and will accumulate in the soil, leading to root burning.? Choose the appropriate type of fertilizer: china rose Bonsai can be fertilized with a combination of organic and inorganic fertilizers. Organic fertilizers include decomposed cake fertilizers, sheep manure, chicken manure, bone meal, etc., with mild and long-lasting fertilizer effects, and can also improve soil structure; Inorganic fertilizers are chemical fertilizers, such as urea, potassium dihydrogen phosphate, compound fertilizers, etc. They have fast fertilizer effects, but attention should be paid to concentration. It is recommended to mainly use organic fertilizer in daily life, and to use inorganic fertilizer in combination during key growth stages (such as the bud stage) for better results.
? Fertilization precautions: Before fertilizing, loosen the soil to make it loose, which is beneficial for the root system to absorb fertilizer; When fertilizing, avoid direct contact with the roots and apply along the edge of the pot, then cover with a thin layer of soil; If the soil is dry after fertilization, water it once to promote fertilizer dissolution and absorption; Do not fertilize during rainy and hot weather. Fertilizers are prone to loss during rainy and hot weather, and can burn roots during high temperature.
Evaluation: Watering and fertilizing are the "energy supply stations" for the growth of china rose Bonsai. Scientific watering and fertilizing can provide sufficient water and nutrients for china rose Bonsai, which will not cause poor growth due to water shortage or fertilizer deficiency, nor will it cause problems due to excessive water and fertilizer concentration. It is the core link in nurturing china rose Bonsai.
.Fifth, timely "pruning" to shape beautiful plant types and promote multi flowering
Pruning is an essential part of potted china rose Bonsai maintenance. Reasonable pruning can not only shape beautiful plant types, but also reduce nutrient consumption, promote new branch germination, and make china rose Bonsai bloom more and better.
. Many flower lovers keep china rose Bonsai that do not bloom, largely due to poor pruning.
The best time for pruning: china rose Bonsai pruning is mainly divided into heavy pruning in winter and light pruning during the growth period.
Winter pruning (December February of the following year): At this time, china rose Bonsai enter a dormant period, and pruning causes the least damage to plants.
. The main purpose of winter pruning is to shape the plant shape, remove diseased and weak branches, cross branches, and overly dense branches, while retaining strong main branches, laying the foundation for growth and flowering in the following year. Light pruning during the growth period (spring autumn): Pruning during the growth period mainly includes post flowering pruning, thinning branches, and topping. Pruning after flowering should be carried out in a timely manner after the flowers have withered, to promote the germination of new branches and their subsequent flowering; Sparsing branches is the process of removing overly dense branches, increasing the ventilation and transparency of plants, and reducing pests and diseases; Topping is aimed at excessively long branches, cutting off the bud points at the top, controlling the height of the plant, and promoting branching.? Specific methods for winter pruning: Firstly, all diseased, dead, and weak branches on the plant should be pruned. These branches not only consume nutrients, but also are prone to breeding diseases and pests; Then, cut off the intersecting and overlapping branches to ensure ventilation and light transmission between them; Finally, the robust main branches that are retained are shortened, usually by 15-30 centimeters according to the size of the plant. Each main branch should have 2-3 full bud points facing outward, so that the newly sprouted branches will grow outward and the plant shape will be more stretched.
? Specific method for light pruning during the growth period:
Pruning after flowering: After the flower withers, cut from the 2-3 leaves under the flower, because the axillary buds of this leaf are relatively full and have a strong ability to sprout new branches.
. If the branches are thin and weak, you can cut more, starting from the 5-6 leaves under the flower; If the branches are strong, they can be pruned less to promote rapid sprouting of new branches.Pruning: If branches are found to be too dense during the growth period, they should be pruned in a timely manner, cutting off some inward and overly dense branches to allow ventilation and light to pass through the inside of the plant. Generally, there should be a 5-10 centimeter gap between branches. Topping: When the branches grow too high or excessively long, topping should be done by cutting 1-2 centimeters off the top, controlling the height of the branches, promoting lateral branch germination, and making the plant more compact. Topping is usually done in spring when new branches grow to 15-20 centimeters.
? Pruning tools and precautions: Sharp gardening scissors should be used for pruning. Before pruning, the scissors should be disinfected and wiped with a carbendazim solution to avoid spreading bacteria.
; When pruning, ensure that the incision is smooth and avoid tearing the branches; After pruning, apply plant ash or carbendazim ointment to the incision to prevent bacterial infection; Trimmed diseased branches and dead branches should be promptly cleaned out of the flowerpot, burned together, and not left in the flowerpot to prevent the growth of pests and diseases.Evaluation: Pruning is the "shaper" and "flower inducer" of potted china rose Bonsai. Reasonable pruning can make the china rose Bonsai plant look beautiful, concentrate nutrients on strong branches and flower buds, and achieve the goal of multiple and good flowers.
.Sixth, do a good job in "disease and pest control" to ensure the healthy growth of china rose Bonsai
china rose Bonsai are known as "medicine jars" because they are easily attacked by diseases and pests, such as powdery mildew, black spot disease, aphids, red spider mites, etc. These diseases and pests can seriously affect the growth and flowering of china rose Bonsai, and even lead to plant death.
. So, the prevention and control of pests and diseases must be based on "prevention first, combined with prevention and control".
? Common diseases and prevention methods:
Powdery mildew: mainly harms leaves, tender branches, and flower buds. In the early stage of the disease, white small powder spots will appear on the leaves, gradually expanding into white powder spots. In severe cases, the entire leaf will be covered by white powder, and the leaves will curl, turn yellow, and fall off. Prevention: Keep the plants well ventilated and transparent, and avoid overly dense branches and leaves; Timely cleaning of fallen leaves to reduce the growth of bacteria; Pay attention to drainage during the rainy season to avoid water accumulation in the soil. Prevention and treatment: In the early stage of the disease, spray the plants with a 600 fold solution of 75% Baijunqing wettable powder or a 1500 fold solution of 25% Fenxianning wettable powder, every 7-10 days, and spray continuously 2-3 times to achieve results. Black spot disease: This is one of the most common diseases of china rose Bonsai, mainly affecting the leaves. In the early stages of the disease, small brown spots appear on the leaves, gradually expanding into circular or irregular black spots. The edges of the disease spots are yellow, and in severe cases, a large number of leaves fall off, affecting plant photosynthesis. Prevention: timely cleaning of diseased and fallen leaves, and centralized burning; Avoid keeping the leaves moist for a long time and do not water them when watering; Regularly spray protective fungicides on plants, such as Bordeaux mixture. Prevention and treatment: In the early stages of the disease, spray 50% carbendazim wettable powder at 500 times dilution or 70% methyl tobramycin wettable powder at 800 times dilution every 7 days for 3-4 consecutive times to effectively control the condition.
Root rot disease: It is often caused by soil waterlogging and poor soil permeability, and mainly harms the root system.
. In the early stage of the disease, the leaves of the plant turn yellow and wither, and the growth is slow. In the later stage, the root system rots and turns black, with a strange smell. In severe cases, the entire plant may die. Prevention: Choose loose and breathable soil, and place a layer of ceramic particles or crushed stones at the bottom of the flowerpot to enhance drainage; Watering should follow the principle of "seeing dry and seeing wet" to avoid water accumulation; Regularly loosen the soil to improve its permeability. Prevention and control: If symptoms of root rot are found in the plant, immediately remove the pot, rinse the roots with clean water, cut off the rotten roots, then soak the roots in carbendazim solution for 10-15 minutes, remove and air dry, and replant in disinfected soil. After planting, place in a cool and ventilated place to slow down the seedlings.? Common pests and control methods:
Aphids: Aphids are small in size and often gather on tender shoots, leaves, and flower buds of china rose Bonsai. They feed on sap, causing leaves to curl and deform, flower buds to fall off, and can also spread viral diseases.
. Prevention: Regularly inspect plants, especially tender shoots and the back of leaves; Timely remove weeds around the flowerpot to reduce aphid breeding grounds. Prevention and control: When the number of aphids is small, they can be manually brushed off with a brush dipped in water or rinsed with clean water; When the quantity is large, spray 10% imidacloprid wettable powder at 1500 times dilution or 50% imidacloprid wettable powder at 2000 times dilution, every 5-7 days for 2-3 consecutive sprays.Red spider: Red spider has a small body size and mainly inhabits the back of leaves. It feeds on leaf sap, causing yellow white spots to appear on the leaves, gradually expanding into gray white. The leaves lose their luster and eventually fall off.
. Red spider mites reproduce quickly, especially in high temperature and dry environments where they are prone to outbreaks. Prevention: Keep the environment moist, regularly spray water around the plants to reduce temperature and humidity; Regularly inspect the back of the leaves to detect pests in a timely manner. Prevention and control: After discovering red spider mites, spray them with 20% imidacloprid emulsion at 1500 times dilution or 40% trichlorfon emulsion at 1000 times dilution, with a focus on spraying the back of the leaves. Spray every 7 days for 2-3 consecutive times, and pay attention to alternating medication to avoid red spider mites developing drug resistance.Thrips: Thrips mainly harm the flowers and tender leaves of china rose Bonsai. After sucking juice, the flowers become deformed and fade, and the tender leaves curl and turn green.
. Thrips are small in size, agile in movement, and difficult to detect. Prevention: Regularly clean the dead branches and leaves around the flowerpot to destroy the habitat of thrips; Spray preventive insecticides before the china rose Bonsai bloom. Prevention and control: In the event of thrips infestation, spray 25% thiamethoxam water dispersible granules at a dilution of 2000 times or 10% imidacloprid water at a dilution of 3000 times every 5-7 days, continuously spraying 2-3 times. At the same time, spray the ground around the flowerpot to prevent thrips from escaping.Evaluation: The prevention and control of pests and diseases should adhere to the principle of "prevention first, combined prevention and control". Daily maintenance and management should be done well, and plants should be kept ventilated and transparent, which can effectively reduce the occurrence of pests and diseases.
; Once pests and diseases are discovered, timely measures should be taken to prevent the spread of the disease and ensure the healthy growth of china rose Bonsai.7. Timely "repotting" to provide sufficient growth space for china rose Bonsai
The root system of potted china rose Bonsai will continue to expand as they grow, and the space in the pot will be limited, leading to a gradual decline in soil fertility. Therefore, timely repotting is very important.
. Changing pots can provide more growth space and fresh soil for china rose Bonsai, promote root growth, and make plants stronger.
? Determine the time for repotting: The best time for repotting is from March to April in spring, when china rose Bonsai have just finished dormancy and begun to sprout new branches. repotting causes the least damage to plants and slows down seedlings quickly. Secondly, from September to October in autumn, the growth rate of china rose Bonsai slows down, and even after changing pots, they can smoothly slow down the seedlings. Avoid changing pots during high temperatures in summer and low temperatures in winter. High temperatures in summer can easily cause dehydration of plants, while low temperatures in winter can affect root recovery.
? Choose a suitable flowerpot: When changing pots, the flowerpot should be one size larger than the original pot. The material of the flowerpot should be ceramic or purple clay pots with good breathability, and avoid using plastic pots (poor breathability) and ceramic pots (heavy and poor breathability). The bottom of the flowerpot must have drainage holes to prevent water accumulation and root rot.
? Preparation before changing pots: 1-2 days before changing pots, water the china rose Bonsai once to make the soil moist and facilitate the removal of pots; Prepare new soil (prepare according to the previously introduced soil ratio and disinfect it properly); Clean the new flowerpot thoroughly and place a layer of ceramic particles or crushed stones at the bottom of the pot to enhance drainage.
? Specific steps for changing pots:
Remove the pot: Take out the china rose Bonsai from the original pot, hold the base of the plant with one hand, and tap the side wall of the pot with the other hand to separate the soil from the pot. Then gently pull out the plant, being careful not to damage the roots. Root repair: Gently shake off the soil at the roots of the plant, inspect the roots, cut off rotten, blackened, and withered roots, as well as excessively long fibrous roots, and retain healthy main and fibrous roots. After trimming, soak the roots in a carbendazim solution for 5-10 minutes to disinfect and kill bacteria.
Top the pot: Spread a thin layer of soil at the bottom of the new pot, place china rose Bonsai in the center of the pot, adjust the height of the plant to allow the roots to naturally stretch, then fill the pot with soil, gently tapping the pot while filling to tightly bond the soil with the roots. Fill the soil 2-3 centimeters away from the pot mouth, do not fill it too full, it is convenient for watering.
.Slow down seedlings: Immediately water the china rose Bonsai once after potting, then place it in a cool and ventilated place to slow down seedlings. During the slow down period, avoid direct sunlight and keep the environment moist. After about 1-2 weeks, the plant begins to sprout new leaves, indicating successful slow down seedlings. At this time, the china rose Bonsai can be moved to a sunny place for normal maintenance.
.Evaluation: Timely repotting can provide a good growth environment for china rose Bonsai, promote root regeneration and growth, and avoid poor plant growth caused by small flower pots and soil compaction. It is an indispensable part of potted china rose Bonsai maintenance.
.Eighth, do a good job of "winter management" to ensure the safe winter of china rose Bonsai
Although china rose Bonsai have a certain degree of cold resistance, the root system of potted china rose Bonsai in pots is easily affected by low temperatures. Therefore, winter management should be done well to ensure the safe winter of china rose Bonsai.
.
? Adjust wintering methods according to regions:
Northern regions (temperatures below -10 ℃): Winter in the north is cold, and potted china rose Bonsai need to be moved indoors for wintering. Before the frost falls, move the china rose Bonsai indoors to a sunny place and keep the room temperature between 0-5 ℃, not higher than 10 ℃. Otherwise, the china rose Bonsai will sprout new branches ahead of time, consume nutrients, and affect the flowering of the following year. During indoor overwintering, watering should be controlled to keep the soil slightly moist and avoid excessive watering that can cause root rot; Wipe the leaves with clean water every 10-15 days to keep them clean. Southern region (temperature above -5 ℃): The winter climate in the south is relatively mild, and potted china rose Bonsai can overwinter outdoors. But pay attention to cold prevention, wrap a layer of straw or plastic cloth around the flowerpot to protect the roots from freezing; Place china rose Bonsai in a place with the wind away from them and facing the sun, avoiding direct cold winds; Reduce watering and keep the soil dry. Dry soil is more resistant to cold.
? Preparation before overwintering:
Pruning: Trim once before overwintering, cutting off diseased branches, dead branches, weak branches, and excessively long branches to reduce nutrient consumption and improve the plant's cold resistance.
. Fertilization: In the autumn months of October and November, apply a decomposed organic fertilizer (such as sheep manure or chicken manure) to china rose Bonsai to increase soil fertility, store nutrients for plants, and improve cold resistance. After fertilization, do not water again and allow the fertilizer to slowly release.Cleaning: Clean up fallen leaves and weeds around the flowerpot, burn them in a concentrated manner, reduce the breeding grounds for pests and diseases, and avoid pests and diseases lurking in winter, which may harm the plants in the coming year.
.? Precautions during wintering:
Avoid direct sunlight: For china rose Bonsai that overwinter indoors in the north, although they should be placed in sunny places, they should be appropriately shaded during strong winter sunlight to avoid burning their leaves.
.Preventing stuffiness: When overwintering indoors, it is important to maintain ventilation and avoid excessively hot and humid conditions, as this can easily lead to diseases.
.Do not leave the room too early: After the temperature rises in spring, do not rush to move the china rose Bonsai outdoors. Wait until the temperature stabilizes above 10 ℃ and there is no late spring cold before moving them outdoors to avoid damage to the plants from low temperatures.
.Evaluation: Winter is the dormant period of china rose Bonsai. Proper overwintering management can help china rose Bonsai accumulate nutrients, enhance their cold resistance, safely pass through winter, and prepare for the emergence of new branches and flowering in the following spring.
.9. Frequently Asked Questions to Solve Your Maintenance Confusion
During the maintenance process of potted china rose Bonsai, flower enthusiasts often encounter various problems. Below, Yuan Shuji will answer a few common questions to help everyone solve their maintenance confusion.
.
Question 1: What if china rose Bonsai only grow leaves and do not bloom?
Reason: There are three main reasons. Firstly, there is insufficient light. china rose Bonsai prefer light, and insufficient light can cause plants to grow excessively, with only leaves growing and no flowers blooming.
; Secondly, improper fertilization, excessive application of nitrogen fertilizer and insufficient phosphorus and potassium fertilizers, leads to excessive nutritional growth of plants and inhibition of reproductive growth; The third reason is that there is no pruning, the branches are too dense, and the nutrient consumption is too high, which cannot supply flower bud differentiation.Solution: Increase lighting to ensure at least 6 hours of direct sunlight per day;
; Adjust the fertilization ratio, reduce nitrogen fertilizer usage, increase phosphorus and potassium fertilizers, and apply potassium dihydrogen phosphate solution every 7-10 days during the bud stage; Timely pruning, cutting off overly dense and excessively long branches, promoting flower bud differentiation. Question 2: What should I do if the leaves of china rose Bonsai turn yellow?Reason: Firstly, improper watering, excessive watering leading to root rot, or insufficient watering leading to drought, can cause yellowing of leaves;
; Secondly, the soil acidity is not suitable. china rose Bonsai prefer slightly acidic soil, and soil that is slightly alkaline can lead to yellowing of leaves; Thirdly, there is a lack of fertilizer, nitrogen, iron and other elements, which can lead to yellowing of leaves. For example, when nitrogen is deficient, the leaves will turn yellow as a whole, and when iron is deficient, new leaves will turn yellow, while old leaves will be normal.Solution: Adjust the watering amount according to the watering principle, remove the pot in a timely manner when watering too much, trim the rotten root system, and replant;
; When the soil is alkaline, add a small amount of ferrous sulfate solution when watering to adjust the soil pH; When there is a shortage of fertilizer, corresponding fertilizers should be supplemented according to the type of deficiency. Nitrogen fertilizer should be applied when there is a nitrogen deficiency, and ferrous sulfate should be applied when there is an iron deficiency.? Question 3: What should I do if china rose Bonsai wither quickly after flowering?
Reason: Firstly, there is insufficient light, which weakens photosynthesis during flowering and cannot provide sufficient nutrients for the flowers, leading to premature withering of the flowers.
; The second reason is that the temperature is too high. During the high temperature in summer, flowers are prone to dehydration and wither prematurely; Thirdly, there is a lack of nutrients. During the flowering period, more nutrients are consumed and not replenished in a timely manner, resulting in the withering of flowers due to insufficient nutrients.Solution: Ensure sufficient light during flowering and avoid placing in dark places;
; During high temperatures in summer, shade appropriately, lower the ambient temperature, and spray water around the plants to cool down; Apply a thin layer of fertilizer before the flowers bloom to provide sufficient nutrients and prolong the flowering period.10.
