How to cultivate roses
Today, let's introduce how to cultivate roses and the maintenance methods for rose plants, as well as management tips in the field of green plants and flowers. Let's get to know more about it.
Known as the "Queen of Flower Species," roses are loved by many for their noble and dignified temperament, fragrant flowers, and graceful posture. In recent years, with the emergence of improved rose trees, planting rose trees in the courtyard has become a lively sight, showcasing the elegance and romance of the owner; the beautiful and unique mini rose potted plants are used to decorate living rooms, studies, bedrooms, and living spaces, highlighting their cute and elegant beauty.
Roses have a flowering period of over 180 days and are also known as "monthly reds." Roses have the effects of invigorating blood and regulating menstruation, as well as soothing the liver and relieving depression. Cultivating a pot of roses at home not only allows you to enjoy the fragrance of flowers for over 180 days a year but also beautifies the living environment and purifies the air in the house, making it a flower variety that combines practicality and ornamental value. So, how exactly do you cultivate potted roses? What issues should be considered during the maintenance process? Today, we will share five cultivation methods for roses.
1. Requirements for temperature and sunlight. The most suitable temperature for rose growth is between 15 to 28 degrees Celsius. If the temperature exceeds 30 degrees Celsius in summer, roses will bloom less, the flowers will become smaller, and the quality will deteriorate, with many pompon flowers turning into large flat shapes. In winter, if the temperature drops below 5 degrees Celsius, roses will enter a dormant state. Roses thrive in warm environments with abundant sunlight, so the daily sunlight exposure should reach at least 6 hours. The more sunlight, the more vigorous the rose growth, with more vibrant colors and stronger fragrance that can be smelled from afar. However, avoid direct sunlight in summer as it can burn the petals, causing the edges to wither and turn brown. Therefore, proper shading should be done around noon in summer.
2. Selection of soil and pots. Roses prefer rich organic matter, loose and breathable, well-draining slightly acidic soil, and are contraindicated for alkaline and heavy clayey soil, which can cause severe compaction and directly hinder the rose's absorption of water, leading to dehydration and death. When planting roses, it is best to choose clay pots with good breathability and water permeability, or wooden planters can also be used. Before use, clean and disinfect to prevent the invasion of germs and parasites. Large potted roses can use pots with diameters of 30 to 50 centimeters, while mini potted roses can use pots with diameters of 15 to 20 centimeters.
3. How to water and fertilize. Roses prefer moist soil and are relatively drought-resistant. During the growing period, water when the soil is dry and water thoroughly. It is best to water in the morning in spring, early morning and evening in summer, and morning in autumn and winter. Newly planted roses should be watered thoroughly, and after a week, watering can resume. During the growing season, fertilize every 15 days or so, combining it with watering. Generally, apply a well-rotted compound liquid fertilizer with nitrogen, phosphorus, and potassium in a 1:800 dilution to ensure the growth of the plant and maintain dark green leaves. Increase phosphorus and potassium fertilization before flowering, using a sprayer to spray foliage or pour it at the roots.
4. What to do after flowering. After the roses finish blooming, cut the stem from the flower to the third leaf to promote the growth of new branches and reblooming. Each time the roses bloom, control the number of flowers. For single-head potted roses, it is best to keep 3 to 5 flowers per pot; for multi-head potted roses, keep about 3 flowers per head. Too many flowers can cause the nutrients to be scattered, resulting in smaller flowers, dull color, and affecting the next blooming.

5. How to prevent and control pests and diseases. Common rose problems include black spot disease, powdery mildew, red spider mites, and aphids. Roses are prone to diseases, so it is necessary to spray pesticides for prevention during growth and flowering periods. Before spring flowering, spray roses with methyl thiophanate or carbendazim to prevent powdery mildew; after summer rains, spray to prevent black spot disease; and after winter落叶, spray lime sulfur to kill pests, which will greatly reduce the occurrence of pests and diseases the following year.
6. How to select roses. When roses are in full bloom, many rose enthusiasts go to the花鸟 market or greenhouses to choose a rose they like, but they don't know how to choose. Let me tell you the specific requirements and selection criteria for choosing roses: first, choose sturdy stems, preferably 2 to 3 branches; second, the leaves should not be wilted, and the flowers should be bright in color; third, the petals should be thick, and the flower heart should not be exposed; fourth, the outer petals should be curled, fragrant, and free of pests and diseases.
Rose propagation methods: The main method of rose propagation is cutting, done from May to June and October to November each year. Select healthy branches from the current year, cut them into 5 to 7 centimeters long, retaining 1 to 2 leaves at the top, soak the roots in rooting hormone for 2 minutes, then remove and dry before inserting them into moist medium. The cutting medium can be river sand or vermiculite, wood shavings, etc., and should be watered thoroughly in advance. Spray water on the cutting medium once every morning to keep it moist, and it will root in about 20 to 30 days. When the seedlings grow to 5 to 7 centimeters, they can be transplanted into the desired pot.
