Known as the "Queen of Flower Seeds" for her noble and dignified temperament, fragrant flowers, and graceful posture, roses are deeply loved by many friends. In recent years, with the emergence of improved rose trees, planting rose trees in the courtyard has become very popular, showcasing the owner's elegance and romance; the beautiful and unique mini potted roses are used to decorate living rooms, studies, bedrooms, and living rooms, highlighting their exquisite and elegant beauty.
Roses have a flowering period of over 180 days, also known as "monthly red." Roses have the effect of promoting blood circulation and regulating menstruation, as well as soothing the liver and relieving depression. Keeping a pot of roses at home not only allows one to enjoy the fragrance of flowers for over 180 days a year but also beautifies the living environment and purifies the indoor air, making it a variety of flowers that combines practicality and ornamental value. So, how exactly do you care for potted roses? What issues should be paid attention to during the maintenance process? Today, we will share five rose cultivation methods.
1. Requirements for temperature and light. The most suitable temperature for rose growth is between 15 to 28 degrees Celsius. If the temperature in summer continues to exceed 30 degrees, roses will bloom less, flowers will become smaller, and the quality will deteriorate, with many full bloom flowers turning into large flat shapes. If the temperature in winter drops below 5 degrees, roses will enter a dormant state. Roses enjoy a warm and sunny growing environment, so the daily sunlight exposure should be at least 6 hours. The more sunlight, the more vigorous the rose growth, and the more vibrant the flower color and fragrance. However, avoid direct sunlight in summer as it can burn the petals, causing the edges of the flowers to wither and turn brown. Therefore, appropriate shading should be done around noon in summer.
2. Soil and pot selection. Roses prefer rich organic matter, loose and breathable, and well-draining slightly acidic soil. They are sensitive to alkaline and heavy clay soil, which can cause severe compaction, directly hindering the absorption of water by roses, leading to dehydration and death. When planting roses, it is best to use 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. For large potted roses, use pots with a diameter of 30 to 50 centimeters; for mini potted roses, use pots with a diameter of 15 to 20 centimeters.
3. How to water and fertilize. Roses prefer moist soil and are somewhat drought-tolerant. During the growing season, water when the soil is dry and water thoroughly. It's 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. Use a well-rotted nitrogen-phosphorus-potassium compound fertilizer, diluted at a ratio of 1:800. Increase phosphorus-potassium fertilizer before flowering, either by spraying foliage with a spray bottle or applying it to the roots.
4. How to prune after flowering. After the rose flowers, cut the section from the flower to the third leaf with scissors to promote the growth of new branches and reblooming. Each time the rose flowers, control the number of flowers. For single-head potted roses, it's best to keep 3 to 5 flowers per pot; for multi-head potted roses, keep about 3 flowers per head. Too many flowers can lead to scattered nutrition, resulting in smaller flowers, dull color, and affecting the next flowering.
5. How to prevent and control pest infestations. Common rose diseases include black spot, powdery mildew, red spider, and aphids. Roses are prone to diseases, so it's important to spray preventive measures during growth and flowering. Spray methyl thiophanate or carbendazim before spring flowering to prevent powdery mildew; after rain in summer, spray to prevent black spot; after defoliation in winter, spray lime sulfur to kill pests, which will significantly reduce the occurrence of diseases and pests the following year.
6. How to choose roses. When roses are in full bloom, many rose enthusiasts go to the花鸟 market or nurseries to select 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 stems that are thick and sturdy, with 2 to 3 branches being ideal; second, the leaves should not be wilted and the flowers should be bright in color; third, the petals should be thick and the flower center should not be exposed; fourth, the outer petals should be curled and fragrant, without any signs of disease or pests.
Rose propagation methods: The main method of rose propagation is cutting, typically done from May to June and October to November. Select healthy branches from the current year, cut them into 5 to 7 centimeters, retain the top 1 to 2 leaves, soak the roots in rooting hormone for 2 minutes, then remove and dry before inserting into moist media. The cutting media can be river sand, vermiculite, or wood shavings, which should be thoroughly watered in advance. Spray the cutting media with water once in the morning every day to keep it moist, and after about 20 to 30 days, the cuttings will root. When the seedlings grow to 5 to 7 centimeters, they can be transplanted into the desired pot.
