Rose Planting Time and Methods
Rose Growth Habits
Roses have a strong adaptability to the environment, cold and drought resistance, and are suitable for planting in slightly acidic sandy loam rich in organic matter and good drainage. They prefer a sunny environment with adequate ventilation and avoid wind. shading is needed in summer, they can tolerate cold temperatures, and enter dormancy when the temperature is below 5 degrees Celsius in winter. If the high temperature of summer lasts above 30℃, they will enter a semi-dormant state.
Rose Planting Time
Roses are generally planted in spring before they start to germinate or in autumn when the temperature drops. These two seasons have a higher survival rate for planting roses. Do not choose to plant in spring when the temperature has already started to rise.
Rose Planting Methods and Key Points
1. Soil
Roses have a wide adaptability to soil. Most varieties prefer fertile, moist but well-drained, slightly acidic soil with a pH of about 6.5. It is convenient to prepare the soil in advance and apply base fertilizer for later management.
2. Sowing
Sow when the ambient temperature is between 5℃ and 10℃. Sowing can be done by spot sowing, drilling, or potting, with a spacing of 3 cm between seeds. After sowing, cover the seeds with a layer of fine sand and water thoroughly. The seeds usually germinate after about 40 days.
3. Seedling Raising
Seeds need to be disinfected before sowing roses to improve germination rate and increase seedling emergence. Soak the seeds in clean water for about 10 hours, then mix them with medicine according to the pests and diseases that need to be controlled. After sowing, careful management is needed to promote seed germination, and seedlings can be transplanted immediately after emergence.
4. Maintenance Management
Sunlight: Roses like plenty of light stimulation and should maintain more than 6 hours of sunlight every day. This requires choosing a good location and not placing them in a long-term dark place. If the light is poor, they will only grow leaves and not bloom. Even if flowers are produced, they will not be colorful and the fragrance will not be strong.
Water: Roses like water supplementation but should not have waterlogging. The frequency of watering depends on the season. In spring and autumn, water normally. In the heat of summer, with high temperatures and more evaporation, watering is very important. Keep the soil moist and dry in winter during the dormant period.
Fertilization: Roses require fertilizer supplementation. A large amount of nutrients is needed when the flowers are in full bloom. The amount of fertilizer varies by season. In spring, fertilize every 4-5 days. In May-June, with a large number of flowers blooming, fertilize regularly to ensure adequate nutrition.
5. Disease and Pest Control
Common diseases of roses are powdery mildew and black spot, which are both manifested on the leaves. Preventive measures need to be taken in advance, such as using lime water for disinfection. Infected leaves should be cut off and then sprayed with medicine continuously, at least 2-3 times. The main pests infesting roses are aphids, and beetles also cause significant damage to the plants. Diseased branches and leaves should be removed promptly, and喷洒with medicine.
6. Harvesting
Roses can be harvested 1-2 days before flowering when the buds have not yet opened. The harvesting time also depends on the variety. Red and pink varieties can be harvested when the first two petals begin to open and the sepals are in a reversed position. Yellow varieties are harvested earlier than red and pink varieties, while white varieties are harvested later.
