How to cultivate perfume roses

Soil management

Roses are not very demanding on soil quality and can grow in ordinary mixed soil, but it is best to use loose, fertile, slightly acidic soil. You can add some ferrous sulfate to ordinary mixed soil. When potting, you should first spread a layer of base fertilizer at the bottom of the pot. Pay attention to the air permeability of the soil. The roots of this flower are mainly distributed in the soil layer 30-40cm deep, so when plowing, you should plow to a depth of 60cm to ensure that the soil is loose and breathable.

Moisture Management

Watering of tea roses should be adjusted appropriately according to the season and growth conditions. Spring and autumn are the peak flowering periods of this flower. At this time, it is necessary to ensure sufficient water and increase the amount and frequency of watering appropriately. If you want to prune the rose, you must control the watering before pruning to stabilize the growth of the plant. After pruning, increase the amount of watering to promote the growth of the rose. If the soil's water-locking ability is weak, the frequency of watering should be adjusted reasonably. If the soil is very sticky and has good water retention, you should pay attention to reducing the amount of watering accordingly, otherwise it will cause the rose roots to rot and wither.

Fertilizer management

Tea roses prefer heavy fertilizers, and organic fertilizers such as compost are most suitable. Each rose requires about fifteen kilograms of fertilizer. The flowering period of perfume roses is relatively long. During the development process, it is important to pay attention to frequent fertilization. Generally, top dressing is mainly based on potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer, which can effectively promote its growth and facilitate flowering.

Pruning and maintenance

In order to make the tea rose sprout more new branches, pay attention to pruning the plants. The best time to prune the plant is during its dormant period. When pruning, simply shorten the branches and cut off the new buds growing inward. One year after planting, you can cut off all the thinner branches and then cut off half of the strong branches, which will help improve the quality of flowering. For scented roses that are over three years old, they need to be pruned every year to maintain the overall beauty of the shape.

Pest control

Tea roses are often attacked by black spot disease, powdery mildew, red spider mites and aphids, so you should pay attention to timely sterilization and pest control. The plum rain season and the hot and humid summer are the peak seasons for diseases and insect pests, and the frequency of spraying pesticides and sterilization should be increased to prevent diseases and insect pests.
