Common problems with balcony rose care and key points for growing them well

Growing roses on a balcony: because conditions are limited, there are too many problems when growing them. Even veterans at growing roses find it hard to handle the awkwardness of growing flowers on a balcony.

Overall, growing roses indoors faces problems in three aspects. First, poor light. Poor light does not mean turning the roof and all four sides into a glass house; if it becomes a sunroom, that still does not mean the light is good. Good light mainly has two aspects: on one hand, direct light; on the other hand, ultraviolet rays. Direct light lets the leaves receive enough light for photosynthesis, and ultraviolet rays can stimulate the leaves to produce enough waxy layer, so that the leaves are tough. Even a single layer of glass or plastic sheeting can completely block ultraviolet rays; I tested this when I was a medical student. Second, poor ventilation. Unless the surrounding walls are removed, simply opening the windows does not count as good ventilation. Third, dryness. Because it is impossible for the floor indoors to stay wet all the time, the air is relatively dry, and this same awkwardness also exists in greenhouse production of roses. It is precisely for this reason that when roses are grown indoors, the leaves are thin, the waxy layer is insufficient, and red spider mites, powdery mildew and so on breed.

However, if these factors are deliberately controlled by human effort, increasing ventilation, humidity and light, there are still certain methods to follow for growing roses well. First, choose varieties, and try to choose disease-resistant ones with a small plant shape, for example, you can choose grafted lollipop roses, so the plant height is raised and relatively speaking ventilation is a bit better. Otherwise, with cutting seedlings, the branches all lie on the potting soil, and it is very easy to breed pests and diseases. For example, the hide-and-seek lollipop tree rose is very good, with a small plant shape and frequent flowering. For roses grown indoors, first, the potting soil must be loose and breathable and must not hold water, that is, after watering, the water can completely flow out from the bottom of the pot within 1-2 minutes. Second, pay attention to using medicine. On one hand, you can regularly sprinkle some medicine on the potting soil, which can prevent pests from breeding in the potting soil. On the other hand, frequently spray fungicide on the leaves to prevent fungal diseases. Finally, prune in time. After flowering, promptly cut off the spent flowers. Try to cut off inward-growing branches, weak branches at the base, and crossing branches as much as possible, keeping the seedling well ventilated.
