1, suitable soil
In order to make violets grow vigorously, it is necessary to choose loose and fertile neutral acidic soil with good drainage as the cultivation substrate, and the pH value should be controlled between 5 and 6.5. Humus soil, garden soil and river sand can be mixed to form a cultivation substrate, which can improve the permeability and drainage of basin soil.
2. Fertilization method
There is little demand for fertilizers during the growth of violets. Potassium nitrate and calcium nitrate are the main fertilizers, and the dosage is very small. During the growth of violets, decomposed liquid fertilizer and chemical fertilizer were applied once every 65,438+00 days. After the buds germinated, 0.5% superphosphate and phosphorus-potassium fertilizer were applied again, which made the violets bloom more brightly.
Step 3 Water method
Violet is suitable for growing in humid environment, but its waterlogging tolerance is poor. Therefore, when watering violets, we must control the frequency and quantity of watering. When the climate is low in spring and summer, only a small amount of water is needed to maintain a relative humidity of 40%. In summer and hot season, water should be poured once a day to keep the soil moist.
Step 4 trim and reshape
If you want violets to flourish, you need to prune and check them frequently. When pruning, only the rotten leaves and terminal buds need to be removed, and only the side branches and leaves are kept. Note that the roots of violets are tall and thin and need to be supported immediately after pruning to prevent violets from falling.
