How do lilacs grow and bloom?
1. Fertilization
If there are many flowers and large flowers, it is necessary to do a good job of fertilization. Generally, phosphorus, potassium fertilizer and nitrogen fertilizer should be applied. The amount of fertilizer applied per plant should not exceed 50g, plus 20g of nitrogen fertilizer. Applying decomposed compost once a year or before the following winter can supplement the nutrients in the soil.
water
If you want lilacs to bloom, watering is very important. Every spring, when lilacs germinate and bloom, they need to be watered once every time. Lilacs are in full bloom, and it is a continuous flowering season from April to June. Water should be prepared at this stage, 2-3 times a month. After the rainy season in July, outdoor potted plants should pay attention to drainage and flood prevention.
prune
Pruning lilacs is generally carried out in spring, mainly to remove weak branches, too dense branches and diseased leaves. When lilacs are in full bloom, the residual flowers and spikelets will be cut off, and the ultra-dense branches will be removed to ensure the ventilation and light transmission of the plants. After the clove leaves, all the diseased and dead branches on the branches should be cut off and cut off to ensure the uniform distribution and beauty of the branches.
Step 4 change pots
Lilac flowerpots should be replaced every 2-3 years. Potted plants should remove plants, prune roots, remove some old roots and excessive roots, and replace them with new culture soil to promote the development of roots and the reproduction of lilac flowers.
