How to raise lilacs and bloom more?
1, fertilization
In order to have more flowers and a large amount of flowers, fertilization should be done well. Under normal circumstances, some phosphorus, potassium fertilizer and nitrogen fertilizer should be applied. The amount of fertilizer used per plant should not exceed 50 grams, and then 20 grams of nitrogen fertilizer can be added. Applying/kloc-0 decomposed compost every year or every other year before winter can supplement the nutrients in the soil.

Step 2 water it
It is very important to water lilacs if they want to blossom vigorously. Every spring, lilacs need to be watered 1 time before and after bud germination and flowering. Lilacs grow vigorously and bloom continuously from April to June. At this stage, water should be done well, 2-3 times a month. After entering the rainy season in July, outdoor potted plants should pay attention to drainage and flood prevention.
Step 3: Trim
Pruning of lilacs is generally carried out in spring, mainly to cut off weak branches, too dense branches and diseased leaves. When lilacs bloom, cut off the residual flowers and spikes, and at the same time remove the dense branches to ensure the ventilation and light transmittance of the plants. After lilacs fall leaves, all the diseased branches and dead branches on the branches should be cut off, and the branches with dense branches should be truncated to ensure the uniform distribution of branches and leaves and beautiful tree shape.
4. Change pots
Lilacs need to change pots every 2-3 years, remove plants from pots, prune roots, remove some old roots and long roots, and replace them with new culture soil, so as to facilitate root development and flourish.
