1、 How to change the basin

1. Take out the plant: if the lilac just bought back is a bare root seedling, it doesn't need to come out of the pot. If the lilac flower has a flowerpot and the soil inside does not meet the later growth, it needs to be replaced. Do not water and fertilize before changing the pot, keep it dry, then loosen the surrounding soil, hold the pot and take out the plant

2. Pruning and disinfection: after taking out the plant, knock down the soil on the root, remove it, prepare a lot of fungicide solution, soak the root in it for disinfection, properly prune the root, cut off the rotten root and withered root, and put it in a ventilated place to dry

3. Preparation of soil: there are no great requirements for the soil. It can resist barrenness and has strong adaptability to the soil. It is OK to provide loose and soft acid soil

4. Pot planting: select the appropriate flower pot, and it is best to use the deep pot, which can make the root system stretch and grow normally. Fill the pot with soil, plant lilacs and cover the soil

2、 How

Pay attention to the maintenance after changing the basin. Do not touch the strong light first, and put it in a cool and ventilated place to slow the seedlings. After the slow seedlings are completed, they can be maintained normally, given sufficient sunlight, and reasonably apply water and fertilizer
