Lily need to change basin once a year, with fresh soil to ensure good growth, to avoid lack of growth space in basin soil. The time of basin changing is in autumn, almost after the flower withers, it will not affect the flower at this time, and it is also conducive to the later growth recovery and reduce unnecessary consumption.
Prepare the flowerpot and suitable soil before changing the basin, because it will grow every year, so the basin should be a little larger than the previous one, about 25-30cm, to ensure the growth demand. It is required to be loose and permeable micro acid soil, which can be directly purchased as ball root soil, fertile sandy soil, or rotten leaf soil, which can provide a good foundation for growth.
After preparing the appropriate pot soil, you need to take out the lily from the flowerpot, control the water content and keep it dry a few days before taking off the pot. In this way, the bulb can be taken out easily, and the harm to the bulb is less. After the lily is taken out, the soil attached to it should be removed, and care should be taken in this process.
Fill the flowerpot with a layer of soil, a layer of basic fertilizer, and then a layer of soil. Plant the lily in the middle, cover the soil and water it.
