It is suitable to change pot in winter and spring. First, use a screwdriver to pry the soil on the edge of the basin to separate the basin soil from the basin wall. When the soil is loose, remove the plant from the pot. Trim rotten and old roots, and then soak them in carbendazim for disinfection. Select a new basin of appropriate size, pad with broken tiles and sandy soil, and replant the plant. After that, do not water, give proper light, and then water 2-4 days later.
