1, water and fertilize. Cedar with good drought tolerance can be watered every 4 ~ 5 days when cultivated. Be careful that you can't accumulate water after pouring it thoroughly. It is also necessary to apply fertilizer reasonably from April to May when the growth is vigorous, and apply dilute fertilizer solution every 65,438+05 ~ 20 days to provide sufficient nutrients for the growth of cedar.

2. Adequate lighting. Cedar should be maintained in a bright place so that it can receive enough light to grow. Don't leave cedar indoors in a dark place for a long time, which will make cedar grow poorly due to insufficient light and reduce its ornamental value.

3. Trim branches and leaves. Trim the branches and leaves in time. If the branches and leaves are too dense and heavy, they will crush the branches. Cut off the thick branches and weak branches, make them sprout to control the growth height, and trim the cedar to make it more beautiful.

4. Precautions. Cedar will consume all the nutrients in the soil after 2 ~ 3 years of maintenance. It is necessary to take the cedar out of the basin to clean its roots, pour out half of the old soil, replace it with new loose and breathable fertile soil, and then maintain it in the shade for half a month before normal maintenance.
