Time can be carried out in both spring and autumn. It is now a good season to change the soil.

Luohansong likes slightly acidic soil, when turning the basin, take the soil mass out, remove the attached old soil, and properly trim the overlong root system and rotten fibrous root. Trim over-dense branches and replace them with new cultivated soil. After changing the basin, pour through the basin soil with rooting powder and water.

Second, Luo Hansong modeling

Spring Festival happens to be a good time for the growth of bonsai trees and the shape of Luohansong. Spring pruning is carried out from the following three aspects.

1. Thinning: cut off the branches of diseases and insect pests and burn them immediately to prevent the spread of diseases and insect pests. Shape pruning, pruning according to the shape of Luohansong you designed, while trimming off overlapping parallel branches, overlapping branches, whorled branches, long branches and so on. The length of the main branch is shortened one by one from the bottom to the top, so that the whole crown forms a typical cone column.

2. Short shearing: after thinning the excess branches, it is necessary to cut short the remaining styling branches to promote the sprouting of the styling branches two or three times a year. If a bud is sent for a short cut, the branch grade of the modeled branch will be rapidly increased, and the branch order of each grade can be shortened without lengthening the branch.

3. Shrinking pruning: the perennial branches are retracted and pruned, which can make the big trees smaller, which is beneficial to the pile scene modeling.

Third, Luohansong watering
