Cultivation method of cedar

Water management

Cedar has certain drought resistance and is afraid of waterlogging. Just keep the soil in the basin moist. When it is dry, water it thoroughly, but avoid ponding. Pay attention to timely drainage after rain to prevent cedar rotten roots

Fertilization

It is suitable to use fermented and rotten human manure and cake fertilizer to fertilize, and the pot culture is mainly cake fertilizer. It is best to control the fertilization time from April to May. Avoid excessive fertilizer and water. It can be applied 2-3 times

Turning Basin

Generally, the pot needs to be turned every 2-3 years, which is suitable for germination in spring. When turning the pot, change half of the loose and fertile new soil and cut off the rotten roots at the same time. After turning the basin, it needs to be moved to the shade for about 15 days before it can be managed normally

Pruning

In the process of cedar management, we need to pay attention to shaping and head changing. Cedar heavy branches, the head will be damaged or in a weak position, must be pulled up and tied with strong side skills, and then become the central advantage. This process is to change the head

Pruning mainly removes over dense branches, bare branches, dead branches and pest branches, and freely shapes the tree shape according to personal preferences. In order to prevent cedar from growing too high, it is necessary to remove the terminal bud and eliminate the apical advantage, which can make cedar sprout more lateral branches
