Cultivation method of cedar

1, water management

Cedar has certain drought resistance and is afraid of waterlogging. As long as the soil in the basin is kept moist. When it is dry, water it thoroughly, but avoid water accumulation. Pay attention to timely drainage after rain to prevent cedar from rotting roots.

Step 2 apply fertilizer

Fermented and decomposed human manure and cake fertilizer are suitable for fertilization, and cake fertilizer is the main fertilizer for potted plants. It is best to control the fertilization time in April-May to avoid too much fertilizer and water, and apply it in 2-3 times.

Step 3 turn the washbasin over

Generally, it takes 2-3 years to turn the pot, which is suitable for spring germination. 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 pot, it needs to be moved to the shade 15 days, and then it can be managed normally.

prune

In the process of cedar management, attention should be paid to shaping and changing heads. Cedar is a heavy branch, and its head will be damaged or weak. You must use strong edge skills to pull and tie, which will become a central advantage in the future. This process is a head change.

Pruning is mainly to remove too dense branches, long branches, dead branches, pests and diseases. And freely shape the tree according to personal preferences. In order to prevent cedar from growing too high, it is necessary to remove the terminal bud and eliminate the top advantage, so that cedar can grow more side branches.
