Cedar cultivation methods and precautions

How to grow cedar

Moisture Management

Cedar has a certain degree of drought resistance but is afraid of waterlogging. Just keep the soil in the pot moist. Water it when it becomes dry. Water it thoroughly but avoid waterlogging. Be sure to drain water in time after rain to prevent the cedar roots from rotting.

Fertilization

It is appropriate to use fermented human manure and cake fertilizer for fertilization, and cake fertilizer is the main fertilizer for potted cultivation. The best time for fertilizing is from April to May. Avoid using too concentrated fertilizer. It can be applied in 2-3 times.

Repotting

Generally, repotting is required every 2-3 years, preferably before budding in spring. When repotting, replace half of the soil with loose and fertile new soil and cut off rotten roots. After repotting, you need to move it to a shaded place and leave it for about 15 days before managing it normally.

prune

In the management of cedar, attention should be paid to shaping and head replacement. The cedar branches are heavy, and the heads will be damaged or at a disadvantage. They must be pulled up and tied with strong side techniques, and then become the center advantage. This process is called head replacement.

Pruning mainly involves removing overcrowded branches, overgrown branches, dead branches, diseased and insect-infested branches, etc. The tree shape can be freely shaped according to personal preference. To prevent the cedar from growing too tall, the terminal buds need to be removed to eliminate apical dominance, which will allow the cedar to sprout more side branches.

Pests and diseases

When planting cedar in pots, pay special attention to preventing and controlling leaf blight. You can spray 500-800 times dichlorvos solution. If there are many insect pests, you can spray 1000-1500 times diluted 80% DDT.
