Maintenance and management of boxwood bonsai

Populus tomentosa bonsai has become an art treasure because of its small evergreen leaves and slow growth. Generally speaking, most of the poplar bonsai materials are taken from the old wild piles by the water. Populus tomentosa bonsai is relatively delicate, and it is difficult to cultivate it successfully. The editor introduces the maintenance and management methods of boxwood bonsai as follows.

Watering

Huang Yang likes to be moist, and bonsai needs to be watered frequently to keep the basin soil moist, but not stagnant water. During the high temperature in summer, water should be watered and foliar water should be sprayed in the morning and evening.

Fertilizer application

During the growing period from May to August, the rotten thin cake fertilizer and water should be applied for 2 or 3 times, and the base fertilizer should be applied once in winter, either with compost or dry cake manure.

Pruning

Cut off overgrown branches, overlapping branches and extra branches that affect the shape of the tree at any time during the growing period. Populus tomentosa sprouts faster, generally after sending new shoots, the first 1-2 nodes will be cut off to prevent overgrowth. After fruiting, boxwood should be picked in time so as not to consume nutrients and affect the growth of trees.

Turn the basin

It is usually carried out once every 2-3 years, and it is better to do it before germination in spring. Combined with turning the basin to cut off part of the old roots and over-long and dense roots, replace the old soil and plug it with fertile and loose culture soil to facilitate the root system development.

Pest control

The main pests of yellow poplar are shell insects and yellow poplar rulers, which can be killed by manual brushing or sprayed with 1500 times of 80% dichlorvos, or with 40% omethoate 1000-2000 times. The main disease is coal fouling disease, which will cause defoliation. The key to prevention and treatment is to remove shell insects, and often spray foliar water to wash dust to make it grow well.
