When does the Yingshanhong stump shed its leaves?

The soil for changing pots with stumps is mainly humus soil, paddy soil and mountain mud. When changing soil, some nutrients can be properly added to the soil to ferment and volatilize into slow-release nutrients in the soil, so that the stump can benefit slowly. As for the grasp of soil pH, it depends on the specific situation of tree species. When changing pots, a screen or tile is usually fixed at the hole at the bottom of the pot. First, soil with larger particles is added to facilitate drainage, and then a stump is placed, which is filled with finer particles in the culture, and inserted tightly with bamboo sticks and sticks. The watering amount depends on the tree species.

The turnover of tree bonsai can be determined according to the following aspects:

① Generally, small bonsai should be turned over every 1 ~ 2 years, medium bonsai every 2 ~ 3 years and large bonsai every 3 ~ 5 years. If it is an old stump site, you can turn the pot every few years.

(2) For the tree species with vigorous growth and fertilizer preference, the times of turning pots should be more and the interval years should be shorter; Tree species that grow slowly and require less fertilizer can turn pots less and have longer intervals. Old piles of pines and cypresses should not be rummaged.

(3) Trees with lush foliage and well-developed roots should turn over pots frequently. Turnover can be determined by the growth of roots. When the soil in the pot is not dry or wet, turn the pot upside down and pat the bottom of the pot with your hand, so that all the trees with roots and soil can be dug up. Check the hardening of the clods and the distribution of roots. If the clod is hardened and the bottom of the clod is densely covered with roots, it means that the pot must be turned over.

It is best to choose the dormant period of trees when turning pots, mostly in early spring or late autumn. If there is a lot of original soil, you can turn over the basin at any time, regardless of the season. If it is necessary to replace most or all of the residential soil, the appropriate pot turning period should be strictly selected.

Placement and protection

The placement of stump bonsai should also be determined according to the characteristics of tree species. Generally, it should be placed in a ventilated and light-transmitting place, with a certain spatial humidity, insufficient sunshine and poor ventilation, which can make plants yellow and lead to diseases and insect pests until death. But some trees like shading, and some stumps need more sunshine, so measures such as shading or shading should be taken. For example, some evergreen broad-leaved or non-broad-leaved tree species, such as boxwood, rhododendron, camellia and so on. , more like yin, and crape myrtle, ginkgo, begonia and so on. I like sunshine, so I have to decide according to the specific situation. Some stump bonsai also have cold tolerance or non-cold tolerance. Non-cold-tolerant stumps generally need to enter the greenhouse for maintenance and management in winter, such as banyan trees and Fujian tea.
