The bonsai is serious (standing blight) every year. What causes it and how to prevent it?

The follow-up tree is an evergreen plant with luxuriant branches and leaves, graceful posture, resistance to pruning, resistance to flat binding, blooming season, full of flowers, very spectacular. When different lines mature, the leaf color and flower color are different, and the leaf size is also different, which is the preferred bonsai stump for flower friends. Huipian (standing blight) is a common disease, what is the cause? How to prevent it? Below, Huacao Le shares with you the treatment of bonsai tablets (blight).

The bonsai is serious (standing blight) every year. What causes it and how to prevent it?

First, during the period of survival on the first pile, the new roots are thin and tender. If they are not careful, the new capillary roots will break. At this time, they will be eroded by the rotten bacteria in the soil in the basin, resulting in rotten roots, the light ones will return to the piece, and the heavy ones will die. Some flower friends test that for convenience, the vegetable garden soil in the surrounding garden is used as basin soil. as a result, the film return rate and mortality rate are very high, which seems to be caused by new and rotten roots.

Solution: using plain loess plus about 25% mountain sand as basin soil, the basin time is between February and March, preferably on a cloudy day. Watering wet soil on the second day and watering thoroughly on the third day after potting, the effect is very good.

Second, some bonsai friends in the production and maintenance process of bonsai, do not regard the bonsai stocking process as a part of bonsai production, but only pruning, long-term pruning, will cause the next wood up and down nutrient and water imbalance and return to the film. Due to long-term pruning, the leaves on the plant are always aging leaves and branches, whose photosynthesis is very weak and the branching rate is low, which affects the mechanism of the plant.

Solution: in the process of wood maintenance, the stocking and breeding are combined for about 2 years, and the stocking time can be extended after the bonsai is formed. The top branch should be cut off during the stocking period, and the top branch should be rejuvenated by controlling the top branch, because the plant growth has the top advantage, if not controlled, it will only grow the top branch but not the side branch.

Third, the second tree is a fertilizer-loving plant, which needs big fertilizer during the growth period. if it is not fertilized in time, there will be a return to the film for a long time.

Solution: fertilize at least once a month except in winter. Preferably cooked cake fertilizer or chicken dung.

Fourth, relay bonsai in the maintenance process will often grow a lot of branches in the pile and root, which should be cut off in time.

Solution: because the column root of the successor tree grows new branches, it is easy to absorb the water and nutrients of the whole plant, resulting in the loss of the coordination of water and nutrients in the old plant, and even the death of the whole plant.
