Causes and Control Methods of Leaf Yellowing in Winter Red Fruit Bonsai
Winter red fruit flowers easily and has a high fruit-setting rate. Its fruits are entirely red, and the fruiting period can extend to the next year's flowering and leafing stage without dropping. It is an excellent variety for fruit-viewing bonsai and is deeply loved by the people. However, during cultivation, due to the limitation of pot capacity and other influences, the leaves often turn yellow and drop. The main causes of yellowing are as follows: Temperature.

How do potted miniature chrysanthemums overwinter? Master these overwintering methods
1. Soil burial, or burying the lower part in soil while covering the upper part with dry leaves. Before the frost season arrives, potted miniature chrysanthemums can be kept in their pots or removed from them, and for the burial covering use plain wet soil. First, it is forbidden to use fertilized soil or soil mixed with firewood, grass or leaves, because plain soil will not mold or generate heat that harms the chrysanthemum roots and plants. If the lower part is buried in plain wet soil and the upper part is then covered with dry leaves, even if the leaves become wet from snow they will dry out in the wind after sunny weather, and will not cause great harm to the chrysanthemum plants. Second, it is forbidden to keep watering after burying, because they are already buried in wet soil, and the miniature chrysanthemums lie dormant under the soil, neither growing nor consuming water,

Overwintering edible fungi: raise the temperature and maintain humidity
December is the busiest period for edible fungus production. Most cultivated varieties are fruiting, some that fruit in spring are in the mycelial growth phase, and some spawn is being made or is in the mycelial growth phase. With the arrival of December, temperatures drop, which is a considerable challenge for edible fungus growth. Therefore, mushroom growers must plan reasonably, manage well, and ensure normal growth of the edible fungi. Oyster mushrooms are mostly at the fruiting stage, and some cultivated in autumn have entered the tail end of fruiting. The focus of management is heat preservation, resolving the contradiction between raising the temperature and maintaining humidity in the mushroom shed and ventilation.

How to grow shiitake mushrooms in winter for high yields
Selecting blocks: Take the shiitake blocks and logs that have been fully colonized by mycelium and dry them thoroughly, then choose uncontaminated, intact blocks or logs for treatment. If the old mycelial skin is too thick, you can scratch the surface to stimulate it, and use them only after the mycelium has healed. Soaking in hot water is an ideal method for forcing mushroom buds when cultivating shiitake in winter. When soaking the blocks, heat the water to 33°C, then put the shiitake blocks or logs into the pool and soak for 3—5 hours. If the water temperature drops, add boiling water to adjust the water temperature to 18°C—33°C, then remove the soaked
