1, stop watering

Stop watering at the first time, keep ventilation, and avoid excessive accumulation of water leading to the reproduction of rotten bacteria. Most of the rotten roots and skins of the rich trees are caused by excessive humidity and poor ventilation, so when the rich trees are found to have symptoms, they should stop water and take off the pots quickly.

Step 2: Take off the pot.

If the rotten area is too large for the plants to be cured, it is necessary to take off the flowerpots in time, cut off the rotten parts, rinse the roots of the rich trees with clear water, and then cut off the rotten roots, skins and dead leaves, which can effectively prevent reinfection and give the plants a chance to regenerate.

3, disinfection and sterilization

After pruning, soaking in potassium permanganate solution or carbendazim for disinfection can effectively kill most of the germs on the plants, and finally put them in a ventilated and cool place to dry, so you don't have to worry about serving.

Wait until the water on the surface of the plant is dry, so as not to cause the rot fungus to repeat. Some plant healing agents can also be applied to the incision of the rotten wound of Nostoc flagelliforme, which can effectively promote wound healing.

Matters needing attention in the cultivation of rich trees

1, sunshine

Rich trees like high temperature, high humidity and sunshine, and cannot be shaded for a long time. Therefore, when maintaining and managing, it should be placed in a sunny place indoors. When placed, the leaves must face the sun. Otherwise, because of the phototaxis of leaves, potted plants spray water on leaves once, which is beneficial to photosynthesis and will distort the whole branches and leaves. In addition, spraying once every 3 to 5 days can make the branches and leaves more beautiful.

water

Watering is an important link in the process of conservation management. Less water, stagnant branches and leaves; Too much water may lead to the death of rotten roots; If the amount of water is moderate, the branches and leaves will become bigger. The first principle of watering is wet rather than dry, followed by "two more and two less", that is, water more in summer and hot season and less in winter.

Step 3 apply fertilizer

Rich trees are flowers and trees that like fertilizer, and the demand for fertilizer is greater than that of other ordinary flowers and trees. When changing pots every year, the proportion of fertile soil can account for 1/3 or even more. Rich soil has a wide range of sources, and it can be collected from deciduous humus soil of broad-leaved trees, mixed with a little pastoral soil, miscellaneous bone powder and bean cake residue. This fertile soil is efficient and easy to obtain, but it should be fully decomposed to avoid "burning" the leaves yellow.
