The rotten roots of rich trees are usually caused by stagnant water in the basin soil. There is too much water in the basin, the root is in a wet environment for a long time, breathing is blocked, and the root will become soft and rotten.

There are two main causes of stagnant water in the basin. First, too much watering; second, poor ventilation, too humid and muggy.

2. Diseases and insect pests

When the rich tree is infested by diseases and insect pests, it will also lead to rotting roots. Due to the poor water quality and wet basin soil, it is easy to breed diseases and insects, nibble on the roots and cause rot.

Common diseases and insect pests on rich trees are powdery mildew, root rot and root rot nematodes parasitic in the soil.

When the leaves of the plant turn yellow and the bark becomes soft, trim the roots in time. Cut off the yellowed leaves, leaving only the bud eyes. Remove the woody stem, do not deal with the root system, and clean the soil at the bottom. The roots will be trimmed with scissors, and the rotten parts will be cut off. If the rot is serious, the messy roots will be cut off directly. If the stem also begins to rot, you need to remove the rotten part and turn it into a piece. Put the treated rhizome in methyl topiramate or potassium permanganate solution and soak for 24 hours, or spray the wound with Sukeling. Then dry in a cool and ventilated place and replant it.

When raising rich trees at ordinary times, we should pay attention to prevent the occurrence of stagnant water. After discovering the rotten roots of the rich tree, the following steps can be taken:

1. Ventilate in time to keep the environment dry.

3. Remove the rotten part of the root of the rich tree, spray the wound with Sukeling, dry it and plant it.

4. when it is found that the rotten roots of the rich tree are in the initial stage, disinfect the soil in time, and use some sterilized drugs as auxiliary treatment, such as bacillus special wettable powder and so on.

[how to prevent the occurrence of root rot]

1. Soil matrix

If you want to cultivate a healthy rich tree, you need to provide it with excellent soil matrix and good air permeability.

The cultivation substrate with good permeability and water permeability can be prepared, and the medical pond mud, river sand and cooked sawdust can be mixed at 5:3:2, or mixed with mountain mud and river sand at 7:3.

You can also go to the flower market to buy special horticultural nutrition soil, as well as anti-rot and anti-rot root particles.

2. Look at the soil watering

It is an important link in the maintenance and management when watering, and the amount of water must be strictly controlled when maintaining the wealth tree.

It is found that when the soil turns white, it will be watered thoroughly. The rich tree does not need to be watered every day. It can be watered every five or six days at room temperature. It would rather be dry than wet. And usually should pay attention to the hygiene of the flowerpot, if the basin hole is blocked, should be dredged in time.

1. The choice of environment

The rich tree is adaptable, light-loving and shade-tolerant, and can grow well in light or shade. However, the rich tree will grow weaker in the dark for a long time, and the strong light in summer will lead to the leaf tip and scorched edge of the rich tree. Therefore, when raising rich trees, we should pay attention to put them in a well-ventilated and bright place, and avoid direct glare.

2. Selection of basin soil.

Pot cultivation of rich trees generally choose loose vegetable garden soil or rotten leaf soil, plus a small amount of compound fertilizer, just bought potted plants generally do not have to change the soil at the beginning.

3. Watering the rich tree

As mentioned earlier, too much watering of rich trees can easily lead to rotting roots. Therefore, the rich tree should be watered appropriately in the process of breeding, preferring less watering rather than more watering. Of course, decorations can be properly watered in summer, but be careful not to produce stagnant water.

4. Fertilizing the rich tree

Rich trees do not have high requirements for fertilizer, and generally do not need fertilization. If you want to apply fertilizer, you must apply thin fertilizer, do not apply thick fertilizer. Fertilizer can choose some common foliage fertilizer.

5. prevention and control of diseases and insect pests

Stem rot, anthracnose, cabbage worm, inchworm, red spider and other diseases and insect pests may occur in the growth process of rich trees, and pesticides can be applied according to specific diseases.
