What is the reason for the soft stems of desert roses (what is the reason for the soft and rotten stems)

There are several reasons why the stems of Desert Rose become soft:

(1) After the roots rot, they become infected, causing the stems to rot and begin to soften.

(2) After losing water, the roots wither and become soft because the root system cannot absorb water.

(3) Excessive fertilization will cause root burn, leading to root rot and soft rot of fleshy stems.

(4) During the rainy season, bacteria breed and the soil remains moist for a long time, leading to diseases and stem rot.

(5) Minor frost damage causes minor injuries to the roots and leaves, temporary loss of function, and leads to stem rot.

If the stems of the desert rose become soft or have rotted, they must be dealt with promptly to avoid death.

If you find that the stem of the desert rose is very soft and brown water flows out when you dig it with your fingers, it is seriously rotten. You need to remove it from the pot to rescue it. The method is as follows:

(1) Use tap water to rinse off the planting material and clean the roots until all the roots are exposed.

(2) Cut off the rotten roots, and then use a utility knife to scrape off the rotten parts of the fleshy stem layer by layer until the fresh parts are exposed.

(3) Dry the wound in a cool and ventilated place. During the drying period, you can use 1000 times diluted carbendazim in water and spray it to wet the wound once every half an hour for three times.

(4) It is best to use plain soil as the planting material for replanting. Use freshwater river sand directly for planting. River sand is clean and sterile, has good drainage, and has a large temperature difference between day and night, which is conducive to rooting.

How to avoid soft rot in Desert Rose?

(1) When planting, the soil should be loose and breathable, with good drainage, light fertilizer and slightly acidic. You can use (honeycomb coal powder + humus soil + volcanic rock small particles) and mix one third each for planting.

(2) Daily maintenance: Keep the plant in a location with sufficient light and good ventilation. The temperature should be within the appropriate growth range, 15 to 32 degrees Celsius. Shade the plant when the temperature is high and protect it from freezing when the temperature is low. In spring, bacteria are active. Water the plant with a solution of carbendazim and avoid rain.

(3) Desert roses are drought tolerant. When watering, you need to allow the soil to dry out at intervals. When watering, do not water unless the soil is dry, and water thoroughly. Wait until the soil is completely dry before watering. In spring, pay attention to avoiding rain and extend the watering time appropriately.

(4) When applying fertilizer, be careful not to allow solid fertilizer to come into direct contact with the root system. You can apply it on the side of the flower pot. Fertilization should be done during sunny days, and be careful to "apply thin fertilizers frequently, and it is better to apply less rather than more."
