What should I do if the leaves of the newly bought desert rose turn yellow?

Environmental changes

Desert rose is often classified as a succulent plant. It has a large stem and can survive in arid environments. It is not tolerant to humid environments. Therefore, if it is watered too much or exposed to too much rain during the rainy season, coupled with poor air circulation and weak light, the leaves of the desert rose will turn yellow. If the situation is serious, the entire plant will rot and die.

Solution

We need to understand its growth habits in daily maintenance, and carry out reasonable maintenance according to the condition of the disease to prevent it from happening.

Overwatering

Excessive watering is also an important reason for yellowing leaves. Desert Rose is not tolerant to moisture, so the amount of watering should not be too much, otherwise it will cause water accumulation at the roots, leading to root rot, causing the leaves to turn yellow and fall off, or even wither.

Solution

Cut off the rotten roots and pay attention to the proper watering of the Desert Rose. Do not water too much or water too little. The Desert Rose is drought-resistant, so it does not need too much water.

Low temperature fertilization

The climate is cold and the temperature is low in winter. The Desert Rose enters a dormant period at this time. Its leaves will dry up and fall off to reduce the evaporation of its own water and protect itself. Do not apply too much fertilizer or too concentrated fertilizer at this time, otherwise it will cause the leaves to turn yellow or even die.

Solution

Maintain a suitable temperature and apply a reasonable amount of fertilizer, not too much. It is best to cultivate the desert rose in a greenhouse.

Poor ventilation

Desert rose likes a warm and ventilated growing environment. Poor ventilation will cause the roots of the plant to rot and the leaves to turn yellow.

Solution

Place the desert rose potted plant in a ventilated location indoors, such as a balcony, windowsill, etc.

Pests and diseases

Pests and diseases are also important reasons for the yellowing of desert rose leaves. Its main pests and diseases are scale insects. When the disease occurs seriously, it will cause the entire plant to fall off, growth stagnation, and even death.

Solution

If scale insects are found, they should be sprayed with 2000 times diluted 40% oxydemeton-methyl emulsifiable concentrate for prevention and control.
