Latest Analysis of the Causes of Yellowing Leaves on Desert Rose
Desert rose is a succulent plant in the Apocynaceae family. Previously, Qinnong Network introduced the cultivation methods for desert rose. Today, Qinnong Network brings you a problem encountered when growing desert rose, which is what to do when the leaves of desert rose turn yellow during cultivation. Qinnong Network lists five causes that can lead to yellowing leaves on desert rose, and provides corresponding solutions. Let us take a closer look below.
1. Harsh Environment
Desert rose originates from near deserts. Although it does not grow directly in deserts, it does have some characteristics of desert plants, such as being able to survive in arid environments and being intolerant of humid environments. Therefore, if the environment where desert rose is grown has poor air circulation, weak light, and is further affected by watering or rain, it will cause the leaves of desert rose to turn yellow. In severe cases, it can also cause the entire desert rose plant to rot and die.
Solution:
The most important thing is still to be familiar with the growth characteristics of desert rose, and to provide it with the best possible growing conditions during cultivation. For details, please refer to the desert rose cultivation methods on our Qinnong Network. If yellow leaves appear, reasonable care should be given according to the condition to prevent it from worsening.
2. Overwatering
Overwatering is also an important cause of yellowing leaves. Desert rose is intolerant of humidity, so the amount of water given should not be too much. Otherwise, it will cause water accumulation at the roots, leading to root rot, which in turn makes the leaves turn yellow and fall off, or even wither.
Solution:
Cut away the rotted roots, and pay attention to reasonable watering of desert rose. Do not give too much water; water sparingly. Desert rose is drought-tolerant, so it does not need too much moisture.
3. Temperature Too Low
In winter, the climate is cold and the temperature is low. Desert rose enters its dormant period at this time, and it may dry out and drop leaves in order to reduce its own water evaporation and protect itself. At this time, do not fertilize too much or too heavily, otherwise the leaves will turn yellow or the plant may even die.
Solution:
Winter care requires ensuring a certain temperature. If necessary, it can be moved indoors or placed in a greenhouse for cultivation. If greenhouse conditions are not available, you can cover it with plastic film to create a simple greenhouse effect.
4. Poor Ventilation
Desert rose likes warmth and a well-ventilated growing environment. Poor ventilation will cause root rot and yellowing leaves.
Solution:
If growing it indoors, you can place the potted desert rose in a ventilated spot indoors, such as a balcony or windowsill, or usually put it outdoors for ventilation. Do not leave it indoors for long periods.
5. Effects of Pests and Diseases
Pests and diseases are also an important cause of yellowing leaves on desert rose. The main pest affecting desert rose is scale insects. When the infestation is severe, it can cause the whole plant to drop leaves, stop growing, and eventually die.
Solution:
Scale insects can usually be observed with the naked eye. At this time, you can use a soft brush to gently brush the leaves and sweep away the pests. If the infestation is relatively severe, pesticides must be used to kill them. A 40% omethoate emulsifiable concentrate 2000x solution can be used for spraying and control.
The above are the causes of yellowing leaves on desert rose and the corresponding solutions introduced by Qinnong Network. In fact, to grow desert rose well, the key is still to pay attention to its growth habits and to observe more for the appearance of pests and diseases during routine care. In this way, it can be grown very well.
