What causes desert rose leaves to yellow?

Desert rose is a kind of succulent plant of Apocynaceae. Before, the farming method of desert rose was introduced to everyone by the pro-agricultural network. Today, the pro-agricultural network introduces a problem that will be encountered when breeding desert roses, that is, what to do if the leaves of desert roses turn yellow when breeding. Pro-agricultural network here lists five causes of desert rose leaves yellowing, and provides the corresponding treatment methods, let's take a specific look.

I. the environment is harsh

Desert rose is native to the desert, although it does not grow directly in the desert, it also has some characteristics of desert plants, such as being able to survive in dry environment, not tolerant to wet environment and so on. Therefore, if the ambient air in which desert roses are cultivated cannot be ventilated and the light is weak, coupled with the influence of watering or rain, the leaves of desert roses will turn yellow, and if serious, it will also lead to the decay and death of the whole desert rose.

Solution:

The most important thing is to be familiar with the growth characteristics of desert roses and try to give them the best growth conditions when raising them. For details, please refer to the cultivation methods of desert roses of our pro-farm network. If there are yellow leaves, reasonable care should be taken according to the condition to prevent the disease from getting worse.

Second, too much watering

Too much watering is also an important reason for yellowing leaves, desert roses are not resistant to moisture, so watering should not be too much, otherwise it will cause stagnant water in the roots, lead to rotten roots, and make the leaves yellow and fall off, or even wither.

Solution:

Cut off the rotten roots, and pay attention to the reasonable watering of desert roses, do not make too much watering, watering less, desert roses resistant to drought, so do not need too much water.

Third, the temperature is too low

The winter climate is cold, the temperature is low, the desert rose enters the dormancy period at this time, it will have the dry withered leaf situation to appear, is in order to reduce own water evaporation, carries on the self-protection, at this time fertilization should not be too much, not too thick, otherwise it will cause the leaves to turn yellow or even die.

Solution:

Winter maintenance needs to ensure a certain temperature, if necessary, it can be moved indoors or put into a greenhouse for cultivation, if there is no greenhouse conditions, it can be covered with a plastic film to make a simple greenhouse effect.

IV. Poor ventilation

Desert roses like to grow in a warm and ventilated environment, and poor ventilation will cause rotten roots and leaves to turn yellow.

Solution:

If it is indoor breeding, you can put the desert rose pot in an indoor ventilated location, such as a balcony or windowsill, or usually put it outside for ventilation, do not leave it indoors for a long time.

V. influence of diseases and insect pests

Diseases and insect pests are also an important reason for the yellowing of desert rose leaves. the main insect pests that affect desert roses are shell insects, which will lead to the shedding of the whole plant, growth stagnation and even death.

Solution:

Shell insects can usually be observed with the naked eye, at this time, you can use a brush to gently brush the leaves to sweep away the pests, if the pests are more serious, you can use 40% omethoate EC 2000 times to spray and control.

The above are the reasons for the yellowing of desert rose leaves and the corresponding treatment methods introduced by the pro-agricultural network. In fact, to raise the desert rose well, the key point is to pay attention to its growth habits, coupled with the usual maintenance of more observation of the emergence of diseases and insect pests, so that it can be raised very well.
