What is the reason for the exhaustion of azalea tips?

The tip failure of Ardisia rhododendron may be caused by long-term exposure to sunlight or keeping plants away from sunlight. If it is watered too much, it will be seriously short of water during maintenance, and its leaves will also have problems. Leaf failure may also be caused by improper nutrition control. If infected with germs, its leaves will also dry up.

Rhododendron 1 Causes of leaf failure, lighting problems.

What is the reason for the exhaustion of rhododendron leaves? It should be analyzed according to the specific situation of aquaculture. Rhododendron is exposed to the sun for a long time in the process of reproduction, which will make its leaves dry due to lack of water. Keeping away from a little sunlight will cause problems due to insufficient photosynthesis, so it should be maintained under weak astigmatism.

2. Water shortage problem

If too much water is used during the growth of rhododendron, the roots will rot, which will lead to the failure to absorb nutrients normally and the leaves will gradually dry up. If the soil is dry for a long time, its leaves will dry up because of lack of water. Generally speaking, this problem can be avoided by keeping the soil moist during maintenance.

3. Nutrition problems

Excessive fertilization and lack of nutrition in the planting process of rhododendron will also make its leaves dry. One is that overnourished plants can't grow normally, and the other is that undernourished plants will dry up if they can't keep up. Therefore, balanced fertilization should be applied on time when planting azaleas.

4. Pests and diseases

If the above factors can be ruled out, then we can consider whether the tip of the blade is exhausted due to pests and diseases. The leaf tip failure caused by pests and diseases will be more obvious, and its failure degree will be more serious and its area will be larger. If it is caused by pests and diseases, it should be treated with professional drugs.
