Latest Analysis of the Causes of Yellowing Leaves in Plumeria
Plumeria is a deciduous shrub or small tree in the Apocynaceae family, with high ornamental value. As a potted plant it is widely popular in our country, and plumeria is also a traditional Chinese medicine, with effects such as clearing heat and relieving summer heat, and moistening the lungs and throat. Therefore, there are quite a lot of people growing plumeria now, but plumeria often shows yellowing leaves during growth. So what causes plumeria leaves to turn yellow? Let's take a look together with the editor below!
1. Excessive fertilization
Although plumeria has a relatively large demand for fertilizer, we need to pay attention to controlling the amount of fertilizer when fertilizing. If too much fertilizer is applied or the concentration is too high, it is easy to cause adverse phenomena such as fertilizer damage and root burning in plumeria. As nutrient absorption is hindered, the leaves lack nutrients and thus show yellowing. Therefore, if too much fertilizer has been applied, pay attention to watering in time to dilute the fertilizer. Or change the soil, and then also pay attention to controlling the fertilization position to avoid the roots coming into contact with the fertilizer and being burned.
2. Improper watering
Improper watering is also a main cause of yellowing leaves in plumeria. Too much watering will cause waterlogging in the soil, affecting root absorption and leading to root rot in plumeria leaves. This causes the plumeria leaves to turn yellow and wilt, but water cannot be lacking either. If not watered for a long time, the leaves will lack water and quickly dry up and turn yellow. Therefore, when watering, we should follow the principle of watering when the soil is dry and stopping when it is wet. Control the amount of watering according to the actual conditions of the soil and the plumeria, and do not water blindly.
3. Light reasons
Plumeria likes to grow in an environment with sufficient light. Its demand for light is also relatively large. In an environment with sufficient light, plumeria has strong growth ability. The floral fragrance is also relatively rich, but if it grows in a shaded environment for a long time, it will affect plumeria's photosynthesis. This reduces the accumulation of photosynthetic substances, and the leaves will gradually turn yellow due to lack of chlorophyll and so on. Therefore, we should pay attention to controlling light well, especially in winter and other situations where natural light is insufficient, and pay attention to doing artificial supplementary lighting work well.
4. Pest and disease control
When plumeria leaves show phenomena such as yellowing and softening. In addition to the above reasons, it may also be caused by pests and diseases. We should observe whether the leaves have other symptoms or the presence of pests. If so, find out the cause in time, then carry out prevention and control to prevent the disease from spreading. Spray insecticides and fungicides regularly every month, then pay attention to doing ventilation work well, control humidity well, and after pests and diseases occur, carry out targeted prevention and control.
The above is a brief introduction to the causes of yellowing leaves in plumeria. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
