The reason for the yellowing of the leaves of Dragon Blood Tree

There are shade-tolerant species growing under the forest, such as Phyllostachys pubescens, Brazilian iron, etc., and there are also species that grow in full sunshine, such as small flower dragon blood tree, sword leaf dragon blood tree and dragon blood tree. Because most of the plants of the genus Dragonblood have thick stems and thick leaves, they have a certain degree of drought tolerance, even if they are not watered for a week, they will not die, relying on their own stored water to continue to carry out normal photosynthesis. But the drought should not last long, otherwise the leaves will turn yellow and fall off due to lack of water, and even if they do not die, they will be left with a bare rod and lose their ornamental value.

Summary of several reasons for the yellowing of the leaves of Dragon Blood Tree:

The main results are as follows: 1. In the process of flower maintenance, we need soil with suitable acidity and alkalinity, and we need to turn the basin and change the soil for about 2 years, in order to give more space and nutrition for root growth.

2. In the process of changing the basin, although we are very careful, the root hairs with absorption function will still be damaged to a certain extent, so it takes a period of time to slow down the seedlings and can not be maintained normally. If you continue to water and fertilize at the slow seedling stage, the damaged roots are easy to rot, resulting in yellowing and shedding of leaves. If only a few leaves turn yellow, it is generally a normal phenomenon at the time of slow seedling.

3. The yellowing of new leaves is due to lack of fertilizer, so it is appropriate to apply fertilizer thinly and diligently, but there is no need to apply fertilizer in winter. The leaf tip is dry because the water is not thoroughly watered. In addition, let it bask in the sun properly.

4. If the culture environment is not ventilated, it should be ventilated and transparent.

5. Keep the air humidity (85%) and high temperature. Spray water on the leaf surface when the air is dry.

6. too much watering, the basin soil is too wet for a long time, resulting in lack of oxygen in the soil, causing some fibrous roots to rot, hindering normal respiration and absorption of water and nutrients, causing leaves to turn yellow and fall off.

7. The growth environment should have sufficient light, but it can also withstand semi-shade or temporary shade. But in summer, for the color of leaves, it is best to avoid strong light.

8. If yellow leaves fall off in a large area, it may be caused by diseases and insect pests. If there is damage caused by shell insects, you can wipe it clean with a dishcloth, or directly spray special insecticides, such as parathion, scale will die, and so on.
