What to do if the leaves of the cassia tree turn black and wilt like they are burnt

The reason for the blackening and wilting of the leaf tips of the cassia tree may be due to improper potting and soil replacement. The cassia trees bought back from the local area are usually planted in local garden soil, which is not suitable for indoor cultivation because of poor ventilation and improper watering. The most obvious sign is that the soil in the middle becomes compacted, leading to blackened and wilted leaf tips.

What happens when the leaves of the cassia tree turn black and wilt

Recently, some plant enthusiasts have asked why their cassia trees always have dry and yellow leaf tips. This is not an isolated issue, especially for those who grow cassia trees indoors.

Let's analyze the root cause of this problem. In fact, there are several situations that can cause the leaf tips and edges of cassia trees to dry out. The most common situation is not observing the roots during potting or soil replacement. Most of these issues are related to the roots. So, what should we do if the leaves of the cassia tree turn black and wilt like they are burnt?

Improper potting and soil replacement

Many people buy back cassia trees that come with local garden soil, which is very suitable for the local environment.

But most cassia trees are from the southern region, such as Fujian (C-S), where the air is suitable for cultivation and the soil is a sticky red soil. This type of soil is more suitable for outdoor or greenhouse cultivation. If you bring it indoors for cultivation, the ventilation conditions may not be good.

Improper potting can easily lead to problems. Many people, after getting the cassia tree, directly plant it with the original hard soil ball, while the edge of the pot uses very loose nutrient-rich soil.

This loose soil, combined with the hard soil in the middle, can make it difficult to water the hard soil in the middle. If the water doesn't penetrate, it can easily form a layered soil, making it look like it has been watered through, but in fact, the middle is still dry. The roots can't absorb water, leading to dry and shriveled leaves and the phenomenon of leaf tip dryness.

So, when you get such a cassia tree, you should wash the roots and replace them with nutrient-rich soil when potting. Soak the original soil ball in water from a large pot, clean it thoroughly, and then replace it with nutrient-rich soil. This will prevent the formation of layered soil, and the roots will absorb water, making later care easier.

If you are cultivating outdoors or in a well-ventilated area, you may not need to replace the garden soil in the middle. However, when adding soil around it, you should mix soil with garden soil and river sand in a 1:1 ratio. This type of soil has a similar softness to the original garden soil and is less likely to form layered soil when watering.

Normal metabolism

If your cassia tree is growing normally, but the old leaves at the bottom show signs of leaf tip dryness and yellowing.

This is not a problem and does not require attention. It is a normal degeneration. It mainly manifests as dryness along the edges of the old leaves, gradually spreading to the veins, and then causing the entire leaf to fall off. However, the new leaves are growing well, so there is no issue.

Root damage

If you have just repotted or over-fertilized, causing root damage, or if over-fertilization has caused root burning, and the soil is dry for a long time, it can lead to leaf tip dryness, leaf curling, leaf spot disease, and leaf blight. Therefore, when these leaf blight symptoms appear, we should look for the cause in the roots, not just spray and moisturize the leaves.

Actually, the cause is always in the roots. Of course, it is also possible that frequent overcast days followed by sudden sunshine on the new leaves can cause leaf tip dryness. This is a sudden reaction to changes in sunlight, and it is rare.

Conclusion: The issues with the leaf tips and burned tips of the cassia tree are mainly these. Once the root problems are solved, the leaves will be greasy and the flowers will fill the room with fragrance.
