Reasons and Rescue Methods for Blackening and Withering of the Leaves of the Dendrobium huoshanense
A comprehensive explanation of the reasons for the blackening and withering of the leaves of Dendrobium huoshanense and the rescue methods related to green plants. Here is a detailed introduction.
Reasons and Rescue Methods for Blackening and Withering of the Leaves of Dendrobium huoshanense
The blackening and withering of the leaves of Dendrobium huoshanense are caused by reasons. Usually, the intense sun exposure in summer can lead to the blackening and withering of its leaves. At this time, it is necessary to keep it in a bright and diffused light area, remove the sunburned leaves, and then spray water appropriately to promote recovery. Excessive watering is another important reason. Dendrobium huoshanense should maintain proper moisture during growth, but it cannot tolerate waterlogging. Once the watering is too frequent, it will cause water accumulation at the roots, leading to root rot and blackened leaves. Therefore, reasonable watering is required.
Dendrobium huoshanense is a unique and precious species in China, classified as a second-class rare and endangered plant by the state. From its distribution range, it only exists in the Jingshan area of Hubei Province. It has a robust trunk, strong and twisted roots, and is relatively easy to cultivate compared to other bonsai materials. It grows fast, is tolerant to pruning, and recovers quickly.
Generally speaking, it doesn't require too much attention and won't have any major issues. However, if you want to keep it well, there are many issues to pay attention to. Otherwise, the bonsai will just survive, and its appreciation value will be greatly reduced. For instance, neglecting management may lead to leaf drop.
Why does Dendrobium huoshanense experience yellowing, withering, and leaf drop? There are two situations for leaf drop: natural leaf drop and damage-induced leaf drop.
Situations of Leaf Drop in Dendrobium huoshanense
Natural Leaf Drop
Seasonal normal leaf drop usually manifests as a few old leaves near the main branches turning yellow and falling, which will not affect the tree shape.
When repotting, if the plant has lush branches and leaves while the roots are pruned more, there will also be a slight leaf drop. This is a normal process of plant growth and metabolism, and there is no need to worry too much.
Damage-Induced Leaf Drop
If it is a damage-induced leaf drop, more attention is needed. This type of leaf drop is relatively easy to identify, usually accompanied by some issues, such as blackened, white, and wrinkled leaves.
Blackening and Withering of the Leaves of Dendrobium huoshanense
1. Insufficient Light
If the Dendrobium huoshanense bonsai is kept in an environment without light and ventilation for a long time, combined with overly moist potting soil, it is prone to leaf drop.
This often manifests as blackened leaves and most leaves dropping near the main branches of the small branches, while the new leaves at the tips of the branches are intact. This is because the roots are suffocating or damaged due to lack of oxygen.
2. Water Loss or Waterlogging
Whether Dendrobium huoshanense frequently loses water or is too moist, it can lead to abnormal leaf drop. Although Dendrobium huoshanense is a plant that enjoys sunlight and is heat-tolerant, there is still a big difference between growing as a bonsai and in the ground.
With less soil in the pot and poor water retention, when exposed to strong sunlight in summer, it will consume too much water, causing some burning and resulting in leaf drop.
The above is an introduction to the reasons and rescue methods for the blackening and withering of the leaves of Dendrobium huoshanense, which can be used as a reference suggestion.
