Why doesn't the Clerodendrum grow?
This article provides a detailed explanation of the content related to Clerodendrum from the perspective of a floral clinic. Why doesn't the Clerodendrum grow? Please refer to the detailed introduction below.
Many Clerodendrum enthusiasts are puzzled why their plants do not grow. Their Clerodendrum takes a long time to produce only one or two leaves. What exactly causes this situation? There are many reasons that may lead to the stagnant growth of Clerodendrum. Below are some reasons listed based on the experience of enthusiasts in growing Clerodendrum. You can screen them according to your actual situation!
1. Unsuitable planting material: Clerodendrum is quite picky about the planting material. If the material is not suitable, it will enter a dormant state, neither dying nor growing. This is the most common situation encountered, and many enthusiasts' plants stagnate when using garden soil.
2. Root problems: Clerodendrum is a plant that easily grows roots with strong regenerative abilities, but its roots are also very delicate. I found that once the Clerodendrum's roots are damaged, the growth of new roots is hindered, or only a few new roots grow. This means that if there is a small amount of rotting roots at the bottom of the Clerodendrum, the new roots are less likely to grow. Even if they do, they cannot meet the growth requirements, causing the plant to remain stagnant.
How to avoid this? For seedlings with coconut shell and sphagnum moss, they can be dried for half a day and planted using the wet soil dry planting method. Do not water after planting and wait a few days before watering to prevent excessive watering from rotting the damaged roots. Overall, I really dislike sphagnum moss seedlings.
3. Watering issues: This problem has bothered me for a long time. In the past, I used orchid stones, bark, and decomposed leaf soil. During the planting process, I found that even after watering a lot, the bottom of the pot was still dry. When I turned the pot over, I saw that the roots of the Clerodendrum were extremely dry, with no moisture at all. It took several attempts before I realized that there were water channels in the pot, and the water quickly flowed out of the bottom, leaving the planting material very dry. Soaking the pot is also very troublesome, and this can also lead to stagnant growth.
4. Root diseases or pests: If there are nematodes or pest infestations in the roots, it can also cause stagnant growth. If root tumors (scars from pest bites) are found, the best solution is to cut them off and regrow new roots, and insecticides should be used. If scale insects infest the roots, the plant will stop growing and may even die in severe cases.
5. Weak seedlings: If the seedlings are weak, it will take time for them to become strong, naturally extending the growth cycle.
6. Forced pruning: If the seedlings are normal but still stagnant, my method is to cut, break its balance, and force it to wake up.
The above is a comprehensive explanation of the reasons for why Clerodendrum doesn't grow, hoping it can help you.
