Why do Chili Plants Wilt?
When we get thirsty, our bodies are letting us know that we need more water. It is a feeling we have. Part of the reason for this is that we have a skeleton structure that keeps us standing straight. Green leafy plants don’t have a similar structure, they use water pressure to keep them standing upright. You can think of the plant leaf as being similar to a garden hose. With the water turned off, the hose is limp–its wilted. When we turn the water on, the water pressure inside the hose increases and the hose becomes stiff. The stiff hose no longer looks wilted. Plants work exactly the same way. In order for a plant to maintain its normal shape, it needs a certain amount of water pressure inside the leaves.
Water pressure is maintained in the leaves by the roots which are absorbing water from the soil and pumping it up into the leaves. Leaves naturally loose water, especially during photosynthesis. Water is constantly flowing from the roots to the leaves. If roots can’t get enough water, they can’t maintain the correct water pressure in the plant and the leaves drop or wilt.
If the plant is overwatered, fungal wilt is probably to blame. Spotted wilted pepper plants, leaves that are dotted with brown or black spots, yellow marking on the leaves or stem are sigs of fungal wilt.
Damaged Roots During Transplanting
When you move a plant, it will damage some of its precious roots. It is quite normal for such a plant to show wilting right after being moved.
It is quite common for people to water far too much after transplanting chilis in order to try and fix the problem. Too much water does not help the problem. One solution is to move chili plants in spring and fall when the temperatures are lower and plants are not requiring full energy. At these times of the year, water evaporation from leaves is less and you get less wilting.
If you do move a plant in summer, it will wilt much less if it is covered for a week or two so that it receives less sunlight.
How to fix wilting Chili Plants?
Take a careful look at the environment and the soil for clues.
If the weather is hot and the soil is dry, considering covering the chili plant or moving it to an alternate location. Water the soil twice daily ensuring that the soil is moistened and water doesn’t pool. If the soil is already moist watering can make things worse. Do not overwater and considering watering the plant less. Ensure the soil is well-draining.
