What causes kale to wilt, and is it still safe to eat?
Kale can wilt due to various reasons, including lack of water, too much heat, or exposure to ethylene-producing fruits. When kale wilts, it can be a sign that the leaves are no longer receiving the necessary amount of water and nutrients. This can be caused by underwatering, poor soil quality, or high temperatures. If the wilting is caused by a lack of water, it is usually still safe to eat, but the leaves may become bitter and less palatable.
However, if the wilting is caused by disease, pests, or contamination, it is best to err on the side of caution and discard the affected leaves. To determine whether the wilted kale is still safe to eat, inspect the leaves for any signs of mold, sliminess, or discoloration.

By taking the necessary precautions, you can enjoy your kale while minimizing the risk of foodborne illness.
How often should I water my kale to prevent wilting?
The frequency of watering kale depends on various factors, including climate, soil type, and the stage of growth. As a general rule, kale needs about 1-2 inches of water per week, either from rainfall or irrigation. In hot and dry weather, kale may require more frequent watering, while in cool and humid weather, it may require less. It is essential to check the soil moisture regularly by inserting your finger into the soil up to the knuckle. If the soil feels dry, it is time to water your kale.
Overwatering can be just as harmful as underwatering, so it is crucial to find the right balance. Kale grown in well-draining soil can tolerate some drought, but consistent moisture will promote healthy growth and prevent wilting. Mulching around the plants can also help retain moisture and regulate soil temperature. By watering your kale deeply but infrequently, you can encourage deep root growth, making it more resistant to drought and other stressors. This will help prevent wilting and ensure a healthy and thriving crop.
