Neem oil can enhance the growth of kale as it acts as a natural fertilizer, promoting the development of the plant's root system. Neem oil also possesses insecticidal and fungicidal properties that help protect kale from pests and diseases.
The dosage of neem oil on kale depends on the oil concentration and the method of application. Generally, it's recommended to dilute the oil in water and spray the plants with it. The concentration of the oil can vary depending on the purpose, but a common concentration is around 0.5 to 1% oil in water.
It's important to note that neem oil should not be applied directly before harvesting, as it can leave residues on the plants. It's also advisable to test on a small portion of the plant before applying it to the entire plant to check the plant's sensitivity to neem oil.
By applying neem oil to kale, you can prevent pests such as cabbage worms, cabbage flies, whiteflies, and various types of aphids that can damage the leaves and heads of kale.
Neem oil can help control various diseases that affect kale, such as leaf blight, rust, bacterial blight, black rot, and other fungal infections. It can also assist in controlling pests like cabbage flies, cabbage caterpillars, and aphids, which are common kale pests. However, it's important to note that neem oil cannot completely eliminate pests and diseases; it only aids in their control.
