Basil thrives in well-draining, nutrient-rich soil. A soil mix that contains a combination of potting soil, perlite, and compost will provide the necessary drainage and nutrients. The ideal pH for basil is between 6.0 and 7.5.
Regularly check the soil’s condition and replenish nutrients by adding organic fertilizers or compost. Avoid using heavy clay soils, as they retain too much moisture and can lead to root rot.
7. Recognizing Signs of Pests and Diseases
Pests such as aphids, spider mites, and whiteflies can cause basil leaves to wilt by sucking the sap from the plant. Regularly inspect your basil for signs of pests, such as sticky residue or tiny insects on the leaves.
Diseases like downy mildew and fusarium wilt can also affect basil. Look for yellowing leaves, dark spots, or a fuzzy growth on the underside of leaves. Promptly remove affected leaves and treat the plant with organic pesticides or fungicides as needed.
