Common Pests & Diseases
Like any other plant, water spinach is susceptible to pests and diseases. Here are some of the most common ones:
Aphids: These tiny insects feed on the sap of the plant and can cause stunted growth, yellowing of leaves, and the formation of sticky residue (honeydew). Use insecticidal soap to get rid of them.
Leaf miners: These larvae tunnel inside the leaves, causing white or brown trails. Use neem oil to control them.
Powdery mildew: This fungal disease causes a white powdery coating on the leaves. It can be prevented by providing good air circulation and avoiding overhead watering.
Habitat
Water spinach grows in wetlands, swamps, and other water bodies, such as rivers, ponds, and canals. It prefers warm temperatures and can grow in both freshwater and brackish water. The plant can be grown in containers and raised beds as well.
