Cultural practices

Weeds are a major problem in Marigold farming, hence 3 to 4 manual weeding during the entire growth is required.Mites and aphids sometimes infest the plants. Pests such as leaf miners or spider mites can also be a problem. This can be controlled by suitable application of insecticidal soap, repeated every other day for a week or two. Marigold plants can be susceptible to gray mold, bacterial leaf spot, powdery mildew, and root rot. Proper care should be taken.
