Marigold cultivation can be done in various types of soil. Soil with good drainage, such as sandy loam, is suitable for zinnias. Marigolds grow well in soil with a pH level between 7.0 to 7.6. Adequate sunlight is necessary for marigold crops. For better germination of seeds, the temperature should ideally range between 18 to 30 degrees Celsius. Prior to sowing, seeds should be treated with a fungicide such as Thiram, Captan, or Bavistin. Seeds should be sown at a depth of approximately 15-25 mm above the ground level.
Preparation of Marigold Plants: Marigold plants can be prepared in nurseries and then transplanted into fields. The width of the beds is maintained at 100-120 cm. During bed preparation, well-decomposed cow dung manure or compost should be mixed at the rate of approximately 5-8 kg per square meter. Seeds should be sown in lines, leaving a gap of 6-10 cm between two lines. The seeds should not be sown too deeply, with a depth of 1-2 cm, and should be covered with soil, sand, or compost. Regular watering is essential, as required. Marigold plants are ready for transplantation in fields within 20-25 days.
