  • Grow Medium: use a medium with good draining capabilities to drain out excess water.  If using cocopeat, mix it 40% with gravel or clay pellets to ensure good drainage.
  • Seeds: use fresh, quality seeds, as old seeds may not germinate. (Note: whole seeds will not germinate well, so the seeds are split into halves before sowing for good germination)
  • pH: 6-7, almost neutral pH. Check for soil and water pH before use
  • Spacing: If you want, go for spacing of 20×15 cm or place them 1cm deep randomly and cover with the soil/media.
  • Watering: it is important to keep them moist always, but do not over water. Never dry out the plants as it leads to faster bolting of plants.
  • Fertilizers: it needs nitrogenous fertilizers which are high in Nitrogen content and low in Phosphorus. CG Greens can be a good nutrient for growing Cilantro.
  • Pest and disease: Pests like aphids and leafhoppers can be seen. Go for neem oil sprays to control them. A fungal disease may be noticed if plants are over watered.
  • When and how to harvest: Plants will be ready to harvest by 30-40 days after sowing. You can harvest the whole plant once or can cut and use only leaves from the base of the plant. Best flavor comes from the younger leaves. Snip off the flowers as and when you notice so that plant will give you some more green leaves.
