  • Don’t put seedling directly to grow pots. First seedlings should be grown in smaller pots for proper root growth. You can use any 2-3 inch plastic or clay pots for this purpose.
  • Keep the seedlings for 10 days in semi-shaded reason. This will help them to develop new roots and a well-bound root-ball will develop.
  • After 10 days of plant, the healthy seedlings in grow pots of at least 6-8 inch diameter.
