Follow these steps to speed the growth of your Marigold

  • Use earthen clay seedling trays or pots. The first and most important step for good plant growth is healthy seedling. It is best possible in earthen pots.
  • Use quality soil mixture with little anti-fungal powder. The best possible mix for Marigold is 30-30-30 % mix with an equal amount of garden soil, coco peat with vermicompost.
  • Don’t overwater the plants. It is the main reason for root rot and plant death. Watering should be done only when it is required the most.
  • Avoid chemical fertilizers. The inappropriate use of chemical fertilizer is the main reason for seedling and plant decay. So I recommend using only organic fertilizers in 10-15 days gaps.
  • Separate single seedlings. For best growth, it is recommended to separate seedlings when they are of 4-inch height i.e., about 8-10 cm.
  • Don’t put seedlings 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.
  • A final but most important tip for faster bloom is to put the new plants in direct sunlight. At least 6-8 hours of sunlight is required for faster blooming in marigolds.
