Plant your tomato variety suited for the warm season in trays. Keep the soil warmth of 60 degrees F and above for healthy root growth.

  • No portion of fertilizer.
  • Neutral pH.
  • Porous property.
  • Good water-holding capacity.

Indoor tomato plants require daily watering. You can spray water in plant trays using a plastic spray bottle. 

Give your soil medium some time to absorb the given water in trays, and then sow the tomato seeds in it.

Seeds should be buried to ¼ inch deep, roughly 1 inch apart in the soil.

Provide bottom holes to the trays to enable air circulation and water outlet. 

If the place is cooler than 60 degrees F, warm your water up to 75 degrees F to facilitate the germination of tomato seeds. 

For Outdoors

Before you transplant your beautiful tomato plants directly under the sun, provide them an equal amount of shade and sunlight for 15 days. 

After 15 days, transplant them in raised beds of soil. Provide the tomato plants with six to eight hours of sunlight daily. 

Amend the soil with an equal portion of sand, manure, and organic fertilizer. 

Encourage good water drainage in the container or the garden. 

Spring rains provide an adequate amount of water to the soil. If rainfall is not up to the required amount, water your plants with your hands or use a drip irrigation system after every 3-5 days.
