How to Start Growing Tomato Seeds Indoors

Tomato plants are one of the easiest vegetables to start growing indoors from seeds. You need to start this process about four to six weeks before the last spring frost date in your region.

  • Tomato Seeds
  • Tomato Starter Container/kit
  • Starter Soil Mix
Simple Steps
  1. Fill a container with seed starter mix or use organic potting soil mix (I get it at Costco for fraction of the cost). DO NOT use garden soil which often drains poorly and may carry disease. Gently press the soil to remove air pockets.

  2. Use finger to poke a small hole per seed about a quarter-inch deep. Place one seed in each hole. Then sprinkle additional soil to cover the holes with seeds about a half inch thick. Once again gently firm the sprinkle soil mix and water it lightly (DO NOT flood the container with water).

  3. Place a container in a wart full light place (I place on the window sill) about at least 70 F (21 C) to 80 F (27 C).

  4. Check daily to keep the planting mix moist but not saturated. Once you see the first sprout keep the seedling to high light exposure or set on the window sill that has lots of direct sun.

  5. Continue keeping the planting seed moist but not soggy.
  6. When the seedlings are about 2 to 3 inches tall and have 2 sets of leaves, its time to transplant individual tomato seedlings into bigger pots. Read more about this process in the next post.
