Planting Tomato Seeds Indoors

Planting tomato seeds indoors is not as difficult as you might think. Read my simple tips to ensure your own success!

Most seed packets will tell you to plant tomato seed 6-8 weeks before the last frost.

In my gardening zone 8b here in the Pacific NW, our last frost date, is April 15th. I tend to wait until the middle of March to start planting tomato seed.

I use heat mats, along with large six cell seed starting packs in a growing tray with no drainage holes with a plastic dome cover lid.

It is very important that the seed be in contact with the soil completely around.

Then I use a spray bottle and lightly spray the seed until I know that the seed and all surrounding soil is completely damp.

It is fine to start the seed directly in Solo Cups or larger pots if you are not limited on space.

After germination and removing the plastic dome lid, place the tray under grow lights and keep the lights 1-2" away from the seedlings.

Very quickly your starts will need to be up potted to a minimum of a 4" pot. Remove the bottom leaves and bury it as deep as you can in the pot.
