Grow tomatoes by seed! Besides finding them a fraction of the cost of grocery-store tomatoes, you can experiment with all kinds of delicious flavors.

I grow beef-stakes, grapes, hollow ones and plenty of heirlooms to eat fresh and freeze as salsa and tomato sauce for winter.

Tomato Varieties to Grow From Seed

I grow oddities and heirlooms and have learned by experience the tricks of starting tomatoes from seed.

Colored cherry types are my passion. I’m planting Texas Wild (a pea-size red heirloom), Solid Gold golden grape, Aunt Ruby’s German Green cherry, Super Snow White cherry, Tumbling Tom cherry and Chocolate cherry. All should be prolific.

It’s always fun to grow a few heirlooms. I’m growing Pineapple, Schimmeig Stoo, Amish Paste and Japanese Black Trifele. Plus, I’m experimenting with several blue tomatoes. Those should be interesting, and I will share photos of them with you later in the season.

Schimmeig Stoo is an heirloom that is hollow, pleated and packed with taste.  It’s great for stuffing with cottage cheese or tuna salad.  You can’t buy it at store, but you can start plants from seed.  Photo by Doreen G. Howard

Sowing Tomato Seeds Indoors

Tomatoes are a warm season crop, so setting seed flats or pots on a heat mat promotes rapid germination. Once seeds are up, I remove the heat source, but keep grow lights two inches from the plant tops. I have to adjust the distance every other day.

The reason they grow so rapidly is that I use mycorrhizal fungi inoculants when I press seeds into the planting mix. Simply dampen seeds and roll them in the powder. Fungal hyphae or threads form on plant roots almost immediately and gather extra nutrients and water to fuel development.

I also run a small oscillating fan, directed at the plants. The constant movement triggers the release of hormones that build thicker stems. The resulting tomato transplants end up stockier than normal with sturdy stems, which are more durable when set into the garden bed. You won’t have leggy plants and you’ll avoid diseases and rot by having to bury long, thin stems.

Other warm-season vegetables such as melons, peppers and eggplant should be started from seed in the same manner. Add a bit of Epsom salts to the potting mix you use for peppers to give emerging plants an immediate dose of boron, which they crave. Plants will bloom faster in the garden and produce more peppers.

Save your eggshells, too, for when you transplant tomatoes into the garden. Crush them, scatter over the soil and then set in plants. The shells gradually release calcium into the dirt, preventing blossom-end rot. Calcium also helps all types of transplants produce vigorous root systems, spurring plant growth.
