Tomatoes are one of the most popular home garden plants, and for good reason. Homegrown tomatoes are flat-out, hands-down, guaranteed more delicious than any tomatoes you can buy. You can grow your favorite kinds and harvest them at the peak of ripe juiciness. Plus, they’re truly easy to grow—for any level of gardener.

A Planting Primer 

Plant tomato seedlings as soon as the last chance of frost has passed and you’ve had a short stint of warm weather (around 50 degrees for a week or so). If you want to start tomatoes from seed, do it indoors under grow lights about eight weeks before your last frost. Visit your local nursery for organically grown seedlings, or purchase seeds from a reliable seed source such as Seed Savers Exchange.

Choose a growing spot with loose, fertile soil that gets plenty of sun all summer. Raised beds allow you to fully control the quality and content of your soil. Set tomato plants, along with a scoop of compost, into holes about 18 inches apart in each direction. Bury plants so only the top few sets of leaves are above ground (even if a lot of the stem is buried), then tamp the soil down gently around the stem and cover the base with thick mulch. Unlike most vegetables, tomatoes prefer to grow in the same place every year, so plant in the same spot unless you have had a disease problem.

Companion planting can help tomatoes grow. Tomatoes are compatible with chives, onion, parsley, marigold, nasturtium and carrot. Planting garlic between tomato plants can help protect them from red spider mites, and planting stinging nettle near tomatoes improves their longevity after picking.

Tips for Success 

Tomato plants require a lot of nutrition, so they benefit from regular applications of organic fertilizer. (Follow label instructions.) If the sky doesn’t water your plants every few days, water gently and generously at the root zone.

It’s important to stake tomatoes so they are supported as they grow upward. The easiest and most popular staking tools are wooden or wire cages. Vigorous plants may also need a tall pole for support along the central stem. Secure the stem to the pole with loose cloth or wire every 8 inches or so. Check plants regularly for tomato hornworms (large, green-and-white-striped caterpillars) and pick them off and destroy them when you see them.
