Growing notes

Tomatoes are heat-loving plants that require a long, frost-free season and full sun. Transplant outdoors after all danger of frost has passed and the soil has warmed.

Harvest signs

Iowa State Extension

Harvest fruit when they have reached a usable size and color. Pick carefully from the plant when the entire fruit is a uniform color. When ripe, the fruit will be slightly soft to the touch, rather than firm or hard like unripe green tomatoes.

Colorado potato beetle: larvae and adults feed on leaves
Aphids: can colonize tomato plants in large numbers. You may notice leaf curling, discoloration, and sticky leaves
Sap beetles: feeding in the fruit if tomato fruits are already damaged
Tomato hornworm: large caterpillars that feed on leaves and fruit
Common diseases · 4
Early blight: causes leaf spotting and occasional fruit rot

Common questions

How much water does tomato need?

Tomato is fairly drought-tolerant once established and can dry out further between waterings. A soil-moisture range of about 35–55% is plenty — overwatering does more harm than a little dryness.

Can I grow tomato in a raised bed or container?

Yes — tomato does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.

Does tomato come back every year?

No — tomato is an annual. It completes its life in one season, so you replant it each year.
