The tomato is the reason most people start a vegetable garden, and a vine-ripened one is worth every bit of the fuss. Tomatoes aren't difficult, exactly, but they're demanding: they want heat, sun, steady water, and a bit of support and pruning. Give them those and a single plant can hand you fruit for months. What follows is the full arc, from planting to the first ripe slicer.

Determinate or indeterminate: decide first

Before anything, know which type you're growing, because it changes everything downstream. Determinate ("bush") tomatoes grow to a set size and ripen most of their fruit in a couple of weeks: tidy, good for containers and canning, little pruning needed. Indeterminate ("vining") tomatoes keep growing and fruiting until frost; they need tall support and regular pruning but reward you all season. Check the tomato catalog page for the variety you have.

Plant tomatoes deep, in full sun

Tomatoes need at least 6–8 hours of direct sun and warm soil. Wait until nights stay reliably above 55°F, ideally closer to 60°F, since fruit set suffers below the mid-50s, well after your last frost date. When you transplant, use the tomato's special trick: plant it deep, burying two-thirds of the stem. Tomatoes grow roots all along a buried stem, so this builds a far bigger, stronger root system. Space them generously for airflow, and water in well.

Support and prune as they grow

Get a stake, cage, or trellis in place at planting, before the plant needs it. For indeterminate types, pinch out the "suckers" (the shoots that sprout in the crotch between the main stem and a branch) to focus energy on fruit and keep the plant open and airy. Determinate types need little or no pruning. Either way, keep the lowest leaves off the soil to limit disease.

Water steadily — it prevents the big problems

Tomatoes want deep, consistent watering, ideally at the base, not the leaves. Erratic wet-dry cycles are a major trigger for blossom end rot and cracked fruit, so a thick mulch to even out soil moisture pays off enormously. Feed when flowering begins, going easy on nitrogen so you get fruit, not just leaves; see how to fertilize a vegetable garden.

Watch for trouble, then harvest at the peak

Stay ahead of the classic tomato pests and disorders: patrol for tomato hornworms, and if leaves curl or yellow, work through the tomato leaf diagnosis guide. Then the payoff: pick when fruit is fully, evenly colored and gives slightly to a gentle squeeze. Get your transplant date dialed in for your location with the planting calendar, and you'll be eating real tomatoes by midsummer.
