Tomatoes: Picking a Variety, Timing It Right, and Transplanting Without Setback

By Growing Home Greens Team · July 23, 2026

Tomatoes are in almost every vegetable garden, and three decisions end up mattering more than anything on the seed packet: what type you plant, when it goes in the ground, and how you handle the move from pot to soil.

Picking a variety

Skip the variety name for a second and look at the type. Determinate tomatoes grow to a fixed size and ripen most of their fruit in a short window, then they’re done — good for canning, not great if you want tomatoes trickling in all summer. Indeterminate tomatoes keep growing and setting fruit until frost kills them, which is what most people actually want, but they need real support: a tall cage or trellis, not the flimsy wire cone from the garden center.

Beyond that, it’s mostly about what you’re using them for. Beefsteak and slicing types are for sandwiches. Paste and roma types have less water in them, so they cook down into sauce faster. Cherry and grape types are the easiest to grow and the fastest to produce, which makes them a good first tomato for a kid or a beginner. Heirlooms usually win on flavor; hybrids are usually bred for disease resistance, which matters if blight has wrecked your plants before.

We keep specific variety recommendations — the ones backed by an actual source, not just a name we like — on the tomato growing profile instead of repeating them here.

When to plant

Tomatoes don’t handle frost, and almost nobody direct-sows them outdoors. The general shape is: start seeds indoors about 6 weeks before your last spring frost, then transplant outside about 2 weeks after that frost date, once nights are staying above 50°F. Cold soil will stall a tomato even on a warm-feeling day.

That’s a rule of thumb, not your actual dates — frost timing swings by more than two months across USDA zones. The planting calendar and your zone’s tomato page will give you the real dates, and the Garden Designer times every plant you place the same way.

If you missed the indoor-start window, a nursery start works fine — the plant doesn’t know or care whether you grew its first six weeks or someone else did.

Transplanting without setback

Plant tomatoes deeper than they sat in the pot. Pinch off the lower leaves and bury most of the stem — tomatoes grow roots anywhere the stem touches soil, so a deep-planted, slightly leggy seedling ends up with a bigger root system than one planted at its original soil line.

Harden the seedling off first: over a week or so, set it outside for a little longer each day, starting in shade and working up to full sun, before it goes in the ground for good. Skip this and a healthy indoor seedling can go pale and droopy within days outside. Transplant on a cloudy day or in the evening rather than midday sun, and water it in right away — that settles the soil and closes up air pockets around the roots.

Put the cage or stake in at the same time you transplant, not weeks later. Driving stakes in around a plant that’s already spread out risks the roots, and training an established plant onto a cage is harder than growing it into one from the start.

Once it’s in, check the companion planting guide for tomatoes for what to plant nearby — basil and marigolds are the classic pairing, corn and cabbage are the ones to keep some distance from.
