PRUNING: Indeterminates likely benefit by removing all suckers under the first strong branch directly below the first flower cluster. For tall indeterminates, consider short extensions or pruning once they outgrow a manageable size for easy harvest. TRELLISING: Basket-weave by pounding 5–6' stakes every 2–3 plants, using heavier t-posts intermittently and at ends of beds. Water seedlings with a high-phosphate fertilizer solution at planting to help boost early yields. Plant deeply to encourage adventitious rooting. In rows 4–6' apart, space determinates 12–24" and indeterminates 24–36".
Avoid exposing unprotected plants to consecutive nightly temperatures below 45☏ (7☌). For earliest crop, plant under row cover around last frost date. Supplemental lights and lower night temps control stretching. Grow at constant 60–70☏ (16–21☌) temp and use complete fertilizer until hardened-off. At first true leaf, pot-up to 50-cell trays or 4" pots, depending on expected transplant timing. Keep mix at 75–85☏ (24–29☌) with moderate moisture. About 5–6 weeks before transplanting, sow 1/4" deep in 20-row flats with 20 seeds/row, or in 200-cell trays with 1 seed/cell lightly cover. TRANSPLANTING: Don't start too early-leggy, root-bound, or flowering transplants can cause stunting and reduce early production. Tomatoes typically germinate in 5–7 days. For short determinates, succession-plant every 4–6 weeks.
Fertilize accurately since excess nitrogen causes rampant growth, rot, and delayed ripening. CULTURE: Medium-rich soil with pH 6.0–6.8 preferred. INDETERMINATE (Climbing): Varieties should be staked, trellised, or caged, and pruned for best results fruit ripens over an extended period. You can also check out some of the many articles and plant profiles we have focused on tomatoes.SCIENTIFIC NAME: Solanum lycopersicum DETERMINATE (Bush): Varieties do not need pruning and may be grown with or without support fruit ripens within a concentrated time period. Of course we all have our favorite tomatoes, but we've put together a varied selection of excellent tomatoes you can grow in your own garden, with details about their qualities, best uses and some tips on growing. Tomatoes are not cold hardy plants, and need hot weather to really flourish, but some varieties may reseed themselves in spring, particularly cherry tomatoes. If you have a sunny spot, and a bit of space, you can grow tomatoes! Be aware that cherry tomatoes, despite their small size, grow on plants that can get very big, and most tomato plants will need staking or support of some kind. Tomatoes requires extra care but once you develop a system, they aren't difficult to grow, either in the garden or in a container (we have tips to help you with that, too). Fresh tomatoes can also be cooked and preserved easily by canning or freezing, for making healthy and delicious dishes in winter. Tomatoes are the ultimate summer treat, Tomato lovers anticipate the first fruit, ripe on the vine, because there's nothing better than a fresh local tomato sliced on a sandwich, tossed in a salad, or made into a fresh salsa.
