Plant

Bury transplants deep — up to first true leaves. Roots form along buried stem, making a stronger plant.

Care

Cage or stake at planting. Pinch suckers on indeterminates. Consistent water prevents blossom-end rot and cracking. Mulch heavily.

Harvest

Pick as they color up; ripens fully off the vine on a windowsill.

Preserve

Sauce, paste, whole canned, salsa, sun-dried, frozen whole for winter. The whole plan revolves around this crop.

Companion planting

What tomatoes likes, and doesn’t.

Good neighbors

Avoid nearby

  • Cabbage family
  • Corn (same earworm)
  • Fennel
  • Kohlrabi
  • Potatoes (shared blight — never same bed)
  • Rosemary

Basil + tomato is the classic pairing — improves flavor AND repels tomato pests. Mature dill stunts tomatoes; young dill is fine.
