Water lightly every 1-2 days for the first 2 weeks, then switch to deep, less frequent watering.

First 2 weeks: Light water every 1-2 days
After that: Deep water 1-2×/week
Keep: Moist, never soggy

A just-transplanted tomato has a root ball only a few inches wide — it can't use water stored deeper in the bed yet. For the first ~14 days, keep that small root zone consistently moist with light waterings every 1-2 days.

After two weeks, roots have pushed into surrounding soil. Switch to the established-plant schedule: deep watering 1-2× per week. Re-run this calculator with stage set to "Established".

Why

✓Small root balls dry out quickly even when the surrounding bed is moist.
✓Frequent light water now encourages establishment; deep infrequent water later builds deep roots.

When this doesn't apply

→Heavy rain counts: skip a session if the top 2 inches are already moist.
→Wilting in afternoon heat right after transplant is normal; judge by morning appearance.

How this was calculated

1. Base water need1.25 in/week
Tomato: 1-1.5 inches of water per week (extension guidance); midpoint used
2. Transplant rule
Newly transplanted seedlings have tiny root balls. Keep soil consistently moist (not soggy) for the first 1-2 weeks, watering lightly every 1-2 days, then transition to deep, less frequent watering.
