Water deeply 2× per week, about 1.1 gallons per plant each time.

- Per session

Your in-ground pepper needs roughly 1.5 inches of water this week — that's about 2.1 gallons per plant. Split it into 2 deep waterings of ~1.1 gallons rather than daily sprinkles.
Deep, infrequent watering pushes roots down and keeps moisture steady. Water stress during flowering causes blossom drop; uneven moisture invites blossom end rot. Water at the base in the morning, and count rainfall toward the weekly total.
Why
- ✓Extension guidance puts pepper water needs at 1-2 inches/week; the adjustments above tailor it to your conditions.
- ✓Fewer, deeper sessions beat daily light watering: deeper roots, fewer disease problems, steadier fruit.
When this doesn't apply
- →After significant rain (½ inch or more), subtract it from the weekly total before watering.
- →Always confirm with the finger test: if soil is moist 2 inches down, wait a day.
How this was calculated
- 1. Base water need1.5 in/week
Pepper: 1-2 inches of water per week (extension guidance); midpoint used
- 2. Convert to gallons≈ 2.1 gal/week per plant
1.5 in/week × 0.623 gal/sq ft/in × 2.25 sq ft root zone
- 3. Split into sessions≈ 1.1 gal per session
2.1 gal ÷ 2 deep waterings per week
