Check the pot daily and water whenever the top inch is dry — about 0.5 gallons until it drains.

- Top 1 in. dry
Container-grown peppers can't reach deeper soil moisture, so the pot is the whole water supply. In a 5-gallon container, check daily; typically water every 1-2 days.
Use the finger test, not the calendar: push a finger 1 inch into the mix. Dry at 1 inch means water now, until water runs out of the drainage holes.
Why
- ✓Pots hold a small soil volume that heats up and dries out far faster than garden beds.
- ✓Peppers at flowering and fruiting stage are especially sensitive to moisture swings. Water stress during flowering causes blossom drop; uneven moisture invites blossom end rot.
When this doesn't apply
- →Self-watering containers with a reservoir: refill the reservoir instead; the 10% rule doesn't apply.
- →Cool or rainy weeks: always confirm with the finger test before adding water.
How this was calculated
- 1. Base water need1.5 in/week
Pepper: 1-2 inches of water per week (extension guidance); midpoint used
- 2. Container rule
Containers dry out much faster than garden soil. Check daily; water when the top 1 inch of mix is dry, until water runs from the drainage holes. In hot weather this often means daily or twice-daily watering.
- 3. Amount per watering≈ 0.5 gal (our estimate)
~10% of pot volume as a starting point: 5 gal × 0.10
Our estimate, derived from the cited guidance.
