Water deeply 2× per week, about 1.9 gallons per plant each time.

Your in-ground cucumber needs roughly 1.5 inches of water this week — that's about 3.7 gallons per plant. Split it into 2 deep waterings of ~1.9 gallons rather than daily sprinkles.
Deep, infrequent watering pushes roots down and keeps moisture steady. Uneven watering is the top cause of bitter and misshapen cucumbers. Water at the base in the morning, and count rainfall toward the weekly total.
Why
- ✓Extension guidance puts cucumber 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
Cucumber: 1-2 inches of water per week (extension guidance); midpoint used
- 2. Convert to gallons≈ 3.7 gal/week per plant
1.5 in/week × 0.623 gal/sq ft/in × 4 sq ft root zone
- 3. Split into sessions≈ 1.9 gal per session
3.7 gal ÷ 2 deep waterings per week
