Overwatering is the number one cause of plant death in home gardens. Learning to read your soil and your plants is the most valuable skill any gardener can develop.
The Golden Rule: Water Deeply, Less Often
Frequent shallow watering trains roots to stay near the surface where they're vulnerable to heat and drought. Deep, infrequent watering encourages roots to grow downward, making plants more resilient over time.
Best Time to Water
Early morning is ideal — water has time to soak in before daytime heat, and foliage dries quickly to prevent fungal issues. Evening watering leaves foliage wet overnight, which promotes mildew and disease.
How to Know When to Water
- Push your finger 2 inches into the soil — if it's dry at that depth, water
- Wilting in the morning (not just during afternoon heat) signals underwatering
- Yellow lower leaves often indicate overwatering
- A moisture meter removes all guesswork and is worth the $12 investment
Most vegetables need 1–1.5 inches of water per week from rain or irrigation combined. Always water at the base of the plant — never overhead for fruiting crops.
