Water deeply, not often
Deep, infrequent watering grows deeper roots and more drought-tolerant plants than frequent shallow sprinkling. Most vegetables need 1–1.5 inches of water per week — from rain or irrigation. A rain gauge tells you what nature provided. Water the soil, not the leaves — wet foliage invites disease, especially in Georgia humidity.
Tips
- • Water in the morning — leaves dry by midday, reducing disease.
- • Drip irrigation or soaker hoses put water at the root and save 50% vs. sprinklers.
- • Mulch reduces evaporation by up to 70%.
Rainwater harvesting
A 1000 sq ft roof sheds 600 gallons per inch of rain. A 55-gallon rain barrel fills in a single storm. Use rainwater for non-edible crops or irrigate the soil — not overhead on leafy greens — if you are unsure of roof contaminants. Georgia allows residential rainwater harvesting; check local rules for larger systems.
Tips
- • Cover barrels with screen to exclude mosquitoes — they breed in standing water.
- • Elevate the barrel on blocks for gravity flow; a hose needs 2+ feet of head.
- • Disconnect and drain before a hard freeze, though Georgia rarely sees them.
Drought and heat planning
Georgia summers bring dry spells and 95°F+ heat. Choose heat-tolerant varieties for summer: okra, southern peas, sweet potatoes, Malabar spinach. Mulch heavily. Shade cloth over fall seedlings in August can cut water use by a third. Accept that some crops (lettuce, broccoli) will not produce in July — plant them in spring and fall instead.
Tips
- • Water before a predicted heat wave — stressed plants recover poorly.
- • Group plants by water need; put thirsty crops together near the spigot.
- • Crimson clover as a summer cover survives drought and protects soil.
