Test your soil first
Before planting, send a soil sample to the UGA Agricultural and Environmental Services Lab. The $10–15 test tells you pH, phosphorus, potassium, and micronutrients, with crop-specific lime and fertilizer recommendations. Guessing at soil amendments wastes money and can poison your beds. Georgia soils are often acidic and low in organic matter.
Tips
- • Sample before adding anything — you cannot un-add fertilizer.
- • Take 10–15 sub-samples across the bed, mix, and submit one cup.
- • Most Georgia gardens need lime every 2–3 years to raise pH above 6.0.
Compost
Compost turns kitchen and yard waste into stable organic matter that feeds soil life. A 3×3 ft bin, kept damp and turned monthly, makes finished compost in 4–6 months in Georgia's climate. Add browns (leaves, paper) and greens (food scraps, grass) in roughly 3:1 ratio. Avoid meat, dairy, oils, and diseased plants.
Tips
- • Hot compost (135–160°F) kills weed seeds and pathogens — get the pile big enough.
- • Finished compost smells earthy, not sour; if it smells like ammonia, add browns.
- • Screen finished compost through 1/2-inch hardware cloth before adding to beds.
Cover crops and rotation
Never leave soil bare. A winter cover of crimson clover, winter rye, or oats protects soil, adds organic matter, and — for legumes — fixes nitrogen. Rotate crop families each season: nightshades (tomato, pepper) → legumes (beans, peas) → brassicas (collards, broccoli) → roots (carrot, beet). Rotation breaks pest and disease cycles.
Tips
- • Cut cover crops 3 weeks before planting — they need to decompose.
- • Legume covers can replace 25–50% of your nitrogen fertilizer for the next crop.
- • Even a 6-week summer cover of buckwheat suppresses weeds and feeds pollinators.
Mulch and regenerative practices
Mulch conserves water, suppresses weeds, and feeds soil life as it breaks down. Use straw, leaves, or compost — not dyed wood chips near edibles. Minimize tilling; disturbed soil loses structure and carbon. Add organic matter every season. Healthy soil grows healthier plants with fewer inputs.
Tips
- • 2–3 inches of mulch is enough; more can block water and shelter slugs.
- • No-till is a spectrum — even reducing tillage helps soil life recover.
- • Leave roots in the ground when you pull a crop — they feed the soil food web.
