Organic Lawn Care: Sugar Instead of Fertilizer, Perennial Grasses, and Natural Weed Control

An Ohio homeowner asks when to reseed and apply final fertilizer, and whether to fertilize before or after seeding. The advisor (Charlotte) advocates a sugar-based organic program.

Why Not Fertilizer?

• Fertilizers add nutrients but kill beneficial microbes that build soil fertility.
• Nutrients leach out; microbes create lasting fertility.
• Sugar (or dry molasses) feeds microbes: 1 lb/250–300 sq ft each spring and fall, broadcast by hand, water in.

Reseeding?

Only needed if using annual grass (e.g., annual rye). Choose a perennial, spreading grass (bermudagrass spreads by runners; fescue/bluegrass are bunch types requiring thick seeding).
