Why Crabgrass Killers Fail and an Organic Alternative Using Sugar

Chemical Failures

Post-emergent crabgrass killers (like Scott's) often damage surrounding turf and don't prevent next year's seeds. Crabgrass thrives in poor soil.

Sugar Program

1. Broadcast sugar at 1 lb/250–300 sq ft now; water in.
2. If winter fertilizing, apply fertilizer first, then sugar, water together.
3. Next spring: skip fertilizer, just sugar.
4. Mow high (2 in spring, 3 in summer).
5. Water deeply (6+ in) only when top 2 in are dry.
6. Use asparagus cutter to remove large crabgrass plants manually.

Soil microbes fed by sugar enrich soil; weeds decline over 3–4 years. Fertilome Lawn Food with Iron outperforms Scott's if fertilizer is needed.
