Dollar Weed Control with Sugar: Organic Program Requirements

Question

Bob has dollar weeds throughout lawn. Asks how often to apply sugar and if only on weed areas.

Answer (Charlotte)

Critical Condition

Sugar only works with full organic program. Chemical fertilizers kill the microbes sugar feeds. You'll revert to square one.

How It Works

• Sugar feeds beneficial microbes → enrich soil → weeds (which love poor soil) can't thrive.
• Rich soil favors desirable plants; weeds germinate but die quickly.
• Chemical fertilizers paradoxically feed weeds; natural nutrients don't.

Application

• Whole lawn, not just weed spots.
• Spring and fall (1 lb/250–300 sq ft). Water in well.
• Microbes work year-round if not killed by chemicals.

Commitment

Switch entirely to organics. No chemical fertilizers, weed killers, insecticides, fungicides. Sugar feeds the system that maintains itself.
