Sugar on the Lawn: Application Rate, Safety, and Weed Suppression

A reader asks how much sugar to use, how to apply it, and if it's safe for garden beds with daisies and other plants.

Rate and Method

• 1 lb sugar per 250–300 sq ft.
• Broadcast by hand (like feeding chickens): tuck bag under arm, walk and scatter in sweeping motion for even coverage.
• Apply everywhere—lawn, garden, flower beds.

Why It's Safe

• Unlike fertilizer, excess sugar won't burn plants; it just dissolves.
• Won't harm any plants, including desirable flowers.
• Can even suppress weeds like poison ivy (apply fall and spring).

Bonus: Forgiving Timing

If you can't water immediately after applying sugar, no harm done—unlike fertilizer which burns. Only risk is wind blowing some away.
