Using Sugar on Lawns: Benefits and Insect Concerns

Why Sugar?

Sugar (especially brown sugar or molasses) feeds beneficial soil microbes—bacteria and fungi that cycle nutrients and improve soil structure. The microbes can't digest solid sugar, so water it in lightly to move it into the root zone.

Insect Attraction

Yes, sugar can attract ants, bees, and other insects. To minimize this:

• Apply in early morning or evening when foraging is lower.
• Water in immediately so sugar moves off the surface.
• Use molasses diluted in water instead of dry sugar—it penetrates faster.

Reality Check

Sugar gives a short-term microbial boost but isn't a long-term fertility solution. It's best used as a supplement within a broader organic program that includes compost, aeration, and proper mowing.
