Sugar as Lawn Fertilizer? A Sweet Myth That Doesn't Add Up

Internet rumors claim sugar feeds soil microbes and starves weeds by locking up nitrogen. The logic collapses under scrutiny: your lawn grass needs nitrogen just as much as weeds do. Depleting soil nitrogen weakens the turf you're trying to grow, creating openings for more weeds.

No university research supports sugar as a fertilizer or weed suppressant for lawns. Stick with proven nutrition—soil-tested, balanced fertilizers applied at the right rate and time. Sugar belongs in the kitchen, not the spreader.
