Q: I read online that you can use sugar for lawn fertilizer. It said it’s cheaper and is much better than using commercial stuff. What are your thoughts on this?

A: Not many garden questions cause me to stare at the computer screen and say “What???!!”, but your’s did!

Sugar has been touted as a weed killer because it theoretically reduces nitrogen in the soil, thereby reducing the nutrients weeds need. But your lawn grass also needs nitrogen in order to grow. I can’t find any information that reconciles these two statements. You can try it if you’ve a mind to, but I predict sugar will be no benefit to a lawn.
