Jury is still out
My yard is 21K sf. It’s not exactly cheap to use these products. A few spots in my front yard were showing a little heat stress before applied humic 12 and micro green. Fast forward two weeks and it does look better…but it could also be the 6 inches of rain we’ve gotten. So, jury is still out. Bottom line, it might not be helping too much but it sure isn’t hurting. Questions, is that enough to keep investing in it? If you have a little yard, I’d say go for it, what have you got to lose besides money! But for a big yard…you might be better off spending the wheelbarrows of cash on something with more direct impact…like humid coated urea.
