STA Green - Lowes fertilizer

On the other hand StaGreen has the best cheap 10-10-10 I’ve ever seen for my high PH soil

nitrogen source is ammoniacal nitrogen, plus sulfur. Also has relatively small prills and breaks down quickly after irrigation. A couple of ‘rocks’ in the bags I bought, but I’ll take that for 24 bucks.

I have used Sta green on my tttf lawn on Maryland's eastern shore for the past three years. I used their 29-0-5 general purpose fertilizer with 2% iron. That was until last fall when i switched to their natural 16-0-10 with the kelp and humus and I think iron as well. I used it again this year during the last week of March and i have to say i did not see the green up I was hoping for. I wound up using the general purpose 29-0-5 at 1/2 the rate last week and could see the benefit by three days later. The lack of expected response from the natural stuff may be the slow release vs the 70/30 fast, slow mix in their general fertilizer. One thing I discovered was if you look under the specifications on the Lowes website there is entry that says "feed duration" and it says 28 days. On the bag it says apply 4x a year no mention of the 28 day feed duration. I see most fertilizer say, feeds for up to 3 months. Don't know if that 28 day feed duration has any relation to why my lawn did not green up initially as I expected but I got a better response from the general stuff. I think I might stick with that and add kelp and humus as foliar spray applications going forward!
