I used it quite a bit about 8 years ago. It was fairly good. On new lawns that had not been taken care of the results were great. However, I switched to Sunniland (Sanford Florida) in 93. They offer quite a few products you won't find in the stores. They have a 16-4-8 acid/iron (3% iron and other minors)that I like alot. They also have a 24-5-11 that they have started pushing lately that works well. The prices are pretty good (50# acid/iron is around $7.00) and you can just pick it up from the plant, if you don't mind driving to the Orlando area.
