I never used this site before but thought I would give it a try. Free shipping and it came pretty fast. I don't know much about fertilizer but it did what I wanted. Made my grass grow and got rid of the weeds for a reasonable price. I will definitely use this company again. Did I mention FREE SHIPPING????
People like to say that centipede doesn't require fertilizer. It may not require it, but it likes it (long as you don't overdo it). I'm guessing some of those people may have had a bad experience with chlorosis (yellowing) due to lack lack of iron, or too much phosphate (middle number in fertilizer). This stuff is great in both regards; contains zero phosphate and adds iron! And that iron seems to allow it to flourish in a little higher ph than ideal. Result is that in one area of my lawn that unfortunately contains a mix of centipede and a bermuda hybrid, both ate growing well in about a 6.5 ph.
