I went to home depot and thought I was buying 3 bags of Lesco Pre-Emergent fertilizer, but I accidentally picked up a brand name called All-American. It is Lawn and Garden Fertilizer 5-10-5 for lawns, vegetables and shrubs. The bag is the same color as the Lesco, and was mixed in with the Lesco! Anyway, I put it down with a Scott's "EdgeGuard" spreader at the setting of 6. It was a 40 lbs bag. The question is, what do I do now that it's on my lawn? Do I put the Lesco Pre-Emergent down which is 19-0-7 or do I have to wait until a certain amount of time has passed? The problem is, I put that bag on one side of my lawn and the correct Lesco stuff on the other side!! I know, I should have looked more closely. All American - Fertilizer (All ready on lawn): 5% Nitrogen 10% Phosphate 5% Potash Lesco Pre-Emergent(want to add to the lawn): 19% Nitrogen 0% Phosphate 7% Potash If I add it now I would have a total of: 24% Nitrogen 10% Phosphate 12% Potash Can I do it? This is a bad way to start of the season.... Thanks for your help in advance.
