This is the first time I have used a Lesco product after spending the last two season using Greenview. I laid down Dimension 0.10% 19-0-6 on my lawn and my sisters about two weeks ago. Dandelions have taken over my sisters lawn which she claims never happened when she used Scotts. I continue to have some problems with several broadlead leaf weeds (spurge*, carpetweed*, chickweed*, wild onion, and a few dandelions; *I think that's what they are). I was under the impression that the Dimension was a weed and feed. My dealer said that I could put my second application of 0.10% 19-0-6 in May, but that if the weeds were bad I may have to do 0.15% 19-0-6. He gave me a program that states to use Momentum 0-0-8 as needed. Now this is all greek to me. I don't want to break my bank doing this. Are they just being salesman or do I have to continue to dig deep in my pockets. What should I do?
