My Lesco dealer recommended the liquid momentum to deal with my broadleaf problem. At $60 a gallon that is a bit steep for me. I realize that gallon would probably last me a very very long time but it's still a lot of money. Are there cheaper but as effective alternative or should I just shell out the money? He did say that I could get in a granular form for $30 but I recall reading somewhere that the granuals are not as effective as the liquid. Any suggestions?
