OK guys- I know there some previous threads on this. HOWEVER, wanted some more insight. I picked up a few additional properties this year and all have SERIOUS crab problems. Some nutsedge too, but not as bad as the crab. Id like to do one app and get season long control. Ive read that Dimension may not last as long as Barricade. I like the Nutrients Plus products and have been very satisfied w/ the Speedy Green. Any insight is much appreciated!
