re: What type of lawn pre emergent do you use?

Sure all the Fertilome products are good, including their Dimension pre-emerge product. What I like about Dimension is that it also has some post-emergent control of very young crabgrass giving it a slightly broader window of application but that only applies to the spring application.

I do now use the Lesco brand of Dimension (sold at SiteOne Landscaping Supply) only because you get 50 lbs of product compared to 30 lbs of Fertilome product for about the same price, but the active ingredient dithiopyr is the same in the same concentration.
