What is everyone's opinion as far as the best form of PreM for landscape beds? Surflan? Snapshot? XL2G? I read something about a new Dow product called Showcase.... anyone use this or familiar with it? We are simply trying to solidify on a pre-m program for some of our commercial props, and would value any input. We have used snapshot, XL2G and surflan, but at various properties and with not enough consistency. Thus we want to get set on at least 2 products and formulate a program based on that. Also, do you feel liquid over the top is better vs granular? Thanks in advance for your input!
