seems that most people on here dont use any type of fabric to keep weeds out when putting down mulch. i always do. one of my new lawn customers had a very large and reputable landscaping company put in some major landscaping(about $50, 000) they went with all mulch(about 30 yds), the work is less than a month old and already there r weeds, millions of them. dont the customers complain about this? what do u tell them? i know u can use a pre-em, but in may or june its kinda late for that i think.
