This is a question i've been debating back and forth over w/ myself. Should weedwacking those nasty little weeds that grow thru sidewalk/driveway cracks be part of lawn maintenance, or should that be a separate service (maybe charge a one time fee to weedwack it all to the ground, then spray the spots real good w/ a high quality herbicide like lesco's prosecutor)? On the one hand, i am being paid to cut the person's lawn every week so you could say that that is part of maintaining some one's property, but on the other hand, sometimes u get customers who haven't maintained their property very well and the weeds are out of control. In this instance, hitting the weeds w/ the trimmer can be very time consuming and goes thru string very fast (i don't care so much about the cost of string, but rather the more frequent re-stringing the trimmers). what do u guys think? should this be included in a regular lawn mowing service? i know every one of u has been asked to "just quick hit those weeds growing thru the cracks while you're here." Well????????????????????
