ok, so some of my customers beds are begining to suffer from weeds, i would like to set up some programs to prevent this and was wanting to find out what works for you and if you have made any formulas work to determine pricing. we have people that are fine with round up and some that want only hand pulling. and also when weeds are growing in dense ferns and ground cover. something would be done each visit unless they didnt need anything. would like help from chemicals but not sure what to use, if it would hurt shrubs or seasonal color, for a post and pre emergent. so does anyone have different things they do for flower bed maintenance, that works well? thanks!!
