Hmmmmm.. I think I made a costly mistake to one of my customers, well not that costly.. Currently I charge this DR a monthly maintenance for her property which is weeding her beds monthly for $60 a shot.. It takes me like only under 30mins to do service it! I suggested to her a bark mulch installation on her property with landscape fabric.. I know this will be like under $250 to do the whole thing! So if I do the bark mulch, I'll lose out on a monthly maint customer! I guess you can re-apply bark mulch every so often because it decomposes??!?!
