While i was outside this afternoon digging out great quantities of grass and other assorted weeds from one bed, i began to contemplate my decision to start mulching. The weeds and grass are overwhelming everything, including me. I have always tried to be as organic as possible, but i've now resorted to weed killer in some spots. :(
Anyway, i have some questions about mulching. The number one question is, if your perennials come up through the mulch, won't the weeds do the same thing? How much mulch should a person put around established perennials, i.e., how deep? And are wood chips from trees chipped up by Ontario Hydro good enough? I've used them over landscape fabric and in paths, but not on bare garden soil. If i have to buy 100 bags of cedar chips or something like that, it just may influence my decision! And that's another thing - how long does mulch last in your garden? Does it have to be renewed yearly, or how often?
Thanks in advance for answers, and i'm sure i'll end up with a few more questions!
