I didn't want to threadjack Matt's mulch question, but I've got a couple related questions...
I've got areas of bark mulch on non-woven fabric. The bark's about 2 years old and ready to be refreshed. Is there any reason not to simply place more bark on top of the existing stuff, of should I remove the old bark first?
Also, I've got a couple hundred feet of redwood bender board edging between the grass and planter areas. Much of it is broken from foot and paw traffic, and it's getting time to replace it. (A job I'm not looking forward to.) I can't afford to build a proper masonry mow strip right now, but want to replace the bender board this spring. Any suggested replacement materials? Rubber? Plastic? Wood again?
Thanks
