Pamela's comments on ground cloth, I'm assuming she means the woven polypropylene (but perhaps she meant the felted) and its usefulness in the greenhouse are important. I've used this (in 10 and 12-foot widths) since I started the nursery for many applications. I was delighted to see when even the local BiMart (similar to Target but more farm-oriented) started carrying 3-foot widths. The stuff is so useful. Probably the most important reason I use it is that having worked in commercial nurseries for several years, I've seen the nursery dogs - often larger breeds like German Shepherds - spend years running around on 3/4 minus gravel typically used everywhere in a nursery. The consequence is that these dogs by the age of six or even earlier become crippled with arthritis. Ground cloth, even with some small gravel under it, avoids this. Plus a good corn broom works beautifully and I routinely sweep several times a year. I've not had any critters come up through it either. I don't use the felted stuff for the reasons she mentions - silt build-up. The advantage of the woven material is that weeds don't grow through it, water drains as well as bare dirt and in muddy environments which I have in spades right now, you're not tracking dirt in the house and it gives you a better footing. When I cut it, the edges ravel, so I light a candle and carefully melt the cut edge. I have pieces of ground cloth more than 30 years old where the melted edges are holding up very well. I do fold the edges and tuck them under when I drive in the 6" staples, but the longevity of this woven stuff (in my climate, anyway) is amazing. My lean-to greenhouse is about to be built so all these tips on little details are hugely helpful!
