I've been watching the strong tides of opinion concerning mulches wash back and forth across my screen, and I find it fascinating. I can imagine a dinner party where mulch fanatical guests come to blows over the consumme. "Now, remember, dear, no discussion of politics, religion, or mulches at dinner tonight!" (I exaggerate, of course: things have been quite civil here compared to some of the sieges on the AOL Tomatoes board....) I have several nonpartisan questions--at least I think they are! This year (my first year of serious gardening) I learned of mulching with grass clippings. About 2/3 of my garden was heavily mulched with them, and this portion of the garden did far better than the rest in weed suppression, water retention, and general plant lustiness and health. I also have a very successful composter that I built out of hay bales. Oh, and I'm in Zone 6, in the Hudson River valley. This is the background to my questions: 1) I was wondering what to do with the composter hay bales (which have somewhat decomposed in the course of the summer) over the winter. Would there be any advantage to breaking them down into leaves (books) and covering the beds with them? Wouldn't they break down further over the winter, and thus enrich the soil? Then I could till them in before planting next spring. 2) Are there any advantages to hay composting over grass clipping composting? The weed issue doesn't particularly concern me, as any good, thick mulch would prevent the growth of weeds, wouldn't it? I lean towards grass clippings because they're abundant, free, and are proven to work in my garden, but I'm open to new information! 3) If the hay bales were going to introduce weed seeds, wouldn't they have done so in my composter? My ever healthy bindweed nemesis certainly liked to take root there, but I didn't see other weeds in the compost, and I regularly pulled hay from the top down into the compost as one of my browns. 4) This is just a general query. Doesn't anyone have any aesthetic objections to bright colored plastic mulches? Unless one's gardening is heavily scientific, or totally production oriented, isn't the sight of glaring orange underpinnings to the plants displeasing to anyone else but me? A friend gave me some of the orange plastic, I put it around some tomato plants, and within a week pulled it off. Thanks for any and all thoughts about these questions-- Aulaire
