I hope you all will excuse the bonehead questions about frost protection.


Heh, heh. You obviously haven't been here long enough to see all of MY boneheaded questions! But this group is very patient and very helpful. If they haven't thrown me out yet, I don't think you have anything to worry about.

Regarding frost protection, we had a long discussion about that last spring. I haven't been here too long, but I suspect that it probably comes up every year. It is, after all, a perennial bane. (You might try checking the archives.)

What I got from our discussion is that there are a variety of tactics that might or might not help, depending on how many plants you must protect and - especially - how cold it gets. If you only need a degree or two of protection, something as simple as running a sprinkler all night can sometimes help. On the other hand, sometimes nothing will do any good. Last spring, after a very warm March, temps here dropped way below freezing for five nights in a row (lowest was 17°). Nothing I did - and probably nothing I could do - made the slightest difference.

I'm just a newbie, but in your case, I'd suggest just using TWO layers of frost cloth, rather than pay to have frames built. One layer doesn't do much, especially if it's touching the plant, but two will have some air between them for insulation. If you think you need more than that, run an extension cord out to it and put an incandescent light bulb under the cloths. Or you can use Xmas tree lights, jugs of water, or anything that will provide just a little heat.

Yes, you'll have to take these off between frosts. I don't know exactly what you're trying to do. In my case, it would be a matter of delaying the first fall frost a bit (for vegetables) or protecting early growth from a late freeze. If you expect to do this all winter, it would be a LOT of work, and maybe you should think about what you're planting. Or maybe some kind of semi-permanent greenhouse structures would make more sense.

One other thing: for me, here in Nebraska, the wind is usually a factor. We tend to get colder on still nights, but it can still be windy during the day, which makes it extremely difficult to erect cloth shelters. And last April, during our cold snap, the wind howled all day and all night. Not only did it blow off almost everything I tried to use, but I don't suppose the 'two-layers of cloth' idea would work as well when the wind is whipping things around. Things are probably different for you, but I thought I'd mention it. I'm almost to the point that I'm just going to accept whatever the weather does and try to live with it. But if you just need to get past a night or two of cold weather, it might be worth it.

To repeat, though, I'm just a newbie at all this, not at all an expert. I am learning - this list has been extremely helpful - but I have a long way to go. Still, if I misled you about anything, I'm sure someone more experienced will correct me.

Good luck,
