Hi, I'm Stan De Freitas, Mr. Green Thumb. You know, when you talk about cold protection, many people have, well different kinds of covers. Now, you can buy commercial covers, but you probably have some covers right in your own backyard. You know, an old blanket, an old towel. If you've got a sheet, or something like this, just make sure you cover all the way to the ground. That may not be quite as effective as some of the materials that you buy, but it's certainly a lot cheaper. If you've got some old towels, if you've got some old sheets, make sure you cover over the plant all the way to the ground. You're going to help hold some of that energy in, and around your little plant, especially important for Tomatoes, Peppers, and Eggplants. All of those plants don't like cold. If you get anywhere near thirty-two degrees, you're probably going to have some injury. If you cover your little plant over, you may make the difference of keeping that plant alive. Your favorite Croton; your favorite Hibiscus, make sure you cover all the way to the ground, that's important. It also helps to keep the frost off your plant, as well. Covers can help keep your plants alive when it's a matter of getting too cold. For On Gardening, I'm Stan De Freitas, Mr. Green Thumb.
