Yesterday we talked about frost and freeze a bit. Let’s continue that discussion with some things we can do to protect our plants when a frost is predicted.
While some plants are not really affected by a frost, there are measures we can take to protect the ones that are, primarily vegetables and flowers that are sensitive to frost.

For plants that are in pots, perhaps the easiest thing to do is to move them into a protected area, such as a garage or shed.
If it’s not feasible to move the plants, the best approach is likely to cover them with a cloth sheet or row cover. Often, this is enough protection from a light frost. You would want to cover them the night before, when frost is forecast or conditions indicate a frost is possible. Remember to stay tuned to the weather forecasts. It’s generally not a good idea to use plastic as a cover, as it may not provide enough insulation and may even cause damage if it is in contact with the foliage; it may hold moisture against the plant, causing more serious freeze damage to the plant.
Some other materials that might be used are cardboard boxes and drop cloths. Whichever you use, it is best if the covering goes completely over the plant all the way to the ground, to hold the heat in.

Doesn’t exactly illustrate my point, but it’s too cute and I couldn’t resist!
Another thing that people do to protect their plants is to water the area around the plant the night before. The wet soil will release moisture into the air, which will raise the temperature. I’ve not tried this one myself and somehow, I think I might still prefer covering the plant, even if I used the watering method too.
Don’t forget to remove the covering the next day when the temperature has risen sufficiently.
Just remember that these measures will not provide enough protection if there is an actual freeze.
These are just a couple things I’ve tried myself or heard of other people doing. Do you have any other ways you protect your plants when there is frost in the forecast?
