It happened while I was writing this article. Our local meteorologists forecast nighttime temperatures low enough to nip at the tender flowers and greens in our gardens...and this time, they were correct.
As always, researching this article has uncovered some good information about frost and how to best protect plants.
A bit about frost:
Unless your yard is perfectly level (lucky you), you may have noticed that frost will visit some areas of your property more (or less) than others. Since cold air is heavier than warmer air, the cold air will settle in low lying areas, such as at the bottom of an incline. Pockets of this colder air will sink down until it settles into a depression or hollow. Since it then stops moving, it may cause frost damage on plants. Other factors affecting frost are your house/garage, protective trees,
Although we don't have such high altitudes in Northern Rhode Island, in your travels you may have noticed that higher altitudes, with thinner air, experience colder temperatures which makes those areas prone to frost.
Frost protection tips to protect your precious plants:
- Water before an expected frost. Moist soil retains the heat of the day better
than dry soil.
- Cover plants with burlap or cloth...never use plastic.
- Other coverings that work well include inverted buckets, cardboard boxes, paper
bags and even newspapers.
- Don't let coverings get your plants down. Use stakes to support the weight of the covering. Know that wherever a plant touches the covering, it is less protected.
- Keep your wraps in place. Lightweight coverings should be weighted down with rocks so they don't blow away.
- Potted plants are particularly susceptible to the cold since there is little soil protecting their roots from freezing temperatures.
- House plants and tropical plants should be brought into your home for the winter or you can bury the pot in the soil and cover the foliage with burlap.
- Annuals and other flowering plants can be saved by covering them before dusk. After the sun sets, the temperature in your garden drop quickly.
- Covers must be removed from plants in the morning, before the sun hits them. Otherwise, your plants may overheat as the daytime temperatures rise.
- To warm up your plants, water them just before sunrise when the temperature dips to 32 degrees or colder. Water won't help once the damage has occurred.
- Have you seen chemical sprays to protect plants from frost? There is no commercial product that really works.
- Tomatoes are extremely sensitive to frost. Pick all the tomatoes that are in the late stage of green, just prior to ripening. Store them in a single layer, not crowded, in a dark room that is warmer than 55 degrees. They will ripen, but won't have the amazing flavor of vine-ripened tomatoes.
Of course, these are temporary measures. Eventually the temperatures will get so cold, our plants will succumb despite our best efforts. Personally, the longer I can hold onto growing season, the happier I am.

And now you cannot see the hills
