Usually during the months of September and October, we will start to see warnings for the first frost of the season.
What does a frost warning mean?
Generally, a frost warning means that temperatures will dip down into the 30s, creating an icy frost on plants, grass and cars.
What happens during the first frost of the season?
- Annuals will finish for the season. Many plants will turn brown, including their leaves and flowers.
- Vegetables in the garden will finish for the season.
- Some hardy flowers, like mums, will survive the first frost. They usually survive until a hard frost occurs, when temperatures dipping into the twenties.
One positive result of the first frost is that mosquitoes will not survive the cold temperatures.
What should you do to prepare for the first frost?
- Cut your final batch of flowers and put them in a vase indoors.
- Harvest all of your vegetables. This includes tomatoes, corn, and cucumbers.
- Cover any plants which you want to keep growing.
What can you do to extend your growing season?
If there will be just one or two nights with low temperatures expected, you may want to consider extending your growing season.
- Bring potted plants indoors.
- Cover up flowers and vegetables to protect them from the frost. In the past, we have used sheets, lightweight blankets and even a tarp. Large pieces of plastic and brown paper bags will also work, if there isn’t any wind.
