ROCHESTER, MN – Tim Olson, a dedicated gardener from Rochester, Minnesota, has spent years tending to his backyard vegetable patch. But in a few weeks the temperatures will drop, and Tim will be facing a familiar foe: frost.
“I’ve got peppers, tomatoes, and some late-blooming flowers still going strong,” Tim explains. “But every year when the frost warnings come in, I know I need to act fast, or all my hard work could go to waste.”
Tim, like many other Midwestern gardeners, has been monitoring the weather reports closely. With his crops still thriving, he’s doing everything he can to prepare for the first freeze of the season.
Frost Protection for Your Garden: Simple Steps to Save Your Plants
As the weather starts to cool, gardeners need to be on alert for frost warnings. When temperatures drop below 32°F, many plants are at risk, especially those that are tender and sensitive to cold. A moderate freeze with temperatures between 25°F and 28°F can be particularly harmful to vegetation.
For gardeners like Tim, protecting plants is essential to preserve those last few harvests.
Protecting Your Plants
Some plants, like geraniums, begonias, impatiens, peppers, and tomatoes, are especially vulnerable to frost. Taking action before the temperature drops is crucial.
Here are some key steps you can take to protect your plants:
Cover plants
Use frost cloths, newspapers, straw, old sheets, or even evergreen branches to insulate plants. Be sure to avoid using plastic covers, as they can trap moisture and cause damage. Cloth sheets are a better choice because they allow for air circulation while keeping the heat close to the plants.
Timing matters
It’s important to cover your plants well before sunset. This gives them the best chance to retain heat as the evening chill sets in. In the late afternoon or early evening, water your plants lightly to add extra moisture, which helps prevent frost damage.
Mulch wisely
Mulching can provide insulation, but be sure to pull the mulch away from the roots to avoid suffocating them.
Morning care
Don’t forget to remove the covers by midmorning to prevent overheating as the day warms up.
Tim is already taking these steps. “I’ve got my old sheets ready,” he says with a chuckle. “I cover the whole plant to keep that heat in. The trick is getting them covered in time before the temperature really drops.”
Extending Your Gardening Season
In fall, the first frost is often followed by several frost-free days. By covering your tender flowers and vegetables on frosty nights, you can extend your gardening season and enjoy fresh produce or blooms for a few more weeks.
For root crops like carrots, parsnips, beets, or rutabagas, you can even allow them to overwinter by spreading a heavy layer of newspaper over part of the row, topped with fall leaves to prevent freezing.
For Tim, this advice is key: “I’m hoping to get a couple more weeks of peppers if I can just make it through any cold nights,” he says. “Every extra day counts at this point.”
Helpful Tips for Predicting Frost
When the weather forecast mentions frost, there are a few factors you can consider to gauge the likelihood of it happening in your garden.
Temperature during the day
If daytime temperatures reach 75°F in cooler regions or 80°F in warmer climates, the chances of a frost occurring that night are slim.
Wind conditions
A windy night reduces the likelihood of frost. Wind stirs the air, preventing cold pockets from settling. However, a still night can allow cold air to pool near the ground, increasing the risk of frost.
Cloud cover
Clouds act as insulation, slowing down the cooling process. If clouds are present, the risk of frost is lower.
Landscape features
Gardens on slopes or higher ground tend to avoid frost, while low-lying areas are more vulnerable. Cold air sinks into valleys, so if your garden is in a lower spot, it may be more at risk.
Dew point
A dew point above 45°F indicates there’s enough moisture in the air to prevent frost. If the dew point is low, you may want to water your garden a day or two before frost is expected to help keep the air moist.
The Future for Tim Olson’s Garden
As the colder nights set in, Tim is doing everything he can to keep his plants safe. “I’ve been watching the wind and clouds, and I’m crossing my fingers,” he says. “This is the age old song and dance of life in Minnesota.”
For now, Tim’s late-season tomatoes and peppers are still thriving, and he’s optimistic about getting a few more weeks out of his garden.
“I’ve done all I can,” Tim says, standing next to his plants. “Now it’s just up to the weather, but I’m ready.”
