Although it may be hot and steamy now, summer won’t last forever. And if you’re deep into the gardening trend like millions of others, you know how you feel about your plant babies: You love them so much, and it’s tough to say goodbye to them at the end of the season! Luckily, you can extend the growing season by protecting your plants from unexpected cold snaps or early frosts. There’s just one tiny caveat: “Some plants aren’t suited for cooler weather,” says Jen Goff, associate product manager of tools and supplies at Johnny’s Selected Seeds. “Warm weather crops such as tomatoes, peppers and eggplant respond not only to temperatures, but to light. Once the days start to shorten, their growth and vigor also decreases.”
That doesn’t mean you can’t try to eke out a few extra weeks from your garden anyhow. If you hear that an early frost or a hard freeze is coming (apps such as Accuweather are helpful for this), there are steps you can take to provide some insulation, which may save your plants for a little longer. Many of these tips aren’t scientifically proven—and there’s always risk when nature is involved—but it’s certainly worth experimenting, which is how you keep learning, says Goff. And trust us: There’s always something new to learn about gardening!
