However, with a little effort, you can indeed grow carrots. Plus, the home gardener has so many more varieties to grow from Belgium Whites to Purple Dragon to Parisian heirlooms that are round! (Not all carrots are the grocery store shape.) In fact, don’t expect to get perfectly straight ”grocery store” carrots. Your carrots will still taste better, whatever their shape!Ĭarrots have a reputation of being difficult to grow, especially in heavy, compacted soil. This popular vegetable has a natural sweetness-especially the homegrown carrot because the sugar that makes a carrot sweet begins to be replaced by fiber as it ages in the grocery stores. They are an excellent source of vitamin A and add color to a meal. Here’s what you need to know in order to grow carrots in your garden! About CarrotsĬarrots are a cool-season crop grown in spring. The trick is to plant them in soft, airy soil. Keep an eye on the weather forecast and protect vulnerable plants with row covers, cloche covers, or low and high tunnels.Everyone enjoys a sweet, crunchy carrot, but many gardeners find them a bit tricky to grow. Other crops, like pumpkins and winter squash, will experience foliage die-back after a light frost, but the fruits may not suffer damage.īy learning which vegetables have the best cold tolerance, gardeners can often protect their spring plants and extend the fall harvest season by several weeks. Gardeners find many of these crops turn sweeter after a light frost in the fall.Īdditionally, some root crops-like carrots and parsnips-can safely remain in the ground until it freezes. Dropping temperatures and shorter days also stimulate these plants to convert stored starches to sugars. Plants, like those listed below, have more space between their cells and are better adapted to withstand internal freezing.Īs a general rule of thumb, cold season crops like cruciferous veggies and root crops have the best cold tolerance. Most often, frozen plant tissues take on a water soaked appearance after a freeze event. When this happens, the tissues are permanently damaged by the expansion of water as it freezes. While meteorological freezes are measured by temperature, a biological freeze depends upon whether or not the water inside the plant’s cells and tissues turns to ice. The true heroes of cold tolerance are vegetables which can withstand freezing temperatures in the 26 to 28 degree F. Veggies which can tolerate frosts and light freezes include: Thus, how cold can broccoli tolerate depends upon weather patterns, not single weather events. They will be better able to withstand colder temperatures than those plants experiencing a sudden drop in temperature. Plants exposed to dropping temperatures over the course of several weeks will make biological adaptions. (-2 to 0 C.) range, providing they have been preconditioned to cold weather. Generally speaking, these frost-tender vegetables should be harvested, or the plants protected, whenever a frost warning is issued:įrost-tolerant veggies can survive several hours in the 28 to 32 degree F. (-1 C.) for five to ten minutes or when temps remain in the 31 to 32 degrees F. A killing frost can occur when temperatures drop below 30 degrees F. If you’ve ever wondered, “how cold can pepper plants tolerate,” the answer is not simple. This phenomenon also means low areas, like valleys, can experience frost when plants on higher ground are safe. Temperatures at garden level are often cooler than the point where official temperatures are measured. This confusion happens because official temperature readings are measured at 4 feet (1 m.) above the ground.Ĭold air is denser than warm air. Yet many gardeners experience frost when the official temperature readings are above 32 degrees F. In general, meteorologists issue a frost or freeze warning when ground temperatures are likely to drop to 32 degrees F. This is because cold tolerance is dependent on several factors such as length of the cold spell, preconditioning, and the type of vegetable. Even experienced gardeners don’t always get it right. If you’ve ever wondered how cold is too cold for vegetable garden produce, you’re not alone. Let’s look at how these terms are defined, and which veggie falls into each category. How cold can tomatoes tolerate? What about peppers, onions, and cabbage? Whether you’re planting in the spring or harvesting in the fall, knowing which veggies will survive frosts and freezes is essential for the success of your garden.
