What Temperature Will Kill Vegetables? (A Checklist)

Under any circumstances that you might be growing your own fresh vegetables, you have to know the temperature range that they thrive in.


Some plants will not grow or thrive in the same ranges of temperatures.

Some will not grow at all.

By choosing the right vegetables and growing them in the proper environment at the right temperature, you will have an abundant harvest this season, no matter what time of year it is.

Some of the more hardy vegetables that can survive temperatures as low as 31 degrees F., are artichokes, asparagus, Brussels sprouts, carrots, cabbage, cauliflower, celery, cherries, endive, kale, kohlrabi, parsnips, strawberries, spinach, squash, and yams.

Other vegetables that cannot endure low temperatures as low as 26 degrees F., include beans, corn, eggplant, peas, prunes, spinach, and zucchini.

Hardy vegetables generally do well when planted in rows along the edge of your garden bed. Be careful not to plant too close to other plants in your garden bed.

All of these hardy vegetables are very healthy and very easy to grow in almost any location. They can tolerate frosts, just like most plants.

As long as they are not exposed to extremely cold temperatures, they will typically do well. Even if you live in a location that does occasionally experiences below-freezing temperatures, you can grow most vegetables just about anywhere, as long as you provide a nice sunny spot that receives at least six hours of bright sunshine every day.

Some plants will only do well in slightly cold temperatures. Lettuce, green beans, cauliflower, broccoli, cabbage, and Brussels sprouts are all cold tolerant. Be sure to check the package on these vegetables to find out their recommended temperatures.

It is generally safe to plant these vegetables in any location that is between sixty and ninety degrees Fahrenheit. However, if you live in a colder region, be sure to protect these delicate plants with thick gloves and a cold-weather hat.

Some plants will do better in the hot sun than in low light. Some will do better in partial shade than in full sunlight. Tomatoes, peppers, sweet potatoes, and squash plants do best in full sun.

In general, when it comes to vegetables, the lower the temperature, the longer they will stay alive. But remember, with any gardening activity, it is important to use common sense and exercise caution.

If you have not attempted to answer the question, “what temperature will kill vegetables?” yourself, talk to experienced gardeners who can give you the information you need.

What temperature can vegetable plants tolerate?

There are three main questions that vegetable gardeners need to answer when planning their vegetable gardens.

They are, What plant can I expect to grow in this area, Is it cold or warm where the plant is located and, How much sun or shade will the plants have. Answers to these questions will influence the choices you make regarding the plants you choose and the layout and design of your vegetable garden. The answers you receive will also affect the quality of the produce you receive from your gardening efforts.

The first question to address is what temperature can the plants be expected to grow in. There are many vegetables, plants that can be grown successfully in various temperatures, some more successfully than others. Keep in mind though, that if you are not choosing bulbs or vegetables for your kitchen, you may not want to invest a lot of time and money into planting for vegetables. Many people choose to plant vegetables to add color and produce to their gardens, or to develop a hobby with plants they enjoy.

However, if you are growing vegetables for a market such as grocery stores, restaurants or cafes, you will need to choose bulbs or vegetables that can be grown in a range of temperatures. If you buy seedlings from a nursery, you should consider what the plant may not be able to tolerate. There are some plants that can tolerate moderate temperatures, such as tomatoes, while other plants may only tolerate extreme temperatures, such as peppers or strawberries. Be sure to ask a professional or knowledgeable person in the store what they recommend as well as check the plant’s USDA Plant hardness report to determine the suitability of the area you are planning to grow in.

Another important consideration is how much sun or shade the plant can tolerate. There are plants that require a lot of sunlight or intense heat in order to grow well. Others may only need minimal amounts of either direction.

In either case, you must be aware of the type of climate you are living in. For example, areas that experience extremely cold temperatures during the winter months may only need to be occasionally watered while areas that experience milder winters can go without water for extended periods.

The location of where you want to grow your garden will play an important role in determining the temperature of the plants you select.

For example, if you are planning to grow your tomatoes in the garden, the temperature will probably have to be substantially colder than if you were planning to grow them in a shaded window.

Likewise, if you are planning to grow herbs, a sunny location would be preferable because they prefer a cooler temperature. In the summer, mint may do best in a south-facing location.

With the information provided here, you are now armed with a basic outline of what temperature can vegetable plants tolerate? A simple way to find out is to ask your local nursery manager or grower, as well as friends and neighbors if they have any suggestions for you. Good luck!

What vegetables can survive a freeze?

For many gardeners, the question of what vegetables can survive a frost has a different answer than the one they gave when asked what vegetables can’t survive a frost.

In reality, a frost will kill any vegetables that are in your garden unless you have bought plastic pots or shaded them completely to keep out the sunlight and cold.

But if you live in an area where this happens often you should know about some of the best ways to protect your plants so they don’t die from the cold.

If you are lucky enough to live in an area where the frost never goes fully through your soil then you have a long life span for your vegetables. If you are not so lucky, there is really no way for you to know what vegetables will be in your garden next spring because all of your hard work will have been for nothing.

The first thing you want to do when you discover that your vegetables are not growing is to check the soil to see if it needs to be changed. If you don’t do this the ice will build up on top of the soil and you will end up killing your plants before they have a chance to produce any vegetables. So make sure that the soil is thoroughly checked.

There are two primary reasons that vegetables will not grow during a frost. They will either be too small or too much cold. If your vegetables are too small they will not reach the light that they need to grow and they won’t get a chance to break down completely. Vegetables that are too cold are also very prone to drying out and falling over. If you allow your vegetables to freeze to a degree where they are still alive, you are taking a risk because they may never have had a chance to break down completely.

In order to know what vegetables can survive a winter frost the best way to do this is to make sure that you don’t plant anything that could be affected by freezing. This includes all green vegetables, lettuce, spinach, and beans, peas, cabbages, corn, squash, okra, and any fruits. Green vegetables like kale and cabbage are some of the best vegetables to grow during the winter months when they are likely to be cold.

You should leave the greens on the vine if possible as this will ensure that they don’t dry out. Cucumbers are another vegetable that can be planted at ground level and wrapped in plastic to protect them from wind and snow.

Once you know what vegetables can survive a freeze, you can start planting them. Make sure that you only plant things that can handle the cold. For example, onions and carrots won’t grow very well in the winter as they are too small.

Cabbage, potatoes, and squash can survive a frost but they will be much smaller than normal. Other vegetables may fare better during the winter months but you need to experiment with them to find out.

Final thoughts

One of the biggest problems is that they won’t do much good after the winter. Unless you store them carefully they will not last very long and will have lost most of their nutrients.

This means that it may be more expensive to buy high-quality produce once the season starts again in the spring.

However, if you are growing high-quality produce you should be able to survive the winter season with little expense and hassle.
