How Low Of A Temperature Can Peas Stand?

Peas are a popular vegetable that can be enjoyed in many ways. They can be eaten raw as a snack, added to salads or soups, cooked as a side dish, and even used in main courses. However, one question that often arises among gardeners and farmers is, how low of a temperature can peas stand?

Understanding the Cold Tolerance of Peas

Peas are cool-season crops that thrive in temperatures ranging from 40°F to 70°F. They can tolerate light frosts when they are young but become less tolerant as they mature. The cold tolerance of peas depends on various factors such as the variety of pea, the stage of growth, duration of low temperatures, and other environmental factors.

Some varieties of peas are more cold-tolerant than others. For example, some varieties like Oregon Sugar Pod II have been bred specifically for their ability to withstand colder temperatures. In addition, peas that are exposed to cold temperatures for short periods are more likely to survive than those exposed to prolonged periods of cold.

What Happens When Peas are Exposed to Low Temperatures?

When peas are exposed to low temperatures, their cell walls may rupture, and ice crystals may form inside their cells. This can cause irreversible damage to the plant and result in stunted growth, yellowing of leaves, and poor yields.

If the temperature drops below 28°F (-2°C), there is a high risk of freezing injury to the plant. At this temperature, the water inside the plant's cells freezes, leading to the formation of ice crystals that can rupture cell walls and damage the plant's tissues.

Protecting Peas from Low Temperatures

To protect your peas from low temperatures, it is important to plant them at the right time. Peas should be planted in early spring, as soon as the soil can be worked. This will ensure that your plants have enough time to mature before the hot summer months arrive.

If you are planting peas in a colder climate, you can start them indoors and then transplant them outside once the weather warms up. This will give your plants a head start and increase their chances of survival.

In addition, you can protect your peas from frost by covering them with blankets or tarps during the coldest nights. Make sure to remove the covers during the day to allow for air circulation and prevent overheating.

The Bottom Line

In conclusion, the cold tolerance of peas depends on various factors such as the variety, the stage of growth, and the duration of low temperatures. Generally, peas can tolerate temperatures as low as 20°F (-7°C) for short periods. However, if the temperature drops below 28°F (-2°C), there is a high risk of freezing injury to the plant. To protect your peas from low temperatures, it is important to plant them at the right time and take measures to protect them from frost.
