Peas: How Cold Is Too Cold?
Peas are one of the first crops that you can plant in your garden. Many people say that peas should be planted before St. Patrick’s Day or the Ides of March. However, in many areas, these dates fall early in the season when there can still be frost, freezing temperatures, and even snow. While peas can tolerate cold temperatures and even grow best in cool weather, there is a limit to how cold they can handle.
How Low of a Temperature Can Peas Tolerate?
Peas can survive in temperatures as low as 28 degrees Fahrenheit (-2 degrees Celsius). If temperatures don’t drop below this point, peas and pea seedlings will be fine.
When temperatures are between 20 and 28 degrees Fahrenheit (-2 to -6 degrees Celsius), peas can survive but may suffer some damage. This is especially true if there is no snow cover to insulate the plants.
If there is a blanket of snow covering the peas, they can tolerate temperatures as low as 10 degrees Fahrenheit (-12 degrees Celsius) or even 5 degrees Fahrenheit (-15 degrees Celsius) without too much damage.
Optimal Temperature Range for Pea Growth
Peas grow best in temperatures between 50 and 70 degrees Fahrenheit (10 to 21 degrees Celsius). However, peas can still grow and produce outside of this temperature range.
Planting Peas in Cold Climates
While folklore may say that you should plant your peas by the middle of March, it’s important to consider your local climate and weather patterns before doing so.
If you live in an area with cold winters, it’s best to wait until the soil has warmed up a bit before planting peas. You can also start peas indoors and transplant them outdoors when the weather is warmer.
Protecting Pea Seedlings from Cold Damage
If you plant peas in cold weather, there are a few things you can do to protect them from damage:
- Use a cold frame or cloche. This will provide insulation and protection from the wind.
- Cover the peas with mulch. Mulch will help to insulate the soil and keep the roots warm.
- Water the peas regularly. Watering will help to keep the soil moist and prevent the roots from drying out.
By following these tips, you can help your peas survive and thrive in cold weather.
Additional Tips for Planting Peas in Cold Climates
- Choose cold-hardy varieties of peas.
- Plant peas in a sunny location.
- Plant peas deeply, so the roots are well-protected.
- Water peas regularly, especially during dry spells.
- Fertilize peas according to the package directions.
- Keep an eye on peas for pests and diseases.
With a little care and attention, you can grow delicious peas in even the coldest climates.
