When to Plant Peas in Vermont (2026 Guide)

Growing peas in Vermont can be a rewarding experience, especially given their suitability for the cooler climate and nutrient-rich soil. Peas are among the first vegetables to be planted in the garden as they thrive in cooler temperatures, ideally growing between 50 and 70°F. With the median last spring frost date of May 8 in Zone 5b, gardeners can take advantage of the early growing season and enjoy fresh peas by early summer.

To plant peas effectively, it's important to sow them directly in the soil once it is workable, usually in late winter or early spring. Given their short growing window and dislike for transplanting, peas should not be started indoors. As much of Vermont has a frost-free growing season of about 148 days and an early fall frost setting in around October 3, careful timing ensures a bountiful harvest.

There are three main types of peas to consider: shelling peas, snap peas, and snow peas, each thriving under similar conditions. It is crucial to install a trellis before planting to ensure proper support, especially for climbing varieties. Because pea plants fix nitrogen in the soil, they set the stage for a healthy garden by enriching the soil for subsequent crops.

Common Mistakes Growing Peas in Vermont

One common mistake among Vermont gardeners is planting peas too late in the season. Given the average last frost date of May 8, it's important to begin sowing as soon as the soil is workable, ideally by mid-March to ensure optimal growth.
Many gardeners in Vermont underestimate the rapid decline in pea growth once summer heat sets in. Temperatures consistently above 80°F can lead to poor pod development, so aim for careful timing in planting to ensure a successful harvest.
Vermont's spring weather can be unpredictable, and late-season snow can catch gardeners off guard. Protect emerging pea plants by using row covers to guard against unexpected frost events during this critical early growth period.
Another frequent error is neglecting trellising. Even bush varieties can benefit from support to keep pods off the ground, helping avoid rot and improving overall yield. Install trellises as you plant for the best results.
In Vermont, gardeners often prematurely harvest peas, thinking they're ready too soon. Waiting until pods are plump and rounded—especially for shelling peas—is critical, as early harvesting can diminish flavor and yield.

Frequently Asked Questions

What if I'm in a cold pocket of Vermont?

If you're in a colder part of Vermont, sow your peas a bit later, perhaps closer to the end of April. Monitor soil temperature, and wait until it's consistently above 40°F for good germination.

Can I still plant peas in May?

While it is best to plant peas by mid-April, you can still plant them in early May as long as you ensure the soil is workable and temperatures remain cool. Be aware that an earlier harvest may be affected.

How often should I water my pea plants?

Peas prefer consistently moist soil, especially during germination and pod development. Water them once a week, and more frequently in dry spells, but avoid waterlogging the roots.

What pests should I watch for when growing peas?

Peas may attract aphids, thrips, and root maggots. Regularly inspect your plants for signs of pests and use organic treatments if necessary. Keeping your garden clean helps minimize pest issues.

Can I save seeds from my pea plants for next year?

Yes, saving seeds from mature peas is a viable option! Make sure to select the healthiest pods, let them dry completely, and store them in a cool, dark place for future planting.
