When to Plant Peas in Maryland (2026 Guide)
Growing peas can be an exciting endeavor for any gardener in Maryland, with the right timing being crucial for a successful harvest. Understanding the specific frost dates for the USDA hardiness zones within the state is essential in planning your planting schedule. For example, in Zone 6b, the median last spring frost is on April 11, making early April a perfect time for direct sowing peas in a suitable garden plot.
Peas thrive in cooler temperatures, ideally ranging between 50–70°F, which makes them one of the first crops you can sow in the spring. However, they do require soil temperatures to be warm enough for germination, ideally between 40°F and 50°F. This makes sowing peas early in the season a balancing act, especially in regions like Maryland where the weather can vary dramatically.
In Maryland, knowing whether you are in Zone 6a, 6b, or 5b directly influences when you should plan your gardening. Each zone presents unique frost dates: the last spring frost in Zone 6a occurs around April 18, while those in Zone 5b have to wait until May 4. By planning your garden using this information, you'll ensure that your pea plants grow strong and yield a delicious harvest.

Common Mistakes Growing Peas in Maryland
- One common mistake Maryland gardeners make is planting peas too late in the spring. Waiting too long can lead to poor yields because higher summer temperatures negatively impact pea growth.
- Another frequent error is misunderstanding the soil temperature requirements for pea germination. Maryland's climate can lead to cold, damp soils in early spring, so ensure that the soil reaches the optimal 40°F to 50°F range before sowing.
- Many gardeners in Maryland overlook the significance of direct sowing peas rather than trying to start them indoors. Given their delicacy and sensitivity, peas resent being transplanted, leading to stunted growth or poor yields.
- Companion planting is also frequently mismanaged. Planting nitrogen-heavy crops next to peas is a great idea, but failure to follow this rotation can diminish the benefits of the pea roots in future crops.
- Lastly, Maryland's humid summers can lead to diseases affecting peas if they are not harvested on time. Failing to check pods daily can result in tough, inedible peas, especially for the snap and snow varieties.
Frequently Asked Questions
Can I plant peas if I live in a colder area of Maryland?
Yes, you can still plant peas in colder areas, such as Zone 5b, but be mindful of the later planting dates. Wait until your soil temperature warms to around 40°F before direct sowing to ensure successful germination.
What should I do if the last frost occurs later than expected?
If a late frost threatens your plants after sowing, consider covering them with lightweight fabric or row covers. This provides protection and can help maintain warmer soil temperatures during unexpected cold snaps.
Is it too late to plant peas in May?
While late spring planting is possible, it's best to avoid sowing peas after May 4 in Zone 5b. Planting later can lead to poor yields and declines in pea quality due to rising temperatures.
How often should I check my peas for harvest readiness?
Check your pea plants every 2-3 days during the peak harvest period. Regularly harvesting snap and snow peas ensures peak flavor and tenderness before the pods become tough or overly mature.
What should I do with spent pea plants after harvest?
Do not pull spent pea plants entirely out of the ground. Cut them at the soil line and leave the roots to decompose, enriching the soil with nitrogen for the next planting season.
