When to Plant Beets in Maryland (2026 Guide)
Beets are a delicious and versatile vegetable that can thrive in Maryland's varied climates. From the sweet, earthy roots to the nutritious greens, both parts of the beet can elevate any meal. With Maryland's growing zones ranging from 5b to 6b, understanding when to plant beets is crucial for a bountiful harvest. As you prepare your garden, keep in mind that the frost dates in your area will greatly influence your planting schedule.
For instance, in Zone 6b, the median last spring frost is April 11, while the first fall frost typically occurs on October 29. This gives gardeners about 201 days in the frost-free growing season to cultivate beets successfully. On the other hand, those in Zone 6a should note that their last spring frost falls around April 18, with a shorter growing season of approximately 187 days.
If you reside in Zone 5b, your last spring frost occurs later on May 4, limiting your frost-free days to about 159. Given these frost dates, it's essential to plant beets correctly to maximize their growth potential. By following regional guidelines, you can enjoy a plentiful harvest while accommodating the unique climatic factors that affect beets in Maryland.

Common Mistakes Growing Beets in Maryland
- One common issue in Maryland gardens is overcrowding of beet plants. With beet 'seeds' being clusters, many inexperienced gardeners end up with more seedlings than they can manage. It's essential to thin seedlings to about 3–4 inches apart for optimal growth.
- Maryland's weather can be unpredictable with late spring frosts occurring even after the typical last frost dates. This can damage young beet plants. Always keep an eye on the weather forecast after planting to safeguard against unexpected cold snaps.
- Humidity in Maryland can lead to fungal issues like downy mildew, especially if rotating crops improperly. Avoid planting beets in a location previously occupied by spinach or chard to help mitigate this risk and ensure healthier beet plants.
- New gardeners in Maryland often wait too long to harvest beets, allowing them to grow oversized and woody. Ideally, beets should be harvested when they reach 1.5 to 2.5 inches in diameter for the best flavor.
- Overwatering is another frequent mistake gardeners make in Maryland due to the misconception that beets need constant water. While consistent moisture is vital, beets can suffer from rot if the soil remains overly saturated.
Frequently Asked Questions
What if I'm in a cold pocket of Maryland?
If you find yourself in a colder area of Maryland, consider starting beets later in the season. You may need to adjust your planting schedule to match local weather patterns and give your crops more time to mature.
Can I still plant beets in May?

What pests should I watch for when growing beets?
