Maryland’s transitional climate between humid subtropical and continental suits pepper varieties with broad temperature tolerance. When you’re searching for the Best Peppers To Grow In Maryland, you need options that handle humid summers and cooler nights. This guide walks you through top picks, planting tips, and common pitfalls so you get a bumper crop.
Maryland gardeners face a unique challenge. Summers can be hot and sticky, but spring and fall bring sudden chills. Peppers love warmth, but not extreme heat or cold. The key is choosing varieties that mature before frost and resist disease in humid conditions.
Let’s break down what works best for your Maryland garden, from the Eastern Shore to the mountains.
Understanding Maryland’s Growing Zones
Maryland spans USDA hardiness zones 5b through 7b. Western Maryland runs cooler, while the Eastern Shore and southern parts stay warmer longer. Your last frost date typically falls between April 15 and May 15. First frost hits around October 15 to November 1.
This means you have about 150 to 180 frost-free days. Most peppers need 60 to 90 days to mature. So timing matters. Start seeds indoors 8 to 10 weeks before your last frost date.
Soil temperature is critical. Peppers won’t grow well if soil is below 60°F. Wait until nighttime temps stay above 55°F before transplanting. Using black plastic or row covers can warm the soil faster.
Best Peppers To Grow In Maryland
Here are the top pepper varieties that thrive in Maryland’s climate. Each one handles humidity, temperature swings, and common pests.

Planting And Care Tips
Follow these steps for a successful pepper harvest in Maryland.
Start Seeds Indoors
Begin seeds 8 to 10 weeks before last frost. Use seed-starting mix. Keep soil warm at 70-80°F. Provide 14-16 hours of light daily.
Transplant seedlings after they have 2-3 sets of true leaves. Harden them off gradually over a week.
Prepare The Soil
Peppers need well-drained soil rich in organic matter. Test your soil pH. Aim for 6.0 to 6.8. Add compost or aged manure before planting.
Work in a balanced fertilizer like 10-10-10. Avoid high nitrogen, which promotes leaves over fruit.
Transplant Outdoors
Wait until soil temperature reaches 60°F. Nighttime temps should stay above 55°F. Space plants 18 to 24 inches apart in rows 2 to 3 feet apart.
Plant peppers deeper than they were in pots. Remove lower leaves and bury the stem up to the first set of leaves. This encourages stronger roots.
Water Consistently
Peppers need about 1 to 2 inches of water per week. Water deeply at the base. Avoid wetting leaves to prevent disease.
Use drip irrigation or soaker hoses. Mulch with straw or grass clippings to retain moisture and regulate soil temperature.
Fertilize Regularly
Feed peppers every 2 to 3 weeks with a balanced fertilizer. Switch to a low-nitrogen formula once flowers appear. Too much nitrogen causes lush leaves but few fruits.
Use compost tea or fish emulsion for organic options. Apply Epsom salt (1 tablespoon per gallon) when plants start flowering for better fruit set.
Support Your Plants
Tall varieties need staking or cages. Install supports at planting time to avoid root damage later. Use tomato cages, bamboo stakes, or trellises.
For heavy producers like bells, individual stakes work best. Tie stems loosely with soft twine.
Manage Pests And Diseases
Common pests in Maryland include aphids, flea beetles, and hornworms. Use insecticidal soap for aphids. Handpick hornworms. Row covers protect young plants from flea beetles.
Diseases like blossom end rot and powdery mildew can occur. Prevent blossom end rot by consistent watering and adding calcium. Improve air circulation to reduce mildew.
Rotate crops yearly. Don’t plant peppers where tomatoes, eggplants, or potatoes grew the previous year. This reduces soil-borne diseases.
Harvest At The Right Time
Most peppers are ready 60 to 90 days after transplanting. Harvest when they reach full size and color. Sweet peppers are sweeter when fully ripe (red, orange, yellow).
Use sharp scissors or pruners to cut peppers. Pulling can damage branches. Regular harvesting encourages more fruit production.
Extending The Season
Maryland’s fall can be unpredictable. Protect your peppers from early frosts.
- Use row covers or cloches when temps drop below 50°F.
- Plant in containers that can be moved indoors.
- Choose early-maturing varieties for a guaranteed harvest.
- Harvest all peppers before first frost. Green ones will ripen indoors.
You can also grow peppers in a greenhouse or high tunnel. This extends the season by several weeks.
Common Mistakes To Avoid
Even experienced gardeners make errors. Here are pitfalls to watch for.
- Planting too early. Cold soil stunts growth. Wait for warmth.
- Overwatering. Peppers dislike soggy roots. Let soil dry slightly.
- Underwatering. Stress causes blossom drop. Water consistently.
- Skipping fertilizer. Peppers are heavy feeders. Feed regularly.
- Ignoring pests. Check plants weekly. Act early.
- Harvesting too late. Overripe peppers attract pests. Pick promptly.
- Not hardening off. Sudden sun exposure burns leaves. Acclimate slowly.
Container Gardening Options
If you lack garden space, grow peppers in containers. Choose pots at least 5 gallons for most varieties. Smaller pots work for compact types.
- Use quality potting mix, not garden soil.
- Ensure drainage holes.
- Place in full sun (6-8 hours daily).
- Water more frequently than in-ground plants.
- Fertilize every 2 weeks with liquid fertilizer.
Good container varieties include ‘Ace’ bell, ‘Early Jalapeño’, and ‘Thai Hot’. These stay compact and produce well.
Preserving Your Harvest
You’ll likely have more peppers than you can eat fresh. Preserve them for year-round use.
- Freeze: Wash, chop, and freeze in bags. No blanching needed.
- Dry: Use a dehydrator or oven. Store in airtight jars.
- Pickle: Slice and pack in vinegar brine. Refrigerate or can.
- Ferment: Make hot sauce or pepper paste.
- Roast: Char skins, peel, and freeze.
Hot peppers dry especially well. String them up or use a dehydrator. Store in a cool, dark place.
