Maine’s rocky soil and cool summers are surprisingly well-suited for a few remarkably lucrative crops. If you’re looking for the best cash crops to grow in maine, you need to focus on plants that thrive in short growing seasons and acidic soil. This guide breaks down the top options that actually turn a profit for small and mid-sized farms.
Forget trying to grow corn or soybeans at scale—Maine’s climate favors high-value specialty crops. Think berries, root vegetables, and niche greens. These crops fetch premium prices at farmers markets and through CSA programs. Let’s get straight to what works.
Best Cash Crops To Grow In Maine
Wild Blueberries: Maine’s Signature Crop
Maine is the largest producer of wild blueberries in the United States. These low-bush berries grow naturally in acidic, sandy soil. They require minimal inputs once established. A well-managed blueberry barren can produce for decades.
You can sell fresh blueberries at roadside stands or wholesale to processors. Frozen berries are also in high demand. The average yield per acre is around 5,000 to 10,000 pounds. Prices fluctuate, but organic wild blueberries often sell for $2 to $4 per pound.
Key Considerations For Blueberries
- Require 2-3 years to establish before first harvest
- Need biennial pruning (burning or mowing)
- Benefit from careful weed management
- Ideal for sandy, well-drained soil with pH 4.0-5.0
Potatoes: The Classic Maine Staple
Aroostook County is famous for potatoes. But you don’t need hundreds of acres to profit. Specialty potatoes like fingerlings, purple varieties, and Yukon Golds command higher prices. They store well, giving you a long selling window.
You can sell directly to restaurants or through farm stands. Seed potatoes are another profitable niche. Maine’s certified seed potato program is respected nationwide. Expect yields of 15,000 to 30,000 pounds per acre depending on variety and care.
Steps To Start Growing Potatoes
- Test your soil pH (aim for 5.5-6.5)
- Choose disease-resistant varieties like Kennebec or Caribou Russet
- Plant in well-drained soil after last frost (late May)
- Hill soil around plants as they grow to prevent greening
- Harvest after vines die back, usually September
Highbush Blueberries: Higher Yields, More Care
Unlike wild blueberries, highbush varieties grow on bushes up to 6 feet tall. They produce larger berries and higher yields per acre—up to 15,000 pounds. However, they require more irrigation, pruning, and pest management.
Highbush blueberries are excellent for pick-your-own operations. They also work well for fresh market sales. The initial investment is higher, but so is the potential return. Organic highbush blueberries can sell for $5 to $8 per pint.
Comparing Wild Vs. Highbush Blueberries
| Feature | Wild Blueberries | Highbush Blueberries |
|---|---|---|
| Yield per acre | 5,000-10,000 lbs | 10,000-15,000 lbs |
| Establishment time | 2-3 years | 3-4 years |
| Maintenance | Low | High |
| Price per pound | $2-$4 | $3-$8 |
Winter Squash: Long Storage, Steady Income
Winter squash like butternut, acorn, and delicata grow well in Maine’s climate. They store for months in a cool, dry place. This lets you sell them well into winter when fresh produce is scarce. Prices are highest from November through February.
You can grow squash on a small scale and still make money. A quarter-acre can produce 5,000 to 10,000 pounds. At $1 to $2 per pound, that’s a solid return. Squash also improves soil structure with its deep roots.
Best Winter Squash Varieties For Maine
- Butternut (Waltham or Burgess)
- Acorn (Table Queen or Autumn Delight)
- Delicata (Cornell’s Bush Delicata)
- Spaghetti squash
- Pumpkins for pie or decoration
Greens And Salad Mix: Quick Cash From Small Spaces
Lettuce, spinach, arugula, and kale grow fast in Maine’s cool spring and fall. You can get multiple harvests per season. Salad mix sells for $8 to $12 per pound at farmers markets. It’s one of the highest-value crops per square foot.
Use row covers to extend your season. Start seeds indoors in early April, then transplant after frost. Succession plant every two weeks for continuous harvest. A 100-foot bed can yield 50 to 100 pounds of salad mix per season.
Tools You’ll Need For Greens
- Floating row covers for frost protection
- Drip irrigation for consistent moisture
- Sharp harvest knife or scissors
- Wash station with cool water
- Salad spinner or dryer for post-harvest
Garlic: Low Effort, High Return
Garlic is almost perfect for Maine. Plant in October, harvest in July. It requires little attention during winter. Hardneck varieties like Music and German Extra Hardy thrive here. You can sell bulbs, scapes, and seed garlic.
Garlic stores for months at room temperature. A pound of seed garlic can yield 5 to 10 pounds of bulbs. At $10 to $15 per pound for culinary garlic, the math works. Garlic scapes sell for $3 to $5 per bunch in early summer.
Garlic Growing Timeline
- September-October: Plant cloves 4-6 inches apart
- November: Mulch heavily with straw for winter
- April: Remove mulch when shoots appear
- June: Harvest scapes (curly flower stalks)
- July: Harvest bulbs when lower leaves brown
Apples: Orchard Investment With Long-Term Payoff
Maine has a strong apple tradition. Heirloom varieties like Northern Spy and Macoun are popular. You can sell fresh apples, cider, or value-added products like pies and sauce. A mature apple tree yields 5 to 10 bushels per year.
Dwarf trees bear fruit in 3-4 years. Standard trees take 6-8 years. Consider a pick-your-own model to reduce labor. Hard cider is a growing market in Maine, and apples for cider sell well to local producers.
Apple Varieties That Perform Well In Maine
- McIntosh (classic, early ripening)
- Honeycrisp (high demand, needs care)
- Cortland (good for pies and salads)
- Empire (sweet, stores well)
- Liberty (disease-resistant)
Herbs: Niche But Profitable
Culinary herbs like basil, thyme, rosemary, and mint grow well in Maine’s summers. They have high value per pound. Fresh basil sells for $10 to $20 per pound. Dried herbs can be sold year-round. You can also grow medicinal herbs like echinacea and chamomile.
Herbs are ideal for small plots. A 100-square-foot bed can produce $500 to $1,000 worth of herbs per season. Consider selling potted herbs for home gardeners—they’re easy to ship and have low overhead.
Top Herbs For Maine Cash Crops
- Basil (sweet, Genovese, Thai)
- Mint (peppermint, spearmint)
- Thyme (English or lemon)
- Rosemary (needs winter protection)
- Chives (perennial, low maintenance)
Hops: A Growing Niche For Beer Lovers
Maine’s craft beer scene is booming. Local hops are in demand. Hops require trellising and careful pest management, but they can fetch $10 to $20 per pound dried. You’ll need at least 1 acre for a viable operation.
Hops are perennials that produce for 10-15 years. They need full sun and well-drained soil. Harvesting is labor-intensive, but the market is strong. Consider selling fresh (wet) hops for a premium during harvest season.
Hops Growing Challenges
- Require tall trellis system (15-20 feet)
- Susceptible to downy mildew and aphids
- Need irrigation during dry spells
- Harvest window is only 1-2 weeks
Strawberries: Early Season Cash
Strawberries are one of the first fruits to ripen in Maine. June-bearing varieties produce a heavy crop for 3-4 weeks. Day-neutral types bear all summer. You can sell fresh, frozen, or as jam. Pick-your-own is popular and reduces labor.
A well-maintained strawberry patch yields 5,000 to 10,000 pounds per acre. Prices range from $2 to $5 per pound. Plants need renovation after harvest and should be replaced every 3-4 years to maintain vigor.
Strawberry Varieties For Maine
- Earliglow (early, sweet)
- Honeoye (heavy yields)
- Jewel (large berries, good flavor)
- Seascape (day-neutral, continuous)
- Albion (day-neutral, disease-resistant)
Maple Syrup: Forest-Based Income
If you have maple trees, you have a cash crop. Tapping sugar maples produces syrup that sells for $40 to $80 per gallon. It’s a spring activity that doesn’t interfere with summer crops. You can also sell value-added products like maple candy and cream.
A single tap yields about 10 gallons of sap, which boils down to 1 quart of syrup. You need about 10-20 taps for a small operation. The equipment investment is moderate, but the profit margin is excellent.
Maple Syrup Production Steps
- Identify sugar maples (at least 12 inches diameter)
- Drill tap hole in late February
- Insert spile and hang bucket or tubing
- Collect sap daily during flow
- Boil sap to 66-67% sugar content
- Filter and bottle hot syrup
Cut Flowers: Beauty That Pays
Fresh-cut flowers are a high-value crop. Sunflowers, zinnias, dahlias, and snapdragons grow well in Maine. You can sell bouquets at farmers markets or to florists. A 1/4-acre flower patch can generate $10,000 to $20,000 per season.
Flowers have low startup costs and quick returns. Many varieties bloom within 60-90 days. You can extend the season with high tunnels. Dried flowers are also popular for wreaths and arrangements.
Best Cut Flowers For Maine
- Sunflowers (ProCut or Sunrich varieties)
- Zinnias (Benary’s Giant or Queen Lime)
- Dahlias (dinner plate or ball types)
- Snapdragons (Rocket or Potomac series)
- Cosmos (Sensation or Double Click)
Value-Added Products Boost Income
Processing your crops into jams, pickles, sauces, or dried goods increases profit margins. A $3 pound of berries becomes a $7 jar of jam. Value-added products also extend your selling season beyond harvest. Just check Maine’s cottage food laws for home processing rules.
You can also sell seeds, starter plants, or CSA shares. Diversifying your income streams reduces risk. Many Maine farmers combine several of these crops to create a resilient farm business.
