A Healthy Choice

Why grow blueberries? Ease of growing aside, these purple-blue berries excel in health benefits – whether consumed fresh, dried or frozen. Blueberries:

  • Are antioxidant-rich and packed with immune-boosting vitamin C
  • May help lower blood pressure
  • Fight cancer
  • Offer high fiber content
  • Contribute to improved brain health
  • Boast a low-glycemic index, which makes them an excellent carbohydrate choice for diabetics

What To Know Before You Grow

Blueberries need highly acidic soil to grow and produce. Soil pH should range from 4.0-5.5; the ideal pH is 4.5-4.8.

While some soils possess this low pH, typically you'll need to amend soil to shift the pH. Do this by adding peat moss, cottonseed meal, iron sulfate or slow-acting soil sulfur to planting areas. Using acid compost or mulch, such as oak leaf compost, pine needles or pine bark, can help maintain soil acidity.

Blueberries have shallow root systems, which makes them an ideal choice for raised beds or containers, especially in areas with naturally alkaline soil.

Other Keys To Success

Once you address soil pH, it's not difficult to keep Blueberry bushes healthy and productive. Plants need a well-drained site in full sun. Ensure a healthy crop by mulching, providing consistent moisture and removing weeds at the base of the plant. Use netting to protect ripening berries from birds. Learn about annual pruning from your local Cooperative Extension System office.

Types Of Blueberry Bushes

Northern Highbush: Naturally occurring in USDA Zones 4-7. Many hybrids available. Plants typically maintained 4-7 feet tall.

Southern Highbush: Hybrid of Northern Highbush and native Southern Blueberry species. Hardiness varies by cultivar; typically hardy in USDA Zones 6-10.

Lowbush: Naturally occurring in USDA Zones 3-6. This is the wild Blueberry found in Maine. Plants grow 1-2 feet high.

Rabbiteye: Best adapted to Southern climates. Plants grow 10-15 feet tall.

Half-High: Crosses of Northern Highbush and Lowbush types from the wild. Hardy in USDA Zones 3-5. Plants grow 3-4 feet tall. Reportedly the best wild Blueberry flavor – less sweet.

Different blueberry types ripen at different times during the growing season. Flowering times for the different types occur within roughly one week of one another, but fruits ripen from early to late summer. If you garden in regions with hard frosts, choose blueberries that:

  • Flower after your last spring frost
  • Ripen before your first fall frost

Pollination: From Flower To Fruit

Blueberries are technically self-pollinating, but you'll get more consistent and better yields when you plant more than one type for cross-pollination. Choose types with overlapping flowering times. Check with your local Cooperative Extension System office for best locally-adapted recommendations.
