Pennsylvania’s diverse climate zones support both northern and southern highbush blueberry varieties with proper site selection. Finding the best blueberries to grow in pennsylvania means matching the right cultivar to your specific region, soil, and sunlight conditions. This guide walks you through the top picks, planting steps, and care tips to get a bountiful harvest.
Blueberries thrive in acidic soil with a pH between 4.5 and 5.5. Pennsylvania’s native soils often lean toward neutral or alkaline, so you might need to amend the ground. Raised beds or containers work well if your native soil is too heavy or alkaline.
Most of the state falls into USDA hardiness zones 5 through 7. Northern highbush varieties handle colder winters in zones 5 and 6. Southern highbush types do better in warmer zones 6 and 7, especially in southeastern Pennsylvania.
Best Blueberries To Grow In Pennsylvania
Here are the top-rated blueberry cultivars for Pennsylvania gardens. Each one has been tested for local climate, disease resistance, and fruit quality.
Northern Highbush Varieties
These are the most reliable for most of Pennsylvania. They need around 800 to 1,000 chill hours (hours below 45°F) to set fruit properly.
- Bluecrop – A classic mid-season variety. It produces large, firm berries with a sweet-tart flavor. Bluecrop is disease-resistant and handles a range of soil conditions. It grows 5 to 6 feet tall.
- Blueray – Known for its intense blue color and rich taste. Blueray ripens early to mid-season. It is cold-hardy down to zone 4 and works well in northern PA.
- Jersey – A late-season variety that extends your harvest into August. Jersey berries are smaller but very sweet. It is a vigorous grower and tolerates wetter soil better than most.
- Patriot – Early ripening with large, light blue berries. Patriot is extremely cold-hardy and adapts to heavier clay soils. It stays compact at 4 to 5 feet.
- Northland – A half-high hybrid that stays under 4 feet. Northland is perfect for small spaces or containers. It produces medium-sized, flavorful berries and is very winter hardy.
Southern Highbush Varieties
These require fewer chill hours (150 to 600) and thrive in warmer parts of Pennsylvania. They often ripen earlier than northern types.
- Misty – Needs only 300 chill hours. Misty produces large, sweet berries with a hint of floral flavor. It grows well in southeastern PA and is heat-tolerant.
- O’Neal – A popular early-season variety. O’Neal has excellent flavor and large fruit. It requires 400 to 500 chill hours and does best in zone 6 or warmer.
- Sunshine Blue – A dwarf variety that reaches only 3 feet. It needs 150 to 300 chill hours and is self-fertile. Sunshine Blue is ideal for patio containers in warmer areas.
- Jewel – Ripens mid-season with very large, firm berries. Jewel needs 400 to 500 chill hours and has good disease resistance. It is a top choice for home gardens in southern PA.
Rabbiteye Varieties
Rabbiteye blueberries are less common in Pennsylvania but can succeed in the warmest microclimates. They need a second variety for cross-pollination.
- Tifblue – A vigorous rabbiteye that produces firm, sweet berries. It needs 500 to 600 chill hours. Tifblue works best in zone 7 areas like Philadelphia’s suburbs.
- Powderblue – Late-season rabbiteye with a powdery bloom on the skin. Powderblue is drought-tolerant once established. It pairs well with Tifblue for pollination.
Site Selection And Soil Preparation
Blueberries need full sun for at least 6 to 8 hours daily. Partial shade reduces yield and fruit quality. Choose a spot with good air circulation to prevent fungal diseases.
Test your soil pH before planting. Penn State Extension offers affordable soil testing. If your pH is above 5.5, lower it by mixing in elemental sulfur or peat moss. Aim for a pH of 4.5 to 5.0 for best results.
Improving Drainage
Blueberries hate wet feet. If your soil is heavy clay, build raised beds 8 to 12 inches high. Mix in compost, pine bark, or sand to improve drainage. Containers at least 18 inches wide work well too.
Spacing And Planting
- Space highbush varieties 4 to 5 feet apart in rows 8 to 10 feet apart.
- Dig a hole twice as wide as the root ball but no deeper.
- Place the plant so the root crown is level with the soil surface.
- Backfill with a mix of native soil and acidic organic matter like peat moss.
- Water thoroughly after planting.
Planting Time And Pollination
Plant blueberries in early spring after the last frost. Fall planting is possible in zones 6 and 7, but spring gives roots more time to establish. Bare-root plants should be soaked in water for an hour before planting.
Most blueberries are self-fertile, but planting two or more varieties increases yield and berry size. For northern highbush, pair Bluecrop with Blueray. For southern types, Misty with O’Neal works well.
Watering And Mulching
Blueberries have shallow roots that dry out quickly. Keep the soil consistently moist, especially during fruit development. Drip irrigation is ideal. Aim for 1 to 2 inches of water per week.
Mulch with 3 to 4 inches of pine bark, pine needles, or wood chips. This conserves moisture, suppresses weeds, and gradually acidifies the soil. Replenish mulch each spring.
Fertilizing Blueberries
Use a fertilizer formulated for acid-loving plants. Look for a product with an N-P-K ratio like 10-10-10 or 12-4-8. Apply in early spring before new growth starts, then again after harvest.
Avoid fertilizers with too much nitrogen, which can burn roots. Organic options include cottonseed meal, fish emulsion, or blood meal. Always water after applying fertilizer.
Pruning For Productivity
Prune blueberries in late winter or early spring while they are dormant. Remove dead, diseased, or crossing branches. Thin out old canes (older than 6 years) to encourage new growth.
For young plants, remove all flowers in the first year to direct energy into root development. In year two, allow a small crop. By year three, you can let them fruit fully.
Annual Pruning Steps
- Cut back any broken or damaged branches.
- Remove low-growing branches that touch the ground.
- Thin the center of the bush to allow light and air in.
- Leave 4 to 6 strong canes per mature bush.
Common Pests And Diseases
Blueberries in Pennsylvania face a few challenges. Birds love the ripe fruit. Cover bushes with bird netting as berries start to color. Deer may browse young plants, so use fencing or repellent.
Fungal diseases like mummy berry and powdery mildew appear in wet springs. Prune for airflow and avoid overhead watering. If needed, apply a copper-based fungicide early in the season.
Spotted wing drosophila is a small fruit fly that attacks ripening berries. Monitor with traps and harvest promptly. Remove any fallen fruit to break the pest cycle.
Harvesting And Storage
Blueberries ripen over several weeks. Pick them when they are fully blue and easily come off the stem. Taste a few to check sweetness. Harvest in the morning when berries are cool.
Store unwashed berries in the refrigerator in a shallow container. They keep for 1 to 2 weeks. For longer storage, freeze them on a baking sheet, then transfer to bags.
Winter Protection
Northern highbush varieties are cold-hardy, but a harsh winter can damage flower buds. Apply a thick layer of mulch around the base after the ground freezes. In zones 5 and colder, consider wrapping bushes in burlap if snow cover is thin.
Southern highbush types need extra care in colder parts of Pennsylvania. Plant them in a sheltered spot near a south-facing wall. Cover with frost cloth if a late spring freeze threatens.
Container Growing
If your soil is poor or you lack space, grow blueberries in containers. Use a pot at least 18 inches wide with drainage holes. Fill with an acidic potting mix designed for azaleas or blueberries.
Container plants need more frequent watering, sometimes daily in summer. Fertilize monthly during the growing season with a liquid acid fertilizer. Repot every 2 to 3 years to refresh the soil.
Extending The Harvest Season
Plant early, mid, and late-season varieties to enjoy fresh blueberries from June through August. For example, combine Patriot (early), Bluecrop (mid), and Jersey (late). This gives you a steady supply without a glut.
In warmer microclimates, add a southern highbush like Misty for even earlier fruit. Rabbiteye varieties extend the season into September in zone 7 areas.
Companion Plants
Blueberries grow well with other acid-loving plants. Plant them near rhododendrons, azaleas, or ferns. Avoid planting near vegetables that need neutral soil, like tomatoes or peppers.
Groundcovers like creeping thyme or low-growing sedum help keep soil cool and moist. But keep them away from the base of the blueberry bush to avoid competition.
Frequently Asked Questions
What Is The Best Blueberry Variety For Pennsylvania?
Bluecrop is the most reliable variety for most of Pennsylvania. It adapts to different soils, resists diseases, and produces high yields of tasty berries.
Can I Grow Blueberries In Partial Shade In Pennsylvania?
Blueberries need full sun for best fruit production. In partial shade, you will get fewer berries and they may be less sweet. Aim for at least 6 hours of direct sun.
How Do I Lower Soil PH For Blueberries In Pennsylvania?
Mix elemental sulfur into the soil several months before planting. Use 1 pound per 100 square feet to lower pH by one point. Peat moss also helps acidify the soil over time.
Do I Need Two Blueberry Bushes To Get Fruit?
Most varieties are self-fertile, but planting two different varieties increases cross-pollination. This leads to larger berries and higher yields. Even self-fertile types benefit from a partner.
When Is The Best Time To Plant Blueberries In Pennsylvania?
Early spring, after the last frost, is ideal. This gives the roots time to establish before summer heat. Fall planting is possible in warmer zones but carries more risk of winter damage.
Final Tips For Success
Start with a soil test to know exactly what your ground needs. Choose varieties that match your chill hours and hardiness zone. Water consistently, especially during dry spells.
Mulch every year to keep roots cool and acidic. Prune annually to keep bushes productive. Protect fruit from birds with netting. With these steps, you will enjoy homegrown blueberries for years.
Remember that patience pays off. Blueberries take 2 to 3 years to produce a full crop. But once established, a single bush can yield 5 to 10 pounds of fruit each season. That is a lot of pancakes and pies.
If you are in southeastern Pennsylvania, try southern highbush varieties like Misty or O’Neal. In the northern tier, stick with cold-hardy northern highbush like Patriot or Northland. Rabbiteye types are worth experimenting with in the warmest spots.
