Vaccinium ashei 'Reade' - Vernon Blueberry

The Vernon blueberry is a hardy and adaptable southern variety, known for its firm berries with good to excellent flavor and large size. Its blooming time avoids late frosts, making it a reliable choice for many climates. Although self-fertile, it can benefit from cross-pollination with another variety. Vernon is a vigorous plant with high, consistent yields. It was introduced by the University of Georgia and is suitable for Zones 6-8, with a recommended spacing of 5 feet.

Blueberry Care Guide

Blueberries are a popular and nutritious fruit that thrives in specific conditions. Whether you’re growing blueberries in the ground or containers, understanding the proper care techniques is essential for a bountiful harvest. Below is a comprehensive guide to planting, caring for, and troubleshooting common blueberry issues.

Overview of Blueberry Care

• Sun Requirements: Full sun (at least 6 hours per day) is crucial for high yields and healthy growth.

• Soil Requirements: Well-drained, acidic soil with a pH between 4.5 and 5.2 is optimal.

• Water Requirements: Blueberries need consistent moisture, especially during the growing season, but they do not like "wet feet" (waterlogged roots).

• Mulch: Mulching helps conserve moisture, suppress weeds, and add organic matter to the soil.

Planting Blueberries

1. Site Selection:

• Choose a sunny spot that gets 6+ hours of sunlight daily. Blueberries can tolerate partial shade but will produce fewer fruits.

• Prepare the soil by ensuring it is well-drained, rich in organic matter, and acidic. Ideal pH should be between 4.5 and 5.2.

2. Soil Preparation:

• Dig a 5-foot wide, 10-inch deep bed for each plant. Mix in 80% moist peat to improve the soil’s acidity and organic content.

• Shredded pine bark mulch and leaf mold compost are a great alternative to peat and will create the ‘forest floor’ environment ideal for vacciniums.

3. Planting:

• Spacing: Space plants about 5 feet apart to allow room for growth and proper airflow.

• When planting, remove the blueberry plant from its pot, spread the roots, and position the roots in the newly prepared soil. Gently integrate the roots into the surrounding soil, then water well.

4. Mulching:

• Mulch around the base of the plant with aged bark mulch, pine bark, pine chips, or pine sawdust. A 2–4-inch layer will help retain moisture, suppress weeds, and improve soil health over time.

Container Grown Blueberries

Blueberries can also be successfully grown in containers, which is ideal for smaller spaces or regions with poor soil.

1. Soil for Containers:

• Use a well-draining mix of peat moss and aged bark chips. Blueberries like acidic, loose soil.

• Avoid using heavy soils like garden soil or clay-based mixes.

2. Fertilization:

• Apply a slow-release fertilizer such as Holly-tone or cottonseed meal during the growing season to promote healthy growth.

• You can also use liquid fertilizers or time-release products throughout the season.

3. Winter Care:

• In winter, if temperatures drop below 20°F (-6°C), protect container plants by mulching heavily or insulating the pot to prevent the roots from drying out.

4. Planting Times:

• Container-grown blueberries can be planted year-round, but ensure they are kept moist during winter to prevent root damage from drying out.

5. Common Container Sizes:

• 1-Quart: 1 year old, may produce some fruit the first year.

• 1-Gallon: 1–2 years old, often produces fruit in the first season.

• 3-Gallon and larger: 2–3 years old, usually fruit-bearing in the first year.

Watering Blueberries

1. Watering Needs:

• Blueberries are highly sensitive to water stress. Water thoroughly from planting time until the plant goes dormant.

• During dry periods, new plantings may require daily watering to prevent drying out.

• If unsure whether the soil is dry, dig a few inches into the bed and check moisture levels.

2. Avoid Overwatering:

• Make sure the soil is well-draining. Waterlogged soil can cause root rot. If the soil stays too wet, consider adjusting the drainage or location.

Pruning Blueberries

1. Pruning Young Plants:

• In the early years, prune to remove dead, diseased, or damaged canes and any weak, twiggy growth. This encourages strong, healthy growth.

2. Pruning Mature Plants:

• As your plants mature, focus on maintaining 8–10 canes. Remove the oldest dark canes (typically around 5 years old), as well as any dead, diseased, or low-growing branches.

• Open the center of the plant to allow better airflow and sunlight penetration, which reduces disease risk.

3. Fruit Overload Pruning:

• If your plant is overbearing with small fruit, pruning some young twigs under 2 inches can help balance the load and promote healthier fruit.

Mulching

1. Benefits of Mulching:

• Moisture Retention: Mulch keeps the soil around the roots consistently moist.

• Weed Control: Mulch helps suppress weed growth, which competes with blueberries for nutrients.

• Soil Improvement: Organic mulches decompose over time, enriching the soil with valuable nutrients.

2. Recommended Mulches:

• Pine Bark, Pine Chips, Pine Needles, or Pine Sawdust are ideal for blueberries due to their acidity and the gradual addition of organic matter.

Common Issues & Troubleshooting

1. Brown Leaves, Some Green at the Base:

• This often indicates poor root-to-soil contact or a dry root ball. Press your finger into the root ball; if it’s dry, dig up the plant, soak it in water overnight, then replant, ensuring the roots are well-watered.

2. Whole Plant Dies, Bark Shriveled:

• Likely due to white grubs eating the bark and roots. Check the mulch line and dig around the base to inspect for grubs. Grub damage can be especially common in old sod or under heavy mulch. Remove affected plants, and consider using grub control if necessary.

3. Red Leaves, No Growth:

• Could indicate planting too deep. Dig up the plant and replant at the correct depth.

• Ensure adequate organic matter in the soil. If necessary, mix in sphagnum peat moss.

• Test soil pH—low iron levels or poor drainage could also cause red leaves and poor growth.

4. Older Plants Look Good, But Not Growing:

• Possible causes include pests like scale (check for insects on the bark), grubs, or voles. Look for signs of damage and apply appropriate treatments.

• Another potential issue could be root rot from poorly draining soil. If the soil is too wet, consider improving drainage or moving the plant to a new location.

Fertilizing Blueberries

1. Fertilization Needs:

• Blueberries require light, frequent feeding with organic fertilizers like Holly-tone, cottonseed meal, or fish emulsion.

• Avoid using too much nitrogen, as it can encourage excessive leaf growth at the expense of fruit production.

2. Timing:

• Apply fertilizers in early spring before new growth begins and again in late spring or early summer to support fruit development.

Ripening Order of Blueberry Varieties

For those growing different varieties of blueberries, here's a typical ripening order for fresh blueberries:

1. Early Season: Reka, Legacy, O'Neal, Star, Sharpblue

2. Mid-Season: Sunshine Blue, Northland, Climax, Premier, Columbus, Yadkin

3. Late Season: Tifblue, Trentberry, Powderblue

 Conclusion

Blueberries are a rewarding plant to grow when given the right care. Whether you’re growing them in the ground or containers, these plants thrive in acidic, well-drained soil, with ample sunlight and consistent moisture. Pruning, mulching, and proper watering are crucial to ensuring healthy growth and a bountiful harvest. With the tips provided in this guide, you’ll be well on your way to enjoying fresh blueberries from your garden!
