Blueberry Plant 'Top Hat'

Blueberries require a sunny spot with well-drained, acidic soil (pH between 4.5 and 5.5). They don’t tolerate waterlogged soil, so choose a location with good drainage.

• Sunlight: Full sun is ideal, but they can also tolerate partial shade.
• Soil: Blueberries thrive in acidic, peat-based soil. If your soil is alkaline, consider growing blueberries in large pots or raised beds with acidic compost.

Preparing the Soil

Blueberries need acidic soil, so it’s important to amend your soil before planting. If your garden soil is too alkaline (pH above 7), follow these steps:

• Add ericaceous compost or peat-based compost to lower the pH.
• You can also use sulfur to acidify the soil, but check pH levels regularly to ensure the right acidity.

Planting Blueberries

• Timing: Plant blueberries in early spring or autumn when the soil is moist and temperatures are cool.
• Spacing: Space plants about 45–60 cm (18–24 inches) apart to allow for growth.
• Planting Method: Dig a hole large enough to accommodate the root ball. Place the plant in the hole, making sure the top of the root ball is level with the soil surface. Fill the hole with acidic compost, then water thoroughly.

Watering

Blueberries have shallow roots and prefer consistent moisture, but they do not like being waterlogged. Water regularly, especially during dry periods, and use rainwater if possible, as tap water can be alkaline.

• Mulching around the base of the plant helps retain moisture and keeps the roots cool.
• Avoid using a sprinkler system, as it can overwater; instead, water at the base of the plant.

Feeding and Fertilising

Blueberries are sensitive to fertilisers, so use a specialist ericaceous (acid-loving) fertiliser in early spring. Be cautious not to over-fertilise, as this can lead to poor fruiting.

• Fertilising schedule: Apply fertiliser in early spring when the plant starts to show signs of new growth. Avoid fertilising late in the season as this can interfere with dormancy.
• Organic compost or well-rotted manure can also be used around the base of the plant to improve soil structure.

Pruning Blueberries

Pruning helps blueberries grow strong and productive. The best time to prune is in late winter or early spring before new growth begins.

• Young plants: In the first two years, remove any flowers to encourage strong root development.
• Mature plants: Cut back old or damaged wood to allow new, productive canes to grow. Aim to keep the centre of the plant open to allow sunlight to reach all branches.

Protecting Against Pests and Diseases

Blueberries are generally pest-resistant but can be susceptible to fungal diseases like powdery mildew or root rot in overly wet conditions. Common pests include aphids and birds.

• Bird protection: Use netting or other barriers to protect your crop, as birds love to eat ripe berries.
• Disease prevention: Ensure good air circulation around the plants and avoid overhead watering to reduce the risk of fungal diseases.

Harvesting Blueberries

Blueberries typically start producing fruit in the second or third year after planting. They ripen over a few weeks, so you’ll need to pick them in stages.

• Ripe berries: Blueberries are ready for harvest when they are fully blue and easily detach from the plant. Avoid picking unripe berries, as they won’t continue ripening after harvest.
• Harvesting tip: Gently twist or pull the berry to avoid damaging the plant.

Winter Care

Blueberries are hardy, but in particularly cold winters, you may want to protect the plants from frost.

• Mulch: Apply a layer of mulch around the base to protect the roots from freezing temperatures.
• Containers: If growing in pots, move them to a sheltered area or insulate the pots with bubble wrap to prevent the roots from freezing.

Troubleshooting

• Yellowing leaves: This can be a sign of nutrient deficiency, often caused by alkaline soil. Correct the soil pH or use an ericaceous feed.
• Poor fruiting: Insufficient sunlight, poor pollination, or incorrect pruning can reduce yields. Ensure your plants receive adequate sunlight and are properly pruned.

Our fruit comes in a wide range of sizes to suits your style and budget. 9cm pots are young plants offering great value and will need to be potted in larger pots to grow on. Plants in 1L to 5L pots are more mature and can be planted straight into their final position. The larger pots are more mature plants, which will produce more fruit in their first season.

Use ericaceous compost and fertilisers for acid-loving plants.
