When to plant blueberry bushes

The best time to plant blueberry bushes in the UK is in the autumn or early spring, when the soil is cool and moist. This allows the roots of the bush to establish themselves before the hot summer months. If you're planting in the autumn, be sure to give the bush enough time to get established before the first frost.

Blueberries need a sunny spot that’s protected from strong winds. They prefer acidic soils with a pH between 4.5 and 5.5. If your soil isn’t naturally acidic, you can add sulphur to lower the pH, or plant in a container of ericaceous compost. 

It’s also important to make sure your planting site is well-drained and rich in organic matter. Blueberries don’t tolerate soggy soils, and won’t do well in soil that’s compacted or clay-like. Adding compost or well-rotted manure to the soil can help improve its structure and fertility.

When planting blueberry bushes in the ground, dig a hole that’s twice as wide and deep as the root ball. Remove the plant from its container and loosen any compacted roots. Place in the hole and backfill, making sure the root ball is level with the surrounding soil. Water your plant in, and then continue to give your blueberries a deep watering once a week to keep the soil moist and prevent the formation of shallow roots. Add a layer of mulch around the base to help retain moisture and suppress weeds.

If you have enough room, it’s always a good idea to plant more than one blueberry to help with pollination. Space them at least one metre apart to allow air and sunlight to penetrate. If you’re growing a compact lowbush variety like blueberry ‘BerryBux’ as an edible hedge, the plants can be positioned slightly closer together. 

Blueberries typically begin to bear fruit 3-4 years after planting. By removing all the flowers from your newly planted bush in the first year, you can prevent it from fruiting and divert all its energy to putting on more fruiting wood.

Blueberry plants can also be grown in containers, making these ornamental edibles a great option for small gardens or patios. Choose a wide container that’s at least 50cm deep, and make sure it has drainage holes. 

Fill the container with a mix of ericaceous compost and sharp sand. Plant the bush at the same depth as it was in its previous container, and water well.

How to care for your blueberries

Blueberries require regular watering, especially when they’re flowering and fruiting. Use rain water whenever possible, as tap water can change the pH level of your soil over time. A thick layer of mulch around the base of the bush will help to retain moisture.

From April to September, feed your container-grown plants once a month with a liquid ericaceous fertiliser. For plants growing in the ground, simply apply a high nitrogen feed once a year in February or March. Always follow the instructions on the packet as blueberries don’t like to be overfed.

Pruning is an important part of blueberry care, as it helps to promote healthy growth and a bountiful harvest. The best time to prune is late winter, while the plant is dormant and before new growth begins. Old canes should be removed, and the remaining canes should be thinned to allow for good air circulation. Find more specific advice, along with a helpful video, in our blueberry pruning guide.
