Plant care & info
Full Sun.
Well-drained, acidic soil in full sun is essential. Although our native soil in Portland is somewhat acidic, blueberries prefer an even lower pH of 4.5 to 5.5. Use cottonseed meal, organic fertilizers for acid-loving plants or soil sulphur to lower pH. Do not use aluminum sulphate for this purpose.
Blueberry varieties grow to different sizes, but on average, plant 3 feet apart for a hedge, 4-5 feet apart for shrubs. Strip flower buds when planting to encourage first year growth. Good air circulation is essential for preventing fungal issues.
Two applications per year of a balanced fertilizer for acid loving plants are recommended. Apply the first dose in early spring when the buds begin to swell. One month later apply the second dose. Follow the directions on the package to determine dose.
Blueberries do not need pruning for the first 1-2 years. On older plants, pruning encourages larger fruit and facilitates air circulation, which prevents disease. An ideal time to prune is in early spring (February or March) when bushes are still dormant.
Blueberries produce fruit on one year old wood which arises from four to six year old stems. To increase this type of growth, cut back the ends of twigs to the point where fruit buds are widely spaced. Remove some of the oldest branches to the ground each year.
Lowbush varieties can be pruned by shearing back half of the plant every two to three years.
Most highbush blueberries are self-fertile, but they will produce bigger crops and larger fruit when planted with a different variety. Lowbush and half-high varieties require pollinators. Check our pollination chart for details.
Harvest: Blueberries are divided into 3 classes by fruit ripening time, and harvest season can be extended by planting a variety of them.
- Early Season: Fruit ripens in early to mid-June.
- Mid-Season: Fruit ripens mid-July.
- Late Season: Fruit ripens July into August.

In addition to being a delicious garden treat, many blueberry bushes offer stunning fall color, while others remain evergreen–making them an excellent and versatile hedging option. For those with limited space, consider planting your blueberries in a container.Â
