Growing Blueberries
The blueberry (Vaccinum hybrid) is a deciduous shrub in the Erica family and
native to the eastern United States. It is related to the Rhododendrons, Ericas,
Manzanitas, and Azaleas. They are handsome hedge or shrub plants, usually growing to
about 6'. In the autumn, the leaves turn brilliant scarlet , orange and yellow. The flowers
resemble those of the manzanita, dainty white or pink urn shaped blossoms with a light
fragrance in the spring.
Like its cousins, it needs acid, well- drained soils. Blueberries thrive in full to part
sun but their roots like to stay moist and cool. A mulch, such as redwood compost or
Microbark will help keep shallow roots moist and control weeds.
If your soil is not acidic
enough (Blueberries do best with a pH of 4.5-5.5), amend your soil with ground bark or
EB Stone Azalea Camellia Mix. You can also apply Aluminum Sulphate to acidify the
soil. Blueberries will grow in barrels or containers too! You will want to use acid
fertilizers whether liquid or dry through the growing season.
If yellowing leaves are a
problem, use iron sulfate or iron chelate. Provide frequent water. Space plants 3' apart
for an informal hedge, 4' to 6' apart as shrubs. You can accommodate 2 plants per barrel
or large container.
Plants generally shape themselves but some pruning may be needed to prevent
overbearing. Overbearing results in smaller fruits and slowed growth. On first year
plants, you should strip all the flowers to allow the bush to put all its energy into growth.
On older plants, either remove some of the oldest branches each year or cut back the ends
of twigs to the point where the fruit buds are more widely spaced.
Plant two varieties for
better pollination. Planting at least 2 plants for each season- early ( early to mid June),
midseason ( early to mid July ), and late (late July into August)- will provide berries
through much of the summer. A good rule of thumb for adequate fruit production is to
allow two plants for each member of the family. Most of the blueberries that do well in
our area are highbush varieties. They require definite winter cold. There are also some
relatively new berries that are known as southern highbush. These varieties are better
adapted to areas where the winters are mild. They ripen their fruits from mid to late
spring (late April to June). They also tend to be semievergreen.
Here are brief
descriptions of some of the most popular varieties for our area:
- 'Berkeley' is one of the most popular selections for the home garden. Berries are
medium to large and powder blue with less acid than most. It bears mid season. The bush
has good ornamental value, growing 5' to 6' tall with good autumn color and yellow
twigs in winter.
- 'Bluecrop' is a mid season cultivar and a tall grower. It is considered one of the
best all around for consistant yields. Fruit is large and of excellent flavor. This plant
makes an attractive shrub, upright 4' to 6'. Leaves turn red in fall.
- 'Blueray' produces large, bright blue fruit with outstanding dessert flavor in early
to midseason. The shrub has excellent ornamental value with lovely pink spring flowers,
dark green summer foliage and burgundy red autumn leaves. It grows 4' to 6' tall. It
performs well in areas with hot summers and very cold winters.

southern highbush ripens very early and the shrubs are short 3' to 4', good for containers.

compact grower well suited to container growing, growing 3' tall. A heavy crop of good

The pleasure of eating fruits, herbs and vegetables harvested yourself is so sublime that sometimes mere words cannot do this experience justice. These are the fruits of your gardening labors and you should plan for them. Go ahead and dream of backyard strawberries, tomatoes in containers or herbs sprinkled onto the evening salad because now is the perfect time to get ready for edible gardening.
