Blueberries,
Cranberries
and
Other Vacciniums

Horticulturist
Jennifer Trehane,
a professional berry grower in Dorset, England, penned this handy
reference
to vacciniums for the Royal Horticultural Society's Plant Collector
Guide
series.
"For the
purposes of this book, the
botanical descriptions of what I would call the 'cooler climate'
vacciniums
are given, as are those that are native to North America and Europe and
have been the subject of study over many years, as well as those that
have
garden merit or are in cultivation as food crops," Trehane explains.
Many
rare, unusual, neotropical or tropical species of vacciniums are not
covered
in this text.
Following
an introductory chapter
on the genus vaccinium, Trehane devotes three separate sections of the
book to Cranberries and Lingonberries, Blueberries, and finally to
Vacciniums
as Garden Plants.
In the
Blueberries section, Trehane
sorts out the distinctions between the "lowbush" varieties common to
New
England and eastern Canada and the "highbush" blueberries of New
Jersey,
as well as the "southern highbush" and "southern lowbush" berries of
Australia
and New Zealand.
"Cultivated
northern highbush blueberries
are regarded as the Rolls Royce of blueberries," Trehane points out.
"They
are larger and have greater eye appeal than lowbush or wild
blueberries,
although many would say that the latter's smaller size produces a more
concentrated blueberry flavor."
In
addition to its bountiful advice
and instruction on the cultivation of edible blueberries, cranberries,
lingonberries and many of their relatives, this book also provides
guidance
on controlling pests and avoiding disease.

| Constructing
a Berry Bed (pg. 198-201)
Berry
beds provide
a most attractive ornamental feature in any garden, large or small, and
can be inexpensive and easy to construct. A more permanent,
high-quality
structure can make a big difference to an otherwise unremarkable
garden.
Raised beds filled with suitable compost provide the special conditions
needs for all ericaceous berry plants, enabling gardeners who do not
have
the naturally acidic free-draining soil needed for these plants to
widen
their horizons and to enjoy both their edible fruits and the year-round
ornamental interest.
Berry
beds can be of
any size or shape and be designed to the scale of the garden and
owners'
taste. Different materials can act as soil-retaining edging.
A
bed with a surface
areas of about 7 sq. ft. (2 sq. m) should accommodate two of the more
compact
North American highbush blueberries, one southern highbush and one or
twol
half highs. At least 6 cranberries and 12 lingonberries can be added to
cover the ground. A flat stone placed here and there will mean not
trampling
on the cranberries when harvesting the blueberries.
1.
Mark the outline
of the site to be constructed. The shape can be square, rectangular,
circular,
semicircular or any other shape that fits in with the existing or
planned
design of the site. A basic bed to suit most situations is 6 ft. x 6
ft.
(1.8 m x 1.8 m) and about 3 1/3 ft. (1m) deep.
2.
Dig out up to 12
in. (30 cm) of the soil within the marked-off area. Retain the soil and
mit it later with organic ingredients if its pH is 6.0 or less. Remove
the soil if the pH is above 6.0. If building a retaining wall of stone
or brick, lay foundations and build the wall, leaving drainage holes.
If
using log rolls, split poles, wooden boarding or planks of wood or
other
material, you will need to incorporate vertical supporting posts.
3.
Mix the materials
that will form the compost and fill the bed very near to the top of the
retaining wall, bearing in mind that organic matter will shrink as it
decays.
4.
Plant up the bed
and water it thoroughly.
5.
It is a good idea
to plan for when the fruit appears. When the blueberries begin to show
the slightest color, they must be protected from birds and berry-eating
mammals. Either purchase or build temporary fruit cages that allow
access
and remove them once the crop is harvested.
