Fruit
Tree Shapes 26

Pruning promotes
growth and this is used to good advantage when
shaping a fruit tree.
When growing fruit the trees may be trained
in an amazing range of shapes. Some such as
fan trained are ideal where the fruit is to
be grown against a warm, sheltered wall. A sunny
wall will ensure that the fruit skin colours
well and ripens early. Others, such as cordons,
are suitable for small areas and yet more, such
as goblet trees, are really grown for the pleasure
of pruning and training.
The final shape, elaborate or simple, revolves
around how the tree is pruned. Suitable examples
are where you prune to a growth bud pointing
in the direction you wish the shoot to grow,
removing shoots where there is congestion, encouraging
the tree to produce more fruit buds at the expense
of additional growth and renewing old branches
with new growths. The framework branches that
will serve the tree for decades are formed in
the first few years.
Bush The traditional tree shape and suitable
for most types of tree fruit. The framework
of branches spread out like the spokes of a
wheel from the trunk at a height of 1 metre
above soil level. The centre of the bush is
kept free of branches.
Half-standard This is a bush tree on a taller trunk.
It makes a large tree with the additional problems
of maintenance and fruit picking.
Standard As
before but with a trunk 2 metres in height before
the branches spread. This size of tree has to
be grown on a vigorous rootstock. There is certainly
no difficulty using a ride-on mower to cut the
grass under the branches!
Cordon The shape is best suited to apples
and pears planted in a small space. The single
stem is grown at an angle and supported with
a stake or tied to horizontal wires. The growth
is restricted by regular pruning resulting in
quality fruit easily ripened in the sun.
Double cordon Unlike the single cordon the two-stemmed
tree is usually trained vertically with the
twin stems 60 cm apart. French nurserymen used
to produce cordons with up to four branches
resembling overgrown digging forks.
Espalier The horizontal branches are trained
in pairs one on either side of the main trunk.
The tiers are uniformly spaced. Ideal for apples
and pears growing against a wall.
Fan This shape is suitable for most tree
fruit but is ideal for wall grown peaches, nectarines,
figs and cherries. The trunk forms two branches,
one heading to either side and close to the
ground. From these two arise the side branches
that form the bones of the fan.
Stepover This is an unusual tree formed from
a single cordon bent over and trained on a wire
horizontally 30 cm from the ground. It may make
an attractive low edging to a path but picking
the fruit is as sore on the back as picking
strawberries!
