First things first: it is pronounced
es-PAL-yay, or es-PAL-yer, not espa-LEER. Choose –yay or –yer, and stick with it.
Espalier is not difficult, but it requires
patience, and sticking to a training plan for the life of the tree. The
training plan itself requires cutting off perfectly good branches and
sacrificing some fruit for the common good. To successfully create an
espaliered fruit tree, be ruthless. The trees don't mind. And they will produce
bucket loads of fruit.
Fruit trees can be planted in October in zone 7, or in
March and April. Fruit trees that are grafted onto dwarf or semi-dwarf
rootstock make the best espaliers. Purchase one-year-old trees (called one-year
whips), preferably with no branches. When choosing a site for an espalier, keep
in mind that fruit trees need six hours of sunlight a day, and a southern or
western exposure is best. Space multiple trees six to eight feet apart. In the
first season, water weekly, and twice a week or more in hot weather.Train the tree on a structure of wire supports. To create an
espalier against a wall, secure two 4'x4' posts into the ground six feet apart,
eight inches from the wall, to allow air flow and to give the trunk room to
grow. Screw eye screws into each post two or three feet from the ground. Thread
galvanized 14-gauge wire horizontally through the eye screws to create the
lowest tier. Now screw in eye screws 18" to two feet up from the first and
thread in the wire to create the second tier. Continue up to create additional tiers.
This structure also works well as a free-standing trellis.
Here is the
hardest part: making the first cut. When the tree grows to two inches above the
first tier wire, cut off the top of the tree right above a bud. The plant will
start producing branches near the first tier wire. Once the branches reach six
inches long, choose the two strongest and attach them loosely to the first tier
support wire. Use a material that won't cut into the branches, such as strips
of Velcro or cloth. Do not use wire to tie espalier branches to the support
wires.
Remove any branches that grow below the tied branches. Continue to tie the branches to the support wire every foot or so as the tree grows.
As the growing
season progresses, keep the center trunk six inches above the first tier. Prune
it back as it grows to keep it at the six inch limit.
When the bottom tier branches are three-quarters of the way to the end of the wire support, allow the central trunk to grow to six inches above the second tier, and start the process again. The tier branches will grow shoots where the fruit will form, called spurs. Keep the spurs cut back to five or six inches long.

The tier branches will grow shoots where the fruit will form, called spurs. Keep the spurs cut back to five or six inches long.
For the first two years, prune off all the fruit. The first
and second years of growth need to be focused on root, branch, and leaf
production to get the tree completely established. Removing all of the fruit
may seem even more severe than cutting off the top of the tree. Just do it.
In the third season and thereafter, remove all but the one
best fruit from the clusters of three or four that form. The joy of espalier is
harvesting large perfect pieces of fruit. Espaliered fruit trees reach their
prime in four or five years, and can to bear fruit for up to or beyond 25 years.
Keep the espalier instructions handy for a few years until
the process becomes second nature. Remember patience is a virtue. It is worth
it.
Best fruit trees for espalier:
Any apple
variety can be pollinated by any other variety if they flower at or near the
same time. These three can be self-pollinating, and they all pollinate one
another:
McIntosh: Most adaptable to any espalier design; very hardy, fruits
ripen late in the mid-season.
Spitzenberg: Old-fashioned variety; makes very nice Palmette Verviers,
horizontal cordons, and fans.
Empire McIntosh
type apple but keeps longer. Ripens two weeks after McIntosh.
Pears are not
usually self-pollinating, so when possible plant two varieties. Pear branches
are not as pliable as apple branches, but they do make lovely espaliers.
The plum tree 'Stanley'
is self-fertile and very productive. It is a medium to large plum from Europe that
is excellent for eating fresh, cooking, or canning.
