How to prune a fruit tree in fan espalier form: complete guide

TL;DR Fan espalier pruning

Fan espalier spreads all branches flat as a fan from the central stem. Perfect for walls and trellises. Choose a young tree, bind branches at low angles, prune side shoots annually. After 3-4 years you have a flat, productive fan with 15-20 main arms.

What exactly is a fan espalier?

A fan espalier is a fruit tree grown flat against a wall, fence or trellis with all branches radiating outward like the ribs of a fan. Every branch grows horizontally and forward - none grow straight up. This is perfect for small gardens: you get abundant fruit in minimal space, and all fruit sits in full light.

Fan espalier works for apple, pear, plum and even cherry. Pears do best - they grow steadily and accept training well.

Why a fan? Because all branches receive equal nutrition, everything grows uniformly. There is no "dominant leader" like an open tree. Every branch produces fruit. And because everything is flat against a wall, you can see exactly which branches to prune even in winter.

Step 1: Choose the right tree

Start with a young fruit tree, ideally two years old (preferably a feathered or partially-branched maiden from the nursery). A tree with existing mature branch structure is harder to train.

Best cultivars for fan espalier:

• Apple: Elstar, Cox, Braeburn, Gala
• Pear: Conference, Doyenne du Comice, Beurre d'Anjou
• Plum: Victoria, Czar, Stanley

Ensure your support structure is ready: a wall, garden fence or wire frame at least 30 cm from the wall (air circulation).

Step 2: Plant and cut the leader back

Plant in March or November. Cut the central stem back to about 40-50 cm above ground. This sounds harsh, but it forces the tree to produce multiple side shoots.

Ensure you have two strong opposite side shoots at the base of this cut stem. These become your two primary "arms" of the fan.

Step 3: Build the base in year 1

During the first growing season (May-August), your tree produces many side shoots. Select two strong, opposite shoots at roughly the same height - these become your first two main arms.

Tie these two shoots downward to about 35-40 degrees angle to the left and right. Use soft twine or plant ties. Do not make them perfectly horizontal - they should still point slightly upward.

Remove or cut back all other side shoots to 5 cm. These will serve as secondary branches later.

Step 4: Add the next layers (year 2)

In March of year two, continue building. You now have two base arms. Find the two or three best side shoots on each arm, evenly distributed. These become your next "layer" of branches.

Tie these new branches downward to about 40 degrees. Ensure they point left and right, not toward each other.

Cut back all other side shoots on these arms to 5 cm.

Step 5: More branches form (year 3)

Repeat the same pattern. You add layer after layer. A mature fan has 15-20 main branches, all radiating outward.

After three years your fan looks like this:

• A short central stem (the center)
• Left and right two base arms at about 40 degrees
• Two to three sub-branches on each arm
• Two to three tertiary branches on each sub-branch
• All branches point forward, none backward

Annual maintenance: summer pruning

From year 4 onward, most work is summer pruning (July-August). This is more important than winter pruning for a fan.

In July:

1. All young shoots growing straight up, cut back to 5 cm.
2. Shoots growing backward (toward wall), remove them.
3. Shoots in awkward positions, bend downward or cut back.
4. Leave all lateral shoots for next season growth.

In March (winter pruning):

1. Dead or broken branches, remove.
2. Crossing branches, remove one.
3. Anything growing inward toward center, cut back.

Fruit production

In year 3-4 you see first fruit. By year 5 you have full crop. A mature 2x2 meter fan can bear 30-50 kg fruit per year - much more per square meter than open trees.

Thin fruits if you see heavy clusters. This gives you larger, sweeter fruit.

Frequently asked questions

Can I grow a fan against a shed or garage?

Yes. Just ensure water does not run directly off the roof onto branches. If against a wall, maintain 20-30 cm distance for air circulation.

How long until a fan becomes productive?

3-4 years to build full structure. But in year 2 you already see some fruit.

Can I convert a fan to another form later?

Difficult. Once trained as a fan espalier, a tree is reluctant to change. You cannot easily return to open form without removing many branches.

What tools do I need?

Pruning shears, saw, soft twine or plant ties, and patience for bending branches downward.

Do I need to fertilize for fan training?

Yes. Add compost in March, some balanced fertilizer in May (e.g. organic fruit tree fertilizer). A fan grows intensively, many branches at once, so nutrition helps.

Step-by-step

Step 1: Prepare and plant

Build your support or identify your wall location. Plant the young fruit tree in March or November.

Step 2: Cut back to 40-50 cm

Cut the central stem to 40-50 cm immediately after planting. This forces side shoot production.

Step 3: Select the two base arms

In May-June select two strong opposite shoots. Tie them downward to 35-40 degrees.

Step 4: Add layers each year

Year 2-3: Add two to three sub-branches per arm, all tied downward.

Step 5: Maintenance pruning

Year 4 onward: July summer pruning (vertical shoots back to 5 cm), March winter pruning (crossing branches removed).

Frequently asked questions

What if my wall is very long? Can I make the fan wider?

Yes. You can extend a fan to 4-5 meters wide by adding more base arms. This takes 4-5 years though. Ensure branches do not crowd too densely - disease spreads faster.

Do insects damage fan espalier?

Very rarely. Fans are actually advantageous because you see everything clearly and can treat problems. The open structure prevents many fungal diseases.

How do I recognize wrong growth?

Branches growing straight up = wrong. Branches growing backward = wrong. Branches crossing each other = wrong. Anything not radiating forward = prune or rebend.
