Prune apple tree after storm damage: repair broken branches step by step

TL;DR

After storm: wait one day before pruning (tree is in shock). Saw off broken branches flush at the base. Remove hanging, peeling bark. Not all at once, but repair in phases over three years. No wound dressing on cuts.

What does storm do to apple trees?

Storm breaks branches in two types of damage: break (branch still hanging) and snap (branch completely severed). Snow load also breaks, but slower and more carefully.

Large branches half-severed hanging are life-threatening. They can break further in wind and injure someone. This must be gone first.

Bark that is torn heals slowly. If bark completely peels, that part of the branch is dead. That must go too.

How quickly must you act?

Immediately after storm (day 1): Ensure safety. Remove heavy hanging branches so no one gets hurt. Do not make pruning wounds yet.

After two to three days: The tree is no longer in shock. Now you can really prune. Do not wait longer as open wounds can begin to rot.

Many gardeners make the mistake of immediately removing everything. This punishes them with water sprouts. Waiting two to three days is important.

Step 1: Assess the damage

This sounds obvious, but many people see only the large branches and miss the real problems.

Walk completely around your tree. Look for:

• Half-severed branches: Branches still hanging but broken. This is life-threatening.
• Loose bark: Strips of bark peeling from the wood. That part is dead.
• Splinters and frayed edges: Rough edges showing open tissue.
• Crushing in the wood: Compressed fibres meaning a break happened there.

Make a list of what must go and what can stay.

Step 2: Remove dangerous branches first

Start with the worst things. Branches half-severed and hanging must come off. This is priority one.

Saw off carefully with a pruning saw (not chainsaw, too rough). Saw flush to the branch collar (that swelling where branch originates). Two centimetres from the collar is fine.

Use a sawhorse or get help. Falls after storms are not funny.

Step 3: Remove dead bark strips

Bark that has separated from the wood cannot grow back and damages the tree. Remove it carefully.

Grab the loose bark edge and pull. It will come off. Do not do this with force, but carefully. You do not want to damage the healthy wood underneath.

Sometimes loose bark sits under damaged branches. Make sure you remove that before sawing off the branch.

Step 4: Saw off large break points cleanly

Where branches are broken (not snapped, but broken wood still attached), it will dry and rot. Saw this off.

Saw flush to the break base, or remove the whole branch if the break is too large. Better a cut wound than dead wood slowly rotting.

If the break is small and clean (no splinters), you may leave it. Large breaks must come off.

Step 5: Cut back what will grow as a second leader

After severe storm you sometimes have branches where the bottom is good but the top broken. Cut the top back to where the wood is healthy.

This helps the tree recover better. You stop the drying, and below starts clean growth.

Do not cut more than necessary. If ten centimetres of the top is broken, cut ten centimetres. Not twenty.

Step 6: Let damaged trees rest now

Now the worst is off, you let your tree rest a bit. This sounds odd, but a tree just heavily pruned is in shock. Extra pruning now makes water sprouts and problems.

Recovery phase one (after first pruning wound):

• Wait two to three weeks.
• Monitor for water sprouts (see other article if it happens).
• Water regularly if it is dry.

Recovery phase two (five weeks later):

Now you can slowly clean up further damage. Small things still present, small branches half broken. Do this in steps.

Recovery phase three (two to three months):

More serious structural pruning. Reform the canopy if needed. But do this next season, not now.

Step 7: Plant strong young branches for the future

After the tree is recovering (about three weeks), you gently start stimulating growth again.

Make sure you have one to two strong young branches in good positions to become new main branches. These can grow from selective water sprout retention, or from sideways growth of remaining branches.

Focus energy on those two strong branches. Removing all competition below them helps them grow stronger.

Crown damage: how bad is it?

This determines your approach.

Mild (less than 10% branch volume gone):

Saw only the damaged part. Then wait one season before doing other pruning. No hurry.

Moderate (10-30% branch volume gone):

Saw damaged parts off. Wait four to six weeks. Then slowly begin cleanup of smaller problems. Plan structural repair for next season.

Severe (more than 30% gone or major main branches broken):

Your tree really needs help. Saw off the worst now. Wait at least three weeks. Then begin phase two of recovery. Over two to three years recover carefully.

With very severe damage (more than sixty per cent gone, or multiple main branches gone) your tree may not really recover and might be better replaced.

What to avoid after storm damage

No chainsaws:

Chainsaws are too rough for fine storm repair work. Use a pruning saw. This is more precise and damages less tissue.

No wound dressing:

This does not help and may promote rot. Leave wounds open. The tree heals itself.

No hard pruning immediately:

Hard pruning now makes water sprouts. Wait and do it carefully.

No neglecting water:

After storm damage, a tree is weakened. Water helps recovery. Water if it is dry.

Specific varieties and storm sensitivity

Cox's Orange: Brittle wood, breaks easily. After storm, more care needed.

Jonagold: Strong branches, less brittleness. Reasonably storm-hardy.

Golden Delicious: Moderate. Strong core, but somewhat weaker lateral branches.

Gala: Relatively strong. Reasonably storm-hardy.

Braeburn: Strong wood, good storm-hardy. Little damage after normal storm.

Rebuilding over years

If your tree is severely damaged, recovery is a two to three year project.

Year one (now):

• Saw off the worst.
• Let rest and recover.
• Encourage one to two strong branches for future.

Year two:

• Former water sprout (selectively retained) develops into strong branch.
• Begin slow formation of new crown.
• Light pruning only, no major changes.

Year three:

• New crown is about two-thirds of plan.
• Normal pruning can resume.
• Tree starts to fruit again.

This takes time, but many trees that look severely damaged recover if you are patient.

Frequently asked questions

How much branch volume can you remove after storm?

In the first pruning round (day two to three): only damaged parts. Not more than necessary.

Total you may not remove more than thirty per cent of the tree in one year. More than that is too much stress.

Can you prune storm damage in autumn?

No. Autumn pruning stimulates growth next spring. Wait until spring (March-April) for structural work. For acute danger (hanging branches) in autumn, prune for safety.

How long does full recovery take?

Mild damage: one season.

Moderate damage: one to two seasons.

Severe damage: two to three seasons.

Very severe damage: possibly not complete.

Can birds and diseases enter the open wounds?

Minimally. Open pruning wounds heal quickly in apple trees, especially in spring. Diseases do not just enter. Leave them open without dressing.

What if your tree looks very weakened after storm damage?

This is normal. The tree recovers slowly. Water regularly in drought. Add compost in spring. Wait at least two seasons before making heavy decisions.

Hope for damaged trees

Many trees that look really damaged after storm recover well. An apple tree is tough. No hurry, wait patiently, and your tree grows back.

The first steps are safety (hanging branches off), then waiting, then careful recovery. This system works.
