How to remove water sprouts on apple trees: vigorous vertical shoots

TL;DR

Water sprouts are thick, upright shoots that grow from old cutting sites after heavy pruning. They are energy thieves that produce no fruit. Remove them in July-August by breaking them off or gently pruning with a small stub, not by cutting hard back (that only stimulates more).

What are water sprouts?

Water sprouts are the thick, strongly upright shoots that suddenly appear, usually from old cutting sites or below damaged branches. They grow straight up like a tree in a hurry. An apple tree can make two metres of water sprouts in two months.

Water sprouts happen because the tree thinks it is damaged or dying and must grow fast to repair itself. It is an emergency response. When you prune an apple tree hard, it sees a hundred cuts and feels threatened. So it sends all its energy to one place and makes water sprouts.

The worst part is that water sprouts have no flower buds and produce no fruit. It is pure foliage and energy. While your nice spurs below get no food.

Why heavy pruning leads to water sprouts

You need heavy pruning after storms, after disease, or to get an overgrown tree under control. But every time you prune hard, you trigger this response. It is the tree's natural defense mechanism.

A tree that is cut back hard every winter sits in constant alarm mode. Every spring: water sprouts. Every year the same problem. This is why some gardeners never really get their tree under control.

The solution is not to prune even harder. The solution is to act quickly on water sprouts as soon as they appear.

When water sprouts appear

Early April: first frost danger past. The tree starts growing. Small papery shoots appear.

Late April to May: water sprouts become clearly visible. Thick, juicy shoots, bright green leaves.

June to July: water sprouts are fully grown, can already be two metres long.

August: this is the time to deal with them.

September and later: too late. The water sprouts have hardened and are difficult to remove. Moreover, autumn pruning stimulates even more growth next spring.

Step by step removing water sprouts

Step 1: Wait until July or August

This is very important. In June, water sprouts are still green and juicy. If you prune now, it only stimulates more growth. Wait until the wood begins to harden. The leaves become somewhat darker green, the stem feels less soft.

July-August: the moment has come.

Step 2: Break them off instead of pruning

This is the old gardeners' trick. With your hands, break off the thick water sprouts at the base. Not neat trimming with pruning shears (that leaves a cut that only stimulates more growth). Break it.

Grab the water sprout close to where it originates. Bend it gently back and forth. Lift gently. Then twist and pull it off. It feels rough, but the tree recovers much better from breaking than from cutting.

This works best on water sprouts that are not yet too thick (thinner than your thumb). Thicker water sprouts you must really prune.

Step 3: Prune if breaking does not work

Thicker water sprouts will not break. Then prune. But prune in the special way.

Saw the water sprout off close to where it originates. But leave a small stub of two centimetres. Do not cut flush. That two-centimetre stub damages itself and heals oddly, preventing new water sprouts from growing out.

This goes against all "clean cutting" rules, but it works.

Step 4: No wound dressing on the cut

Smearing wound dressing on cuts only stimulates more growth because it damages the tree. Leave it without covering.

The big mistake: pruning even harder

This is what most people do, and it does not work.

Gardener sees water sprout. Gardener thinks: "This looks weird, I will prune it back to a nice point." Gardener cuts the water sprout back to twenty centimetres from the base.

What happens? The tree sees: "Oh no, even more damage! I must grow even harder!" Result: next month double the amount of water sprouts.

This is the water sprout trap. The more you prune, the more it grows. Only breaking (not cutting) or minimal pruning (with stub) breaks the cycle.

Prevention better than cure

The best solution is preventing water sprouts. You do this by never pruning too hard.

A tree that is pruned lightly each year (twenty per cent of volume removed) almost never gets water sprouts. A tree that is cut back very hard every three years (fifty per cent removed) gets water sprouts every spring.

So: prune often and lightly, rarely prune hard.

Water sprouts as a sign

If you suddenly get lots of water sprouts, that is a sign you have pruned too hard. This is feedback from your tree. Next years: prune lighter.

Also water sprouts from a certain part of the tree (only below, or only on one side) means something is wrong there. Disease? Damage? Investigate that area better.

Varieties and water sprout sensitivity

Some apple varieties make more water sprouts than others.

Jonagold: Vigorous water sprout maker. Heavy pruning stimulates massively. Treat carefully.

Cox: Low water sprout sensitivity. Reacts mildly to heavy pruning.

Golden Delicious: Somewhat sensitive. Heavy pruning gives a response, but less than Jonagold.

Gala: Moderate. Not worse than average.

Braeburn: Vigorous. Heavy pruning leads to lots of water sprouts.

The water sprout pruning kit

For removing water sprouts you need:

• Sharp pruning knife (for breaking, not sawing)
• Strong legs (because you stand high in the tree)
• Patience (this is not five-minute work)
• Pruning saw (for thicker water sprouts)

No wound dressing, no wax, no mess. Just remove.

Water sprouts as an opportunity

Water sprouts have one advantage: they are strong shoots. If you want your tree to grow bigger, you can let one water sprout stand, shape it, and in two years you have a strong new main branch.

Use this if you want to repair a damaged tree. Let one water sprout grow. Remove all others. That one strong shoot saves your tree.

Frequently asked questions

Can you prevent water sprouts by not pruning?

No. Water sprouts usually come from damage or very old cutting sites. If your tree is healthy and pruned lightly, almost no water sprouts.

But not pruning at all makes your tree wild and uncontrolled. You must prune, but carefully.

How long do water sprouts stay away if you remove them?

If you break properly (no cut wound), they stay away. If you prune, they come back next month. This is why breaking is better than cutting.

Can you use water sprouts for anything useful?

Yes. Remove most of it, but let one or two strong pieces grow if your tree needs extra branches. They are very vigorous.

What if water sprouts are already very old (two years)?

Then it is no longer water sprout, it has become a normal shoot. Prune like a normal branch. It will behave normally.

Must you deal with water sprouts all season?

No. Wait until July-August. That is the only time it really works. Before that: let it grow, it helps the tree recover from your pruning.

The secret of no water sprouts

Many gardeners have trees that make water sprouts every spring. The secret of trees without water sprouts is simple: prune where it prevents them, act fast where they occur.

With this system you will see that your apple tree produces fewer and fewer water sprouts. Over three years: almost none.
