Growing fruit at home allows you to enjoy the joy of reaping the rewards of your efforts, both in process and outcome. If you've planted an apple tree and want it to bear as much fruit as possible, you've probably already researched whether you need to prune it. Pruning helps trees stay healthy, promotes growth, and continuously produces more and better fruit.
Choosing a good quality electric pruning shear will not only improve your pruning efficiency, but also cut flatter for the healthy growth of your fruit trees.
Don’t let your fruit tree grow wild and unruly due to neglect; you can prune your apple tree yourself with just a few simple steps.
Method 1: Mastering the Basics
Step 1: Know When to Prune
When you realize your apple tree needs pruning, you might be eager to start cutting branches immediately. However, it's crucial to prune at the right time to avoid damaging the tree. The first or second month of spring, at least two weeks after the last frost, is the best time to prune.
-
You can also prune in late spring or early summer if needed.
-
Avoid pruning in the fall, as this can stimulate growth that might freeze and die in the winter.
-
Step 2: Decide How Much to Prune
A properly pruned healthy apple tree should have no shade and plenty of space between branches
.
Step 3: Prepare the Right Tools
To avoid damaging the tree, you'll need some specialized tools for pruning. The size of the cutting tool should match the branches you need to prune. Use hand pruners for smaller branches. For branches about 2.5 cm thick, use loppers. For anything over 7.5 cm thick, use a saw (a folding saw works well).
Step 4: Know Which Trees to Prune
If your apple tree has a large canopy, it's clear it needs pruning. However, don’t prune every tree. Only prune fruit trees that are at least three years old. If a tree needs extensive pruning, do it over several seasons.
-
Pruning young fruit trees helps them develop a strong framework and good form.
-
Pruning larger or mature trees helps them produce bigger, healthier fruit and maintain overall good condition.

Method 2: Pruning Your Apple Tree
Step 1: Shape the Tree Well
Your apple tree should be slightly conical, with a broader base than the top. This allows more sunlight to reach the branches. Remember to shape the branches into a pyramid structure.
Step 2: Select Scaffold Branches
As the apple tree grows, it will have a central leader connected to scaffold branches. From the top view, your tree should have only three or four scaffold branches, spaced out without intersecting each other. Depending on the size of the tree, there should be 2-6 main scaffold branches. Prune away the rest.
-
From above, the scaffold branches should look like a star or spokes on a wheel.
-
Step 3: Remove Suckers
Suckers are useless shoots that grow around the base of the trunk. Remove all these below the main canopy to improve the overall shape. Suckers are the only parts that can be pruned in late summer or early fall.
Step 4: Cut Away Deadwood
Remove branches that are dead, diseased, or damaged. If a branch has no buds, remove it entirely. If there are buds near the base, cut just above an outward-facing bud at an angle to let rainwater run off.
Step 5: Remove Crossing Branches
To shape your fruit tree like a vase, cut away any crossing branches. Vase-shaped trees look more attractive, allow wind to blow through the branches to prevent airborne diseases, and get more sunlight, leading to more fruit.
-
Crossing branches can rub against each other and spread disease. Cut these and any inward-growing branches from the base.
-
Step 6: Remove Downward-Growing Branches
If there are branches growing downward, prune them. These branches won’t produce large, healthy fruit and will take up valuable space and sunlight that other branches could use more effectively.
Step 7: Prune Whorled Branches
Whorled branches are common on mature trees and consist of three or more small branches growing from the same spot. These branches are weaker and can't support continued growth. Identify the largest, healthiest branch and remove the others.
Step 8: Prune Remaining Branches
Cut the remaining branches back by half to encourage thicker growth and better blooms for the next season. Each cut should be just above an outward-facing bud to improve the tree’s shape.
Tips
-
As a home gardener, it's crucial to over-prune your apple tree rather than under-prune. Don’t be afraid to cut too much; you’re more likely not cutting enough to keep your tree healthy.
-
Remove all pruned branches, compost them, or use them as mulch.
By following these guidelines, you’ll ensure your apple tree remains healthy and productive.
