Pruning By Numbers


Pruning an apple tree can be a daunting prospect, but try not to give into your fear.  Planting a tree and walking away to leave it to its own devices is not advisable. Trees that are not pruned will produce less fruit over time and the branches will become congested and diseased. Pruning does not need to be complicated. Taking time to understand the theory behind it certainly helps. It’s also useful to bear in mind the number 3. You’ll be surprised how often it turns up when you are making your pruning decisions.

Framework branches

The purpose of pruning in the early years of a tree’s life is to create a good structure of framework branches. These support the smaller side branches that will eventually produce the fruit.

To train a one or two-year-old tree into a standard with a 2 metre clear stem it is necessary to let it grow to about 3 metres in height. The top is cut off to just above a bud at approximately the 2 metre mark. This is carried out in the winter. The following spring, three shoots should develop from the three topmost buds.

Forming the trunk

In the first winter – usually at planting time – any side shoots, or feathers, should be cut back to three buds. In the second and subsequent winters, previously pruned feathers are cut back to the trunk and new feathers are cut back to three buds. This process of progressively shortening and removing side shoots encourages the stem to thicken and build a strong trunk.


Controlling the size of the tree

Where branches have become too long, cut these out completely either to the main trunk or, preferably, to a lower, wider angled, outward facing branch. This branch should be one-third the diameter of the branch being removed.


Canopy removal

It is good practice not to remove more than a third of the canopy in younger, more vigorous trees. [In old declining trees this should be restricted to 25%.]
