How to prune a plum tree

Pruning plum trees is not difficult, but it is very important. Plums can become very heavy, so when branches are weak this can cause them to break off. Encouraging healthy growth on your plum tree will leave you with a stronger tree and better fruit. Let’s go over the steps of how to properly prune your plum tree.

Timing

Plum trees should be pruned in late winter when the tree is still dormant, pruning in February or March is a good rule of thumb. It’s important not to wait too long to prune because they will quickly start buds in early spring. Plum trees can be pruned at other times of the year but late winter is best.

Pruning a young plum tree

Young plum trees require light pruning to ensure they get a healthy start. Pruning the tree properly when it is young creates a healthy branch structure for the tree to grow from. Using sharp pruners, prune the tree to have 4 or 5 main branches growing off the trunk. It is best to have an arborist prune young trees.

Pruning an established plum tree

For established plum trees, you should also remove any dead, dying, or diseased limbs and remove water-sprouts (vertical fast growing skinny branches). Established plum trees tend to have a crowded canopy, removing some interior branches will allow for more light and airflow through the canopy. Aim for a manageable size and shape, creating an open shape. For professional help, contact an arborist. Ascent Yard Care provides arborist services in Victoria, BC.

Pruning an old & neglected plum tree

Pruning an old or neglected plum tree will require patience. One prune will not instantly bring life back to the tree, so follow the established plum tree pruning method for a couple years and then you should start to see results. Heavy pruning can be too harsh for plum trees, which is why it may take several years of attention for you to see your old plum tree come back to life.
