Pruning Citrus Trees

Citrus trees don’t technically need to be pruned, however, if you leave them to grow wild they will grow large as well and their branches will overtake an entire section of your garden. This will mean that dealing with pests and even collecting fruit will become difficult to manage. Therefore, pruning citrus trees annually is a better idea.

The best time for this is late winter to early spring in frost-free areas, and in areas where you do get frost, wait until the frosts have finished in late spring. This will help you keep your citrus compact, producing a high yield of fruit and maintaining a healthy tree.

New Trees

With a new tree, when pruning you are helping it to establish the shape that will provide you with the most fruit. Slow growing horizontal branches tend to produce the highest yield of fruit so encourage these and cut back the vigorous upward growing branches that tend to take a lot of the tree’s energy but produce little or no fruit. If you have a lot of fruit in the first couple of years, thin it out to allow the tree energy to continue to establish and grow.

Established Trees

For an established tree when you are choosing what to prune, keep in mind the highest yield of fruit will come from the outer parts of the tree.  If you prune these heavily you will reduce your yield for that year. The best way to deal with an established tree is to look at the tree and prune the branches that are the longest and will improve the overall shape of the tree. As these branches will produce less yield this year, only prune approximately one-fifth of the branches of the tree. This will leave the other parts of the tree to produce fruit and over a number of years, you will have pruned the whole tree without overly affecting your fruit production.

When pruning, try to keep the tree to a manageable height by pruning the upward growing branches.  Prune low hanging branches also as any fruit that grows on these and that comes in to contact with the soil can lead to fungal activity and fruit that is diseased.

Don’t forget to keep standing back and assessing the overall shape.  You are looking to achieve a half circle shape above the trunk.

Citrus Tree Revival

If you have an old citrus that is rangy (tall and slim with long slender limbs), low yielding and unhealthy, you’re going to need to do a bit more work. You will need to remove all the branches, leaving only the trunk and healthy branch stumps. Be careful as you do this work. Citrus is likely to have sharp thorns so remove branches in sections and make sure you are wearing protective clothing. For thicker branches, make sure you cut them using a sharp pruning saw. This will help you to reduce the chance of creating a large wound in your tree by the branch splitting and taking away part of the trunk.

Once all of the branches have been removed, you need to protect the tree from the sun so gently wash the trunk to remove any lichen and dirt and then paint it with a lime-based whitewash. You should start to see fruit returning to the tree within a couple of years.
