How to Top Citrus Trees

Perform heavy cutting in February before the citrus tree starts growing in the spring. Although you will lose some fruit, this is the best time to preserve as much crop as possible. Topping in February allows the tree more time to heal, there is less chance of winter injury and it's easier to identify flower buds.

Climb a ladder wearing eye protection. Hold a chainsaw or hedge clippers horizontally, with the glade laying sideways. Cut straight across the top of the tree. Gas trimmers have more power than electric trimmers and will cut through thicker, older wood easier. Trim the branches back to promote new growth and a bushier appearance.

Prune the tree canopy annually after it fruits. Remove branches that are crossing or rubbing against each other. They are clogging up the air flow from reaching the entire tree. According to Virginia Cooperative Extension website, cut off branches in the top half of the tree that have a diameter half the size of the trunk diameter.

Cut off weak, diseased or damaged limbs as soon as you notice them. The University of Arizona Cooperative Extension website recommends making the cut a few inches into healthy, green branches.

Cover exposed wood with whitewash or diluted latex paint. Sealing the wound will protect the tree from the sun.
