Prickly pear and other pad cacti need little or no pruning, and when you must cut, make the cuts at the joints between pads and wear protective equipment. Arizona State says of Opuntia macrocentra that none is really needed, but if one must prune, make sure to wear proper protective equipment. The University of Nevada, Reno says to make all cuts at the joints where the pads connect and that the plant should never have portions of the pads chopped off. This guide covers prickly pear (Opuntia, and Cylindropuntia in the Nevada guidance) and sits under our cactus care guide and prickly pear guide.

Do you need to prune?

NC State says pruning is not generally required for Gymnocalycium, which our care guide covers. Arizona State says the same of Opuntia macrocentra: none is really needed. Holiday cacti are the exception, because the sources prune them to encourage branching. See our Christmas cactus pruning guide for that.

How to cut a pad cactus

Cut at the joints

University of Nevada, Reno says to make all cuts at joints where the pads are connected. The City of Chandler, Arizona says the same: if needed, make pruning cuts at the joints.

Never chop a pad

University of Nevada, Reno says this plant should never have portions of the pads chopped off.

Keep the natural form

University of Nevada, Reno says the natural form should be maintained, and topping or hedging does just the opposite.

Prune selectively

Chandler says the most widely recommended technique is selective pruning. Shearing and excessive pruning compromise vigor and health, reduce blooming and may shorten the life of the plant.
  1. Put on protective equipment. Arizona State says to wear proper protective equipment if you must prune. NC State says to wear gloves, and UF/IFAS says pads and fruit have glochids that stick to skin.
  2. Choose the pad to remove. Work selectively, pad by pad, rather than shearing the plant (Chandler).
  3. Cut at the joint. Remove the whole pad where it connects (University of Nevada, Reno, Chandler).
  4. Leave the rest of the plant's shape alone. Maintain the natural form (University of Nevada, Reno).

How tall to keep it

The University of Nevada, Reno says Opuntia and Cylindropuntia can easily be pruned to several different heights, depending on what you want the plant to do in the landscape. Our prickly pear guide lists a wide range of mature sizes, from 3 to 20 feet tall in NC State’s description of the genus, down to 6 to 12 inches for the eastern low prickly pear. Check the size of your species before deciding to prune for height.

If you want seeds or fruit

The University of Nevada, Reno says that if you want to save seeds for propagation or as food for wildlife, prune after the seeds are mature or dispersed.
