Air plants do not usually require pruning as they do not grow roots and are often grown for their unique, natural shape. However, if the plant becomes too large or overgrown, you can trim any dead or damaged leaves with a pair of sharp scissors. Be sure to cut close to the base of the leaf without damaging the main stem. You can also trim the ends of the leaves to keep them looking neat and tidy. Avoid overpruning as it can harm the plant.
