Monstera deliciosa, also called Swiss cheese plant, is a large tropical plant growing more than 15 feet tall. The leaves are large, green and glossy with slits or round holes. This plant is hardy down to USDA zone 10, which means it only survives the winter outdoors in areas where the temperature stays above 40 degrees F. As a result, most of the time the Monstera deliciosa grows as a houseplant. In order to keep it healthy and in check you must prune it regularly.
Examine your Monstera deliciosa tree. Look for any yellowing leaves or signs of disease. If you find this, or if you think the tree is too large for its space, it is time to prune.
Sterilize your pruning shears before using them. Monstera deliciosa is susceptible to bacterial leaf spot, which could transfer from contaminated shears. Dip the blades in rubbing alcohol to clear them of bacteria and fungi.
Prune out yellowing or diseased leaves as you see them. Make a straight cut across the stem, cutting off all infected parts.
Prune the tree to keep it within bounds. You may prune it as much as you wish. The plant will survive and produce new shoots in a couple of weeks. Again, make straight cuts across the branches.
