Pruning a Mature Monstera Deliciosa: Step-by-Step Guide

When a 25-year-old Monstera deliciosa (often called split-leaf philodendron) outgrows its space, strategic pruning can rejuvenate it without killing the plant. The key is understanding that Monstera responds well to hard pruning, unlike its lookalike Philodendron selloum.

How to Prune Successfully

Cut each stem back to just above the lowest leaf node. This encourages the plant to send out new shoots from lower on the woody stem. If you cut below the lowest leaf, you risk losing that stem entirely, though it may still resprout. Spring is ideal for this work since the plant enters a natural growth surge as days lengthen, but pruning can be done year-round—just expect slower regrowth in winter.

What to Expect After Pruning

The plant may appear dormant through winter, with new growth emerging once daylight increases. Don't panic if nothing happens immediately. The established root system will support vigorous regrowth when conditions improve. For a plant this old with arm-thick stems, the transformation can be dramatic and rewarding.

Identification Matters

Before pruning, confirm you have Monstera deliciosa (with iconic perforated leaves) rather than Philodendron selloum (deeply lobed but solid leaves). The two require different approaches, so proper ID is essential.
