How to prune a monstera without the guesswork

NC State Extension and the RHS both point to spring for pruning a monstera. General houseplant advice agrees: Clemson Extension suggests a light trim at the end of winter, before spring growth, and Illinois Extension says to cut tropical houseplants back in spring, before active growth.

The real trigger is growth, more than the calendar. NYBG describes active growth from March to September in New York and a slower rest in winter. Where spring comes in September, prune then. In the tropics, where a monstera may grow all year, pick a stretch when it is pushing out new leaves.

New growth comes from the nodes. Illinois Extension defines a node as the point where a leaf attaches to the stem, and University of Maryland Extension explains that a cut just above a node gives the plant a place to send out new growth. Penn State Extension gives the same advice for pothos, a related vine: shorten a stem with sharp scissors just above a node, anywhere along its length.

On a monstera, look where each leaf stalk wraps around the main stem. Penn State Extension notes that the aerial roots form at the base of the leaves, so a brown, cord-like root is a handy sign that you have found a node.

If you want to root the piece you remove, the cut goes the other way: below a node, so the cutting keeps it. Wisconsin Extension cuts the stem tip just below an aerial root, and UConn suggests cutting 3 to 5 inches below a node. Our monstera propagation guide covers that part.

The RHS says to cut off leaves that are moldy, shriveled, or completely yellow or brown, and to keep leaves that are still mostly green until the plant has made new ones. Remove the whole leaf with its stalk, cutting close to the main stem without nicking it. NYBG adds that a yellow leaf that comes away with a gentle tug can simply be pulled off. Clearing dead growth also gives pests fewer places to hide, according to Clemson Extension and University of Maryland Extension.

An old leaf turning yellow now and then is normal. Lots of yellow leaves point to a care problem, often too much water, and the monstera care card and our yellow leaves guide help you find it.

Leggy stems, with long bare gaps between leaves, are a light problem first. Penn State and NYBG both say low light makes a monstera stretch and its new leaves come in small and without splits. Cut a leggy stem back to a node in spring, and move the plant to bright, indirect light so the new growth comes in compact.

I hold on with these. NYBG says healthy aerial roots make the best-looking monsteras and advises against removing them: guide some into a moss-covered pole and leave the rest in the air, where they can take up moisture. Wisconsin Extension also suggests giving them a damp support to grip.

Iowa State Extension is more relaxed about philodendron, a close relative: you can leave the roots, guide them up a pole, push them into the soil to help steady the plant, or cut them off close to the main stem with sharp pruners, which it says won't harm the plant. So if one root is damaged or blocking a walkway, a clean cut near the stem is fine. For the rest, a moss pole puts them to work.

Indoors, a monstera usually reaches 6 to 8 feet, according to NC State and Penn State, and NYBG says a well-cared-for plant can grow well over 10 feet. NC State gives it 6 to 12 feet of space. When it outgrows that, the RHS says you can cut it back in spring. Expect the new stems to carry smaller leaves with fewer holes for a while, until the plant settles.

The pot matters too. UConn says a monstera copes with being pot-bound better than with a pot that's too big, and NYBG suggests that once the plant is as large as you can handle, you replace the top layer of soil every other year instead of moving it up a size. That keeps growth steadier.

If the problem is a plant flopping over more than its size, a sturdy support helps more than shears: NC State says support keeps the heavy stems from breaking. Our moss pole guide covers that fix. And if you want a monstera that stays smaller, the RHS points to Monstera adansonii; our monstera types guide compares the options.

University of Maryland Extension and Illinois Extension say that cutting houseplants back to a node makes them branch, and Penn State says trimming keeps pothos short and bushy. For a monstera, the RHS only says new stems will grow after you cut it back. The photo above shows what that often looks like: one new shoot from a node on a cut stem.

For a fuller pot, root the tops you cut off and pot them up, which our propagation guide walks through. Good light also keeps growth compact, since a stretched monstera looks sparse whatever you cut.

Iowa State Extension recommends 70% isopropyl alcohol for home gardeners: wipe or dip the blades, no soak needed. Its other option is 1 part household bleach to 9 parts water, with the blades soaked for at least 10 minutes, then rinsed, using the mix within two hours. Iowa State says to disinfect at least between plants, and ideally between every cut.

Sap gets in the way, so clean first. Clemson Extension suggests soapy water and a brush to get sap and residue off, and notes that bleach can corrode tools. Sharp blades matter too: Penn State Extension prefers bypass pruners, which slice cleanly, because anvil types can crush stems.

Wisconsin Extension roots stem tips cut just below an aerial root, and the RHS roots cuttings in a glass of water in a bright spot from spring to late summer. Our monstera propagation guide covers every method step by step, and our monstera in water guide explains how long a cutting can stay in a jar.
