Swiss Cheese Plant Care – How to Grow a Holey Monstera

The Swiss cheese plant earns its name from the dramatic holes and splits that develop across its glossy, oversized leaves. Whether you have a Monstera deliciosa with its deep, edge-reaching slits or a Monstera adansonii dotted with neat oval windows, this tropical vine is one of the most forgiving statement houseplants you can grow. It tolerates a beginner’s mistakes, climbs happily up a moss pole, and rewards good light with the fenestrated foliage everyone wants. Here is everything you need to keep a Swiss cheese plant thriving indoors, plus how to coax out those signature holes and troubleshoot the problems that crop up most.

Swiss Cheese Plant at a Glance

Both species sold as “Swiss cheese plant” belong to the genus Monstera, part of the arum family (Araceae), and both come from the rainforests of southern Mexico and Central America. In the wild they are climbing vines that scramble up tree trunks using aerial roots, reaching for the brighter light near the canopy.

The name itself is a clue to the plant’s character. Monstera refers to its monstrous size, and deliciosa to the edible, pineapple-banana-flavored fruit it produces in the wild but almost never indoors.

Is Your Swiss Cheese Plant a Deliciosa or an Adansonii?

This is the single most confusing thing about owning a Swiss cheese plant, because two different species share the nickname and they are not interchangeable. Sorting out which one you have makes every other care decision easier.

Monstera deliciosa is the large, architectural plant most people picture. Its leaves start out solid and heart-shaped, then develop deep splits that cut all the way to the leaf edge as the plant matures, eventually growing more than 3 ft (1 m) wide on a big specimen. It wants to climb and gets genuinely large.

Monstera adansonii is the smaller, daintier cousin. Its leaves are narrower and more elongated, with a thinner, more papery feel, and they are perforated with completely enclosed oval holes that almost never split open to the margin. It develops those holes far younger, often within its first few leaves, and it looks fantastic trailing from a hanging pot as well as climbing a pole.

The quickest test: if the holes are sealed windows inside the leaf, you have adansonii; if the splits run out to the edge, you have deliciosa. Both are cared for the same way in the basics of light, water, and feeding, so do not panic if you are unsure, but knowing the species sets the right expectations for size and leaf shape.

A small word of warning when buying. Young plants of both species look almost identical to a generic philodendron, and small deliciosa plants are still sometimes mislabeled as “split-leaf philodendron” or Philodendron pertusum. They are not philodendrons at all.

Light Requirements

Light is the factor that matters most, both for keeping the plant healthy and for getting those holes. In the rainforest, Monstera grows under the tree canopy, so it is adapted to bright but filtered light rather than harsh, direct sun.

Indoors, aim for bright, indirect light. A spot a few feet back from a sunny window, or right beside an east- or west-facing window that gets gentle morning or evening sun, is close to ideal. If a window delivers strong midday sun, filter it through a sheer curtain, because more than a couple of hours of direct summer sun will scorch and bleach the fenestrated leaves.

Swiss cheese plants are remarkably tolerant of lower light and will survive several feet from a window, but the trade-offs are real: growth slows, the plant stretches, and crucially, new leaves come in solid with few or no holes. So while it can live in a dim corner, it will not look its best there.

One quirk worth knowing is that, as seedlings, Monstera deliciosa actually grows toward darkness rather than light. In the wild this sends the young vine toward the dark base of a tree trunk, which it then climbs to reach the brighter canopy. Indoors that instinct can send new shoots creeping into dim corners, so if you see stems wandering the wrong way, guide them back or move the plant to better light.

How to Water a Swiss Cheese Plant

Watering is where most people go wrong, and the good news is that Monstera is forgiving as long as you get the rhythm right. Water thoroughly, then wait.

Pour lukewarm water evenly over the soil until it runs freely from the drainage holes, which also flushes out any built-up fertilizer salts. Then let the top few inches of soil dry out before you water again. Stick a finger in: if the soil still feels wet, leave it a few more days. Depending on your light, warmth, and humidity, that usually works out to roughly once a week in the growing season and less often in winter.

The key insight is that it is the frequency of watering, not the amount per session, that causes root rot. A thorough soak with good drainage is fine; what kills these plants is keeping the soil constantly soggy. When in doubt, underwater rather than overwater. Cut back noticeably in fall and winter, when growth slows and the plant uses far less water.

Lukewarm water is better than cold, which can chill the roots and slow growth. Tap water is generally fine if you would drink it yourself, but in hard-water areas or if you notice leaf blemishes from mineral buildup, switch to filtered or distilled water.

Soil and Potting Mix

Monstera needs a soil that holds some moisture but drains fast and stays airy around the roots, since it will not tolerate standing water. A generic peat-free houseplant mix works, but a chunky aroid blend is better. Look for a mix that includes bark or orchid bark, perlite, and worm castings or coco coir, all of which improve aeration and drainage.

Whatever you use, the pot must have drainage holes. Plastic pots are a good practical choice because terracotta and ceramic can stay cold and damp when wet, which slows the plant in cooler rooms.

Temperature and Humidity

As a tropical native, the Swiss cheese plant likes warmth. It grows best between 65 and 85 F (18-29 C), and you should never let it drop below 55 F (13 C); below about 54 F, cold damage shows up as blackening leaves. It cannot survive frost, so keep that in mind before moving it outdoors for the summer. Cooler nights down to around 55 to 65 F (13-18 C) in winter are fine and even welcome as a rest period.

Humidity is helpful but not as fussy a requirement as some care guides imply. The plant takes average household humidity in stride and grows perfectly well without daily misting. That said, it is happiest with moderate to high humidity, around 50 to 60 percent, and very dry air, such as next to a running radiator or air conditioner, will cause crispy brown leaf tips. If your home runs dry, a pebble tray or a humidifier raises humidity more reliably than misting does. Keep the plant at least a few feet from heat sources to avoid drying it out.

Feeding Your Monstera

Feeding keeps new leaves coming in big and glossy. Use a balanced houseplant fertilizer at the strength on the label, applied every couple of weeks to once a month during the active growing season from spring into early fall. Stop feeding in late fall and winter, when the plant is resting, because fertilizer applied to a dormant plant builds up as salts and causes leaf burn rather than growth.

A useful trick: if your Monstera is growing faster than you want, feed it less and keep it in a snug pot to slow it down. If it has stalled and looks hungry, feed more regularly and give it room to grow.

Support, Staking, and Pruning

Left to its own devices, a Swiss cheese plant will sprawl sideways across the floor toward the nearest light, which becomes both a mess and a trip hazard. Give it something to climb. A moss pole is the classic choice because the aerial roots grip into it, but a sturdy coir pole, bamboo cane, or trellis works too.

Climbing support does more than tidy the plant up. The aerial roots need something to grip before the plant will commit to producing its largest, most heavily fenestrated leaves, so a moss pole genuinely encourages better foliage. Add the support when you repot, loosely tie the stems to it with soft string, and mist a moss pole occasionally to encourage the roots to root into it.

For pruning, use clean, sharp scissors or secateurs. Trim off any fully yellowed or browned leaves close to the main stem, and cut back leggy or overgrown stems to control size and shape; the plant will push out replacement growth. Spring is the best time, though you can prune lightly any time of year. To rejuvenate a top-heavy plant with a bare base, cut it back by about a third, and consider rooting the cuttings back into the same pot to fill it out.

Those thick aerial roots are normal and healthy. You have three options: leave them, tuck the longer ones down into the soil or into a moss pole, or trim them off if you dislike the look. Tucking them in is best for the plant, but Monstera is tough enough that removing tidy-up roots does no lasting harm.

How to Repot a Swiss Cheese Plant

Repot a young plant soon after you bring it home, then every one to two years for small plants and every two to three years once it is in a large container. A reliable sign it is ready is when several roots start poking out of the drainage holes. Choose a pot only an inch or two (a few cm) wider than the current one, always with drainage, and use fresh aroid or houseplant mix. Spring is the ideal season.

Be aware that potting up into a much bigger container will produce a much bigger plant, so size up modestly if you want to keep the plant in check.

Repotting is also your chance to inspect the roots and add a moss pole. Water the plant a few hours beforehand to reduce transplant shock, ease it out of its pot, and gently check the rootball. Healthy roots are cream-colored and plump; trim away any that are brown, mushy, or flat with clean scissors. Settle the plant into fresh mix, firm it in gently, and water it the next day. Do not feed for the first couple of months, since fresh mix already contains nutrients.

If the plant wilts or its leaves curl a few days after repotting, the roots were probably disturbed too much. Keep it warm and brightly but indirectly lit, hold off watering until the top of the soil dries, and it should recover within a few weeks.

How to Propagate a Swiss Cheese Plant

Monstera is one of the easiest houseplants to propagate, and stem cuttings are the simplest route. The non-negotiable rule is that every cutting must include at least one node, the small bump on the stem where a leaf or aerial root emerges. A piece without a node will never root.

To take a cutting, choose a healthy stem with at least one node and a leaf or two, and cut cleanly just below the node.

To root in water, sit the cutting in a glass with the node submerged but the leaves above the waterline, place it in bright indirect light, and change the water every few days. Roots usually appear within two to three weeks; once the longest is around 2 to 4 inches (5-10 cm), pot it up into well-draining mix.

To root directly in soil, plant the node in a small pot of moist, well-draining mix, keep it warm and in bright indirect light, and keep the top of the soil from drying out completely while it roots. You can dip the cut end in rooting hormone first, but it is not necessary.

For larger plants, air layering is the most reliable method and lets you grow roots before you cut. Wrap damp sphagnum moss around a node with an aerial root, hold it in place by enclosing it in a clear plastic bag tied at both ends with a few small air vents, and keep the moss moist. Once roots develop inside the bag over the following weeks to months, cut the rooted section off and pot it up.

Why Swiss Cheese Plants Have Holes

Those holes have a proper name, fenestration, and they are not unique to Monstera. Over the years people have suggested the holes let hurricane winds and heavy rain pass through without tearing the leaves, or that they channel water down to the roots. Both ideas have weaknesses: if storm resistance were the point, most rainforest plants would have evolved the same trait, and a plant in a daily-rain habitat hardly needs help getting water to its roots.

The leading explanation, proposed by botanist Christopher Muir, is about light. On the dim rainforest floor, understory plants survive by catching sunflecks, brief patches of sunlight that filter through the canopy. By spreading the same amount of leaf tissue over a larger area, a fenestrated leaf increases its odds of intercepting those scattered sunflecks. A solid leaf and a holey leaf capture the same light in steady bright conditions, but in dappled understory light the fenestrated leaf comes out ahead, and that advantage matters most once a plant is growing fast and needs all the light it can get.

What to Do When Your Swiss Cheese Plant Has No Holes

A holeless Monstera is the most common disappointment, and it almost always comes down to one of a few fixable causes.

Most often the plant is simply too young. Monstera leaves start out solid and only begin to fenestrate as the plant matures, typically once it reaches around 3 ft (1 m) tall, so a small plant with whole leaves is perfectly normal and just needs time.

If a plant is mature and still producing solid leaves, look first at light. Insufficient light is the usual culprit; even large specimens grown in dim conditions will skip fenestration entirely. Move the plant to brighter, indirect light, near a south- or east-facing window if you can.

The next thing to add is climbing support. A moss pole gives the aerial roots something to grip, which encourages the plant to mature and produce its larger, fenestrated leaves. Finally, rule out underfeeding and a cramped, rootbound pot, both of which can hold a plant back; feed regularly in the growing season and repot if roots are circling the pot. Trimming off some of the older, smaller leaves near the base can also nudge the plant to invest in bigger, holey new growth.

Common Problems and How to Fix Them

Swiss cheese plants are generally pest- and disease-free, and most problems trace back to watering, light, or temperature. The trick is reading the symptom correctly.

Yellowing leaves are the most common complaint and usually point to watering, with overwatering and the resulting early root rot at the top of the list; let the soil dry out more between waterings. An occasional yellow lower leaf on a growing plant is just natural aging and nothing to worry about. Other causes include cold exposure, a rootbound pot starving the plant of nutrients, underfeeding, and pests. If yellowing spreads steadily and the plant has stalled, check the roots.

Brown leaf edges and crispy tips generally mean the air is too dry or the plant is underwatered; raise humidity and check your watering rhythm. Random faded or brown patches, especially with a crispy texture, usually mean sun scorch from too much direct light, so move the plant out of harsh sun. Brown tips paired with a yellow margin often signal fertilizer salt buildup, in which case flush the soil and ease off feeding.

Black, soft, mushy leaves are a serious sign of root rot from chronic overwatering, or of cold damage below 55 F (13 C). Remove affected leaves, move the plant somewhere warm, and let the soil dry out. If the stem itself turns brown and mushy, take healthy stem cuttings to save the plant and discard the rotten rootball.

Curling leaves typically mean the plant is thirsty and is curling inward to reduce water loss; water it and the leaves should relax.

Leggy growth with long gaps between leaves comes from too little light. Move the plant closer to a window and give it a support to climb.

Pests are uncommon but possible. Thrips are the ones to watch, since even a small population can damage a Monstera quickly; they are hard to spot but cause discoloration and stippling as they drain the leaves. Mealybugs show up as white, cottony clusters in leaf crevices, and spider mites and scale can appear too. Fungus gnats are harmless to the plant but signal soil that stays too wet. Wipe pests off with a damp, soapy cloth and treat with insecticidal soap or neem oil, repeating as needed; cleaning the leaves regularly with a soft cloth helps you catch infestations early.

One harmless oddity is guttation, the water droplets that collect at leaf tips after a thorough watering. It is not a problem, just a sign there is plenty of moisture at the roots, and easing off the watering reduces it.

Is the Swiss Cheese Plant Toxic?

Yes. All parts of the Swiss cheese plant are toxic to people, cats, and dogs because the sap contains calcium oxalate crystals. Chewing or eating the leaves can cause oral irritation, a burning or sore mouth, drooling, vomiting, and difficulty swallowing.

The reassuring part is that the calcium oxalates mainly exist to make the plant taste unpleasant, so most reactions are superficial rather than dangerous. Still, keep the plant out of reach of curious pets and small children, and wear gloves if you have sensitive skin when pruning or propagating, since the sap can irritate skin.

Monstera Varieties Worth Knowing

Beyond the standard all-green deliciosa and the trailing adansonii, a handful of cultivars are widely available. Monstera deliciosa ‘Variegata’, often sold as ‘Albo’, has striking cream-and-green leaves but is slower-growing, trickier to keep variegated, and pricier. ‘Thai Constellation’ is a reliably variegated cultivar speckled with creamy white, once rare and now far easier to find. ‘Borsigiana’ is a slightly more compact form with smaller leaves, useful if space is tight, and ‘Mint’ is a sought-after variety usually sold online as cuttings. Variegated types need bright light and regular feeding to hold their coloring and grow more slowly overall.

The Swiss cheese plant rewards a little understanding with years of bold, sculptural foliage. Get the light right, water on a dry-then-soak rhythm, give it a moss pole to climb, and your Monstera will reward you with the dramatic, hole-filled leaves that made it a houseplant icon.
