Monstera Adansonii Care in Canada
Holed from its very first leaves, small enough for an apartment, and easier to propagate than almost anything else you own. One early decision shapes everything that follows.
Monstera adansonii — Swiss cheese vine, monkey mask — is the monstera that doesn’t make you wait. Where a deliciosa spends two or three years producing plain heart-shaped leaves before the holes arrive, adansonii is perforated from the start. It is also a fraction of the size, which for most Canadian apartments is the more important fact. What it asks in return is a decision you should make early, and an honest answer about light.
Monstera adansonii at a glance: Trail or climb — trailing keeps leaves small, climbing makes them bigger and more perforated. Pick one early. Water more often than a deliciosa: thinner leaves, smaller pot, dries faster. Bare leggy stems = not enough light. Move it brighter and cut it back. Propagation — any piece with a node, water, 3–6 weeks. Toxic to cats and dogs, and usually hanging within reach of one.
Trail It or Climb It — Decide Early
This is the one genuinely consequential choice with an adansonii, and it is rarely presented as a choice at all. Most are sold in hanging pots, so most people trail them by default and never learn there was another option.
| Trailing | Climbing | |
|---|---|---|
| Leaf size | Stays modest — the plant reads itself as hanging, not ascending | Increases leaf by leaf as the vine gains height |
| Fenestration | Present but light | More of it, and more pronounced on each new leaf |
| Look | Long curtains of small holed leaves | An upright column, closer to a small deliciosa |
| Space | Vertical drop, no floor space | A pole’s footprint |
| Cats | Hangs at exactly swiping height | Easier to keep out of reach |
Neither is wrong — the trailing look is the reason most people buy the plant. But if you bought it hoping the leaves would get bigger, trailing is working against you, and a pole is the fix. Decide early, because a vine trained one way for two years is awkward to convert.
Is your Monstera adansonii getting enough light this winter?
A Canadian winter cuts daylight roughly in half. See what your city actually gets this month, and whether a grow light is needed.
Bare, Leggy Stems — The Adansonii Problem
Long runs of naked stem with a tuft of leaves at the far end is the characteristic complaint about this plant, and it has one dominant cause: not enough light. A vine in dim conditions stretches toward a better spot, and the internodes — the gaps between one leaf and the next — lengthen as light falls. In a Canadian home this shows up between December and March, and by April you have a plant with a season’s worth of bare stem.
Two fixes, and they work together rather than as alternatives.
- Move it brighter. This stops new bare stem forming. It will not re-leaf the stem you already have — a node that has passed its moment does not sprout a leaf later.
- Cut it back. Pruning a leggy vine hard forces branching from nodes lower down, which is the only way to get a full plant again. Adansonii takes hard pruning far better than a deliciosa does — this is a vine, and cutting a vine is normal maintenance rather than an emergency.
The trick that turns the problem into the solution: every piece you cut off is a cutting, and every cutting can go back into the same pot. Three or four rooted pieces potted around the parent is how a sparse adansonii becomes a full one in a single season — which is a repair no deliciosa owner can make.
Watering a Thin-Leaved Vine
If you also own a deliciosa, do not water them on the same schedule. An adansonii has thinner leaves, a thinner stem and usually a much smaller pot, so it dries out considerably faster — and unlike its big relative, it tells you clearly, going limp and drooping within a day of running dry and recovering within hours of a drink.
Check the top 5–7 cm and water when it is dry. That still means stretching the interval through the winter, because the soil takes far longer to dry in low light — but adansonii is the one monstera where underwatering is a realistic failure mode rather than a theoretical one, particularly in a small hanging pot beside a heat vent.
One thing to check on a plant you have just bought: decorative hanging pots frequently have no drainage hole. An adansonii in a sealed pot will look fine for a couple of months and then yellow from the bottom up. If there is no hole, either drill one or keep the plastic nursery pot inside the decorative one and lift it out to water.
Useful here for the opposite reason to most plants. An adansonii in a small pot swings between wet and bone-dry much faster than a floor-standing monstera, and a hanging pot is awkward to finger-test. A probe gives you the root-zone reading in a second without taking the plant down. No batteries.

Propagation — The Easiest Monstera by Some Distance
The rule is the same as for every monstera: the cutting must include a node, the small knuckle on the stem where a leaf joins. What makes adansonii different is arithmetic. The vine is long and the nodes are close together, so a single leggy stem yields several cuttings rather than one, and the roots come quickly.
- Cut a section with one or two nodes and at least one leaf, about a centimetre below the lowest node.
- Stand it in water with the nodes submerged and the leaves out. Change the water weekly.
- Expect roots in 3–6 weeks — usually nearer the short end than a deliciosa takes.
- Pot several rooted cuttings together, or back into the parent pot, for a full plant rather than a single strand.
Season still applies. Spring through early autumn works; a cutting taken in January in Canada has neither the light nor the warmth to root, and usually rots instead. If you must prune a leggy plant mid-winter for appearance, do it — but expect the cuttings to be a write-off and treat any that take as a bonus.
“Is Mine Actually an Obliqua?”
It comes up constantly, because the two are genuinely confused in the trade — Kew’s Plants of the World Online records that the name Monstera obliqua is often misapplied to the more widespread Monstera adansonii. That is a fact about the name and about what gets sold, and it is the only part of this that is firmly settled. The morphological differences that circulate online are consistent between growers but are not a published key, which is a distinction worth keeping. Our obliqua page lays out the four marks people use and says how well documented each one is, without telling you what you own.
Canadian Winter, Briefly
Everything on the hub page applies, with two adansonii-specific notes. A hanging pot often sits higher in the room than a floor plant, which puts it closer to a ceiling heat vent and in drier air — worth checking, because crisp brown leaf edges in February usually trace back to that rather than to watering. And because this plant stretches toward light rather than simply slowing down, a dark winter costs you more here than it does on a deliciosa: the stem you grow between December and March is the bare stem you will be pruning in May.
Frequently Asked Questions
Should I let my Monstera adansonii trail or climb?
This single decision changes what the plant becomes, and there is no wrong answer — only a trade-off. Let it trail from a hanging pot and you get long curtains of small leaves, which is the look most people buy it for; the leaves stay modest and fenestration stays light. Give it a pole or trellis and the aerial roots grip, the plant shifts toward mature growth, and successive leaves get noticeably larger and more perforated. Decide early, because a plant trained one way is awkward to convert to the other.
Why is my Monstera adansonii bare and leggy?
Long stretches of bare stem with leaves only at the tips is the characteristic adansonii problem, and it is nearly always light. The plant keeps extending toward a brighter spot, and internodes — the gaps between leaves — get longer as light falls. It shows up worst from December to March in Canadian homes. Two fixes, used together: move it brighter, and prune. Cutting a leggy vine back hard forces branching from lower nodes, and each cut piece is a free cutting. Adansonii tolerates hard pruning far better than a deliciosa does.
How often should I water a Monstera adansonii?
More often than a deliciosa, and this catches people who own both. Adansonii has thinner leaves, a thinner stem and usually a smaller pot, so it dries out faster and sulks visibly when it goes too dry — limp, drooping stems that recover within hours of watering. Check the top 5–7 cm and water when dry. It is still possible to overwater it, especially in winter, but it is the one monstera where underwatering is a realistic failure mode rather than a theoretical one.
How do I propagate a Monstera adansonii?
It is the easiest monstera to propagate and close to the easiest houseplant of any kind. Cut a stem section with at least one node — the small knuckle where a leaf joins the stem — and stand it in water. Roots typically appear in 3–6 weeks, often at the fast end of that. Because the vine is long and node-rich, one leggy stem gives several cuttings, and potting three or four back into the parent pot is how you turn a sparse plant into a full one. Take cuttings spring through early autumn.
Is Monstera adansonii the same as Monstera obliqua?
No, and almost every plant sold as obliqua is in fact an adansonii — which is a statement about the trade, not about your plant. Kew's Plants of the World Online records that the name Monstera obliqua is often misapplied to the more widespread Monstera adansonii. Adansonii leaves are more substantial, with holes that are usually fully enclosed and a smaller proportion of the leaf area; obliqua is described as having leaves thin to the point of translucency with far more of the blade missing. If you want to work through it properly, our obliqua page sets out which marks to look at and how well documented each one is.
Why does my Monstera adansonii have yellow leaves?
In a Canadian home the first suspect is water sitting too long at the roots, especially between November and March when the soil takes twice as long to dry. Check that the pot drains and that you are not watering on a summer rhythm in winter light. Two adansonii-specific causes are worth ruling out too: a hanging pot with no drainage hole, which is common on decorative hangers, and a plant that has been left bone-dry repeatedly — chronic drought yellows the oldest leaves as the plant sheds them.
How big does a Monstera adansonii get?
The leaves stay modest — typically 10–25 cm long, considerably smaller than a deliciosa's — but the vine itself keeps going, and a happy plant will produce stems two to three metres long over a few years. That length is manageable in a way a deliciosa's bulk is not: you can coil it, train it along a wall, drape it from a shelf, or simply cut it back and replant the cuttings. It is the monstera for an apartment.
Is Monstera adansonii toxic to cats and dogs?
Yes, like every monstera — insoluble calcium oxalate crystals in the leaves and stems, causing immediate mouth and throat irritation when chewed. Adansonii deserves an extra note here: because it is usually grown trailing, it is often the monstera most within reach of a cat, hanging at exactly the height that invites a swipe. If you have a cat that chews plants, a wall-mounted pole or a high shelf with the growth trained upward is safer than a hanging basket.
