Shingle monstera (Monstera acuminata) care

Aroids · needs attention to keep

Last updated 26 October 2026

Shingle monstera (Monstera acuminata) wants bright indirect light; an hour or two of early sun is fine, midday sun is not. Water it weekly. Water when the top 5 cm of mix is dry, then water until it runs out of the bottom. Monsteras would rather be a day late than a day early. Pot it in a chunky aroid mix — bark, perlite and coir, something water runs straight through. A balanced liquid feed at half strength, every second or third watering in spring and summer, and repot once a year. Humidity: above 60%; the shingles brown at the edges in dry air. Toxic to cats, dogs and people if chewed — the sap carries insoluble calcium oxalate crystals, which burn the mouth and throat.

A shingling monstera from Mexico and Central America: young plants press glossy, pointed heart-shaped leaves flat against a board or trunk as they climb. Given height, the adult leaves stand away from the support and develop holes. Most people keep it shingling on a slab of bark.

Watering a Shingle monstera

Water weekly. Water when the top 5 cm of mix is dry, then water until it runs out of the bottom. Monsteras would rather be a day late than a day early.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light, which in practice means a metre or two back from an east or west window, or right up against a north one. Monsteras will survive in low light and simply stop earning their name: the new leaves come out smaller and solid, with no splits. Direct midday sun bleaches them to a pale khaki.

Humidity and temperature

Above 60%; the shingles brown at the edges in dry air. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Monsteras are climbers that root into bark in the wild, not into soil. A peat-only compost holds water against the roots and is the usual reason a healthy plant turns yellow. Cut potting soil half-and-half with orchid bark and perlite, or buy a ready-made aroid mix.

Feeding

A balanced liquid feed at half strength, every second or third watering in spring and summer. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot once a year. Every second spring. Give it a flat board or a slab of bark rather than a round pole — the leaves need a flat surface to shingle against.

Common problems

Yellow leaves, usually the oldest ones first
Overwatering, or a mix that holds water. The roots have been wet long enough to start dying back.

Fix: Let it dry out further between waterings, and repot into something chunkier if the mix stays soggy for days.

Yellow leaves: how to read it on any plant
New leaves come out small and with no splits
Not enough light, or nothing to climb.

Fix: Move it closer to the window and give it a moss pole. Fenestration is a maturity signal; the plant withholds it when conditions say stay small.
Brown crispy edges
Dry air, or a build-up of salts from tap water and fertiliser.

Fix: Raise humidity, and flush the pot thoroughly with plain water every few months.

Brown tips and edges: how to read it on any plant
Fine webbing between stems, leaves stippled pale
Spider mites, which arrive in dry warm air.

Fix: Shower the whole plant, then treat every five days for three weeks — one treatment never gets the eggs.

Propagation

Cut just below a node — the brown bump where a leaf and an aerial root meet. A cutting with a node and one leaf roots in water in three to six weeks, or straight into damp sphagnum. A cutting without a node will never root, however long you wait.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

The ASPCA does not list Monstera acuminata itself, but lists a relative, Ceriman (Monstera deliciosa), as toxic to cats and dogs (checked 26 October 2026).

If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.

This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.

Questions people ask

How often should you water a Shingle monstera?

Water weekly as a starting point — that is the cadence PlantParlour sets for Monstera acuminata. Water when the top 5 cm of mix is dry, then water until it runs out of the bottom. Monsteras would rather be a day late than a day early. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.

How much light does a Shingle monstera need?

Is Shingle monstera toxic to cats and dogs?

Toxic to cats, dogs and people if chewed — the sap carries insoluble calcium oxalate crystals, which burn the mouth and throat. Keep it off the floor if anything in the house tastes its way through life. The ASPCA does not list Monstera acuminata itself, but lists a relative, Ceriman (Monstera deliciosa), as toxic to cats and dogs (checked 26 October 2026). If a pet has eaten part of a plant, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 straight away.
