How often to water a monstera
Water a monstera every 1–2 weeks, when the top inch or two of soil has dried out. Like most tropicals it wants a real drink — water until it runs from the drainage holes — and then a dry-down period before the next one. Soggy, never-quite-dry soil is what kills them.
The interval drifts with the seasons: closer to weekly in bright, warm summer months, closer to every two weeks in winter. Let the soil, not the date, make the call.
Light and humidity
Bright, indirect light is non-negotiable if you want the famous holes. Those splits — “fenestrations” — only develop when a monstera gets enough light and matures; a plant in a dim corner stays small with plain, solid, heart-shaped leaves and people wonder what they did wrong. The answer is almost always: more light.
Keep it out of harsh direct sun through glass, which scorches the leaves. A few feet back from a bright window, or beside an east-facing one, is ideal.
Humidity: Likes higher humidity but copes with average rooms.
Why is my monstera dying?
Yellow leaves usually mean overwatering — the same story as most houseplants. Check that the soil is drying between waterings and that the pot actually drains.
Brown, crispy edges point to dry air or letting it get too thirsty. Monsteras like a bit more humidity than the average living room; a grouping of plants or the occasional misting helps, though it’s not essential.
No splits on new leaves? That’s not a disease — it’s a light problem. A young monstera also simply isn’t old enough yet. Give it brighter light and time, and the new leaves come in with windows.
How to propagate a monstera
Propagate a monstera from a stem cutting that includes a node, ideally one with an aerial root already growing from it. A leaf with only its stalk and no node can root, but it will never grow a new plant. Cut just below the node, keep one or two leaves, and root it in water or damp sphagnum moss.
Expect roots in about two to six weeks, faster in a warm, bright spot. Pot it into a chunky, free-draining mix once the roots are a few inches long, and give it a moss pole early if you want large, split leaves later.

Keeping it alive when you share a home
A monstera is a big, visible, second-living-room-member kind of plant — which is exactly why its care slips through the cracks in a shared home. It’s too established to look thirsty quickly, so “it seems fine” becomes everyone’s reason not to water it, right up until it isn’t fine.
For a plant this slow to complain, the move is a shared schedule rather than vibes. Decide who checks the soil and when, so the monstera isn’t quietly relying on four people each assuming one of the others did it. (A plant this expensive is worth a reminder neither of you can ignore.)
If you use Family Greenhouse for this, sharing plants with a household explains who sees what and who gets reminded.
The honest bit
Unpopular opinion: most “my monstera won’t fenestrate” problems are light problems wearing a costume. People reach for humidifiers and fertilizer and moss poles when the plant just needs to be a meter closer to the window. Fix light first; fix everything else second.
And the moss pole is genuinely worth it once the plant is a year or two in — monsteras are climbers, and a supported, climbing monstera produces bigger, holier leaves than one flopping over the side of its pot. That part of the hype is real.
Monstera FAQ
- How often should I water a monstera?
- Every 1–2 weeks, when the top 1–2 inches of soil are dry. Lean weekly in bright summer months and every two weeks in winter. Always let it drain — it hates sitting in water.
- Why doesn’t my monstera have holes in its leaves?
- Almost always not enough light, or the plant is still young. The famous splits (fenestrations) develop as a monstera matures in bright, indirect light. Move it brighter and give it time.
- Why are my monstera’s leaves turning yellow?
- Usually overwatering. Let the top inch or two of soil dry between waterings and confirm the pot drains. Brown crispy edges, by contrast, mean dry air or underwatering.
- Is a monstera toxic to cats and dogs?
- Yes. The ASPCA lists Swiss Cheese Plant (Monstera deliciosa) as toxic to cats and dogs. Same calcium oxalate crystals as pothos — chewing irritates the mouth and stomach. Mild for a nibble, but worth keeping out of reach of a cat that likes to taste-test.
