Why doesn't my Monstera have holes or splits?

Fenestrations come with maturity and light. Young plants make solid heart-shaped leaves; the splits appear as the plant ages and climbs. Give it bright indirect light and a moss pole to climb, and each new leaf will be larger and more divided than the last.

How often should I water a Monstera deliciosa?

Water when the top 2–5 cm of soil is dry — usually about once a week in summer and every 10–14 days in winter. It would rather dry out a little than sit wet, so always let the surface dry before watering again.

Should I let my Monstera climb or trail?

Climbing. In the wild it scrambles up trees, and a moss pole or trellis encourages bigger leaves with more fenestration. Left to trail, leaves tend to stay smaller and less split.

Monstera deliciosa care: light, water, and how to get fenestrations

Published June 4, 2026

The Monstera deliciosa — the Swiss cheese plant — is the houseplant everyone recognises and almost no one waters correctly. It is genuinely easygoing, but it carries one source of quiet disappointment: the leaves that should be slashed and holed come in plain and solid. That is not bad luck. It is a plant telling you it wants two specific things.

What it is

A climbing aroid from the rainforests of southern Mexico and Central America. In the wild it germinates on the forest floor and hauls itself up tree trunks toward the light, getting larger and more fenestrated the higher it climbs. That instinct — climb toward light — is the key to the whole plant.

Light

Bright, indirect light. It will survive in medium light, but that is exactly when leaves stay small and undivided. A spot near an east or north window, or a few feet back from a south/west one, is ideal. A little gentle morning sun is fine; harsh midday sun through glass will scorch.

Water

Let the top 2–5 cm of soil dry out between waterings — roughly weekly in the growing season, every 10–14 days in winter. Then water thoroughly until it runs from the drainage holes, and tip away anything left in the saucer. The most common Monstera mistake is kindness: watering little and often keeps the roots wet and rots them. When in doubt, wait.

The two things that trigger fenestration

Maturity. Juvenile leaves are solid hearts. The holes and splits develop as the plant ages — you cannot rush a young plant into fenestrating.
Light + something to climb. Give it bright light and a moss pole or trellis, and each new leaf emerges larger and more divided. A Monstera that climbs fenestrates; a Monstera that sprawls across the floor usually does not.

Those thick aerial roots reaching into the air are normal and useful — guide them onto the moss pole or back into the pot; don’t cut them off.

Soil and feeding

Use a chunky, free-draining aroid mix — houseplant compost with added bark, perlite, and a little charcoal. The roots want air. Feed with a balanced liquid fertiliser monthly through spring and summer, and ease off in winter. Repot every couple of years when roots circle the pot or push out the bottom.

Common problems

Yellowing leaves: usually overwatering. Check that the soil is drying between waterings and that the pot drains.
Brown, crispy edges: under-watering or very dry air. Water more consistently; it is forgiving but not immortal.
Leggy growth, small leaves: not enough light. Move it brighter and give it support to climb.
Weeping droplets from leaf tips: harmless guttation, often after a heavy watering.

The honest summary

A Monstera wants bright indirect light, a soak-then-dry watering rhythm, and a pole to climb. Get those three right and it becomes one of the fastest, most rewarding plants you can grow.

The watering rhythm is the part that trips people up — too often, not too rarely. LeafPal tracks the dry-down for you and reminds you when the top of the pot has actually dried, instead of nagging on a fixed day.
