Monstera Deliciosa
Monstera deliciosa · also called Swiss cheese plant, split-leaf philodendron
Monstera deliciosa is an easy, fast-growing tropical with iconic split leaves. Give it bright indirect light and water when the top 2 inches of soil dry out.
The Monstera deliciosa is one of the most popular houseplants in the world, prized for its large, glossy leaves that develop dramatic splits and holes (called fenestrations) as the plant matures. In the wild it's a climbing vine that scrambles up tree trunks toward the canopy, which is why it appreciates a moss pole or trellis indoors.
Monsteras are forgiving and vigorous, making them a great choice for beginners who want a big, sculptural plant. With bright indirect light and a consistent watering rhythm, a young plant can grow several feet in a single season. The more light it gets (without direct midday sun), the larger and more fenestrated its leaves become.
How to care for Monstera Deliciosa
Light
Bright, indirect light is ideal — an east or north window, or a few feet back from a brighter one. It tolerates medium light but grows slowly and stays unfenestrated. Avoid harsh direct sun, which scorches the leaves.
Watering
Water thoroughly when the top 2 inches (5 cm) of soil feel dry, usually every 1–2 weeks. Let excess drain fully and never leave the pot sitting in water. Reduce frequency in winter when growth slows.
Humidity
Average household humidity is fine, but it thrives at 50–60%. Higher humidity encourages larger leaves and more fenestration. Group with other plants or use a humidifier in dry rooms.
Temperature
Comfortable at 65–85°F (18–29°C). Protect it from cold drafts and keep it above 55°F (13°C); it is not frost tolerant.
Soil & potting mix
A chunky, well-draining aroid mix — potting soil amended with orchid bark, perlite and a little coco coir. Good aeration prevents root rot.
Feeding
Feed monthly during spring and summer with a balanced liquid fertilizer at half strength. Stop feeding in late autumn and winter.
Pruning & grooming
Prune to control size or remove damaged leaves; cut just above a node with clean shears. Wipe the leaves occasionally to remove dust and keep them photosynthesizing efficiently.
Repotting
Repot every 1–2 years in spring, moving up one pot size when roots circle the bottom. Add a moss pole to support climbing and encourage bigger leaves.
Propagation
Easy from stem cuttings. Cut below a node that includes an aerial root, then root in water or moist sphagnum moss before potting up.
Common Monstera Deliciosa problems
- Yellow leaves. Usually overwatering — let the soil dry further between waterings and check that the pot drains.
- No splits in the leaves. Young plants and low light produce solid leaves. Move it brighter and be patient as it matures.
- Brown, crispy edges. Low humidity or underwatering. Raise humidity and keep the watering rhythm consistent.
Monstera Deliciosa FAQ
Why isn't my monstera splitting?
Fenestrations develop with maturity and adequate light. Young monsteras naturally have solid leaves, and plants in low light stay unsplit. Give it bright indirect light, a moss pole to climb, and time — new leaves will gradually show more splits and holes.
How often should I water a monstera?
Water when the top 2 inches of soil are dry, which is typically every 1–2 weeks depending on light, pot size and season. It's better to underwater slightly than to keep the soil soggy, since monsteras are prone to root rot.
Are monsteras toxic to cats and dogs?
Yes. Monstera leaves contain calcium oxalate crystals that irritate the mouth and digestive tract if chewed, causing drooling, pawing at the mouth and vomiting. Keep the plant out of reach of pets.
