Expert tips
The key tip
Water when the top 2-3cm of soil is dry, not before—that's mistake number one. In winter, cut back drastically (once every 10-15 days). Wipe leaves every 15 days with a damp cloth to maintain photosynthetic uptake and remove dust that blocks respiration.
The common mistake
Gardeners water too regularly out of fear; Monstera dies far more often from root suffocation than thirst, especially in pots without proper drainage.
The pro's trick
Train the stems onto a moss pole or damp stick: this mimics natural tree support and triggers larger leaf formation with characteristic splits much faster than a plant trailing on its own.
Seasonal watch
Once heating kicks in during fall-winter, dry air yellows leaves and promotes spider mites: boost humidity with regular misting or set the pot on a bed of wet pebbles, especially December-February.
Care
Watering
Water regularly during the growing season (spring-summer) while keeping the substrate moist but not waterlogged. Reduce watering in fall-winter, letting the surface dry slightly between waterings. Use soft water if possible and ensure the pot drains well to prevent root rot.
Light exposure
Prefer bright indirect to moderate light: near a window without direct harsh sun is ideal. The plant tolerates partial shade but grows more slowly. Avoid prolonged dark spots that slow the formation of the characteristic leaf fenestrations.
Pruning and pinching
No drastic pruning is necessary. Pinch the tips to encourage branching and control height. Remove yellowed or damaged leaves, and aerial roots can be shortened or placed in the substrate to root them.
Fertilizer
Apply a balanced diluted fertilizer every 2 to 3 weeks during the growing season (April-September). In fall-winter, reduce or stop fertilizing. Always follow recommended dosages to prevent salt buildup.
Substrate and repotting
Use a rich, airy mix: universal potting soil with added perlite or pine bark. Repot every 1 to 2 years in spring if the plant outgrows its pot. A support or vertical structure (moss pole, trellis) aids natural vine-like growth.
Pests and diseases
Watch for mealybugs, spider mites, and aphids, especially in dry air. Clean leaves regularly with a damp cloth. Root rot and fungal spots appear with stagnant excess moisture: prioritize good air circulation and flawless drainage.
Did you know?
Monstera deliciosa owes its name to the monstrous appearance of its large perforated leaves, but it also goes by 'Fruit of Switzerland' or 'Monkey's Bread' depending on the region. In reality, its edible fruit (rarely obtained indoors) resembles a giant cream-white corn cob: tradition holds that the Aztecs considered it a gift from the gods. Its leaf fenestrations fascinate botanists: they are thought to have evolved to reduce wind resistance and optimize photosynthesis in dense forest environments.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
