Everything it needs
9 essentials at a glance
Watering
Monstera epipremnoides prefers to be watered when the top 1-2 inches of soil feel dry to the touch.
During the growing season (spring and summer), water approximately once a week, ensuring the pot drains well. In fall and winter, reduce watering to every 10-14 days. Signs of over-watering include yellowing leaves and root rot, while under-watering can lead to wilting and browning leaf tips.
Light
This plant thrives in bright, indirect light but can tolerate lower light conditions.
Ideally, place it near a window with filtered sunlight for 6-8 hours a day. Avoid direct sunlight, as it can scorch the leaves. Monstera epipremnoides can adapt to partial shade but may grow slower in such conditions.
Soil
A well-draining potting mix is essential, ideally a blend of peat, perlite, and orchid bark.
The pH range should be between 5.5 and 7.0. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.
Humidity
Monstera epipremnoides prefers humidity levels of 60% or higher.
To increase humidity, consider using a humidifier, placing a pebble tray with water beneath the pot, or misting the leaves regularly. Signs of low humidity include browning leaf edges and curling leaves.
Temperature
The ideal temperature range for Monstera epipremnoides is between 65-85°F (18-29°C).
It is not frost-tolerant and should be kept above 50°F (10°C). This plant thrives in USDA hardiness zones 10-12, and it can suffer in extreme heat or cold.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter when the plant's growth slows. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor leaf development.
Pruning
Prune Monstera epipremnoides in spring to maintain its shape and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. You can also pinch back growth to encourage bushier growth. Deadheading is not necessary for this plant.
Repotting
Repot Monstera epipremnoides every 1-2 years or when it becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes or stunted growth. To repot, gently remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Monstera epipremnoides can be propagated through stem cuttings.
Take a cutting with at least one node and aerial root, place it in water or moist soil, and keep it in a warm, bright location. Change the water every few days if propagating in water. The best time to propagate is during the growing season (spring and summer).

Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow actively. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives adequate light and humidity. Water regularly, allowing the top soil to dry out between waterings.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize until late fall, then stop for the winter.
Winter
In winter, keep the plant in a warm location, away from drafts. Water less frequently and monitor humidity levels to prevent stress.
Toxicity & Safety
Monstera epipremnoides is toxic to pets and humans if ingested. The leaves contain calcium oxalate crystals, which can cause irritation, swelling, and difficulty swallowing. Symptoms of ingestion include mouth and throat irritation, vomiting, and difficulty breathing.
