Everything it needs
9 essentials at a glance
Watering
Monstera dubia prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf curling and browning edges.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Ideally, place it near a window with filtered sunlight for about 6-8 hours daily. Direct sunlight can scorch the leaves, while too little light may stunt growth.
Soil
Monstera dubia prefers a well-draining potting mix with a pH range of 5.5 to 7.0.
A blend of peat, perlite, and orchid bark works well to ensure proper drainage and aeration. Avoid heavy soils that retain too much moisture.
Humidity
This plant enjoys high humidity levels, ideally between 60-80%.
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 stress include browning leaf tips and edges.
Temperature
Monstera dubia thrives in temperatures between 65-85°F (18-29°C) and is best suited for USDA hardiness zones 10-12.
It can tolerate brief periods of cooler temperatures but should be protected from frost and extreme heat.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or similar during the growing season, every 4-6 weeks.
In fall and winter, reduce fertilization to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Monstera dubia in spring to encourage bushier growth and remove any dead or yellowing leaves.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but removing damaged leaves can improve overall plant health.
Repotting
Repot Monstera dubia 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 and slowed growth. When repotting, gently loosen the roots and place the plant in fresh potting mix.
Propagation
Propagation can be done through stem cuttings.
Take a cutting with at least one node and a few leaves, and place it in water or moist soil. Ensure it receives indirect light and keep the soil consistently moist. The best time to propagate is during the growing season, from spring to early summer.

Care through the year
Spring
In spring, increase watering frequency as the plant enters its growing season. Fertilize every 4-6 weeks and monitor for new growth.
Summer
During summer, ensure the plant receives bright, indirect light and maintain high humidity levels. Water regularly, allowing the top inch of soil to dry out between waterings.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue fertilizing every 6-8 weeks until late fall, and prepare for cooler temperatures.
Winter
In winter, water less frequently, about every 2-3 weeks. Keep the plant in a warm location away from drafts and provide adequate light.
Toxicity & Safety
Monstera dubia is toxic to pets (cats and dogs) and humans if ingested. The leaves contain calcium oxalate crystals, which can cause irritation, swelling, and digestive issues. Symptoms of ingestion include mouth and throat irritation, vomiting, and difficulty swallowing.
