Everything it needs
9 essentials at a glance
Watering
Monstera Adansonii prefers to be watered when the top 1-2 inches of soil are 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 2-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf edges.
Light
This plant thrives in bright, indirect light but can tolerate lower light conditions.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight, as it can scorch the leaves. If placed in lower light, growth may slow down, and the plant may become leggy.
Soil
Monstera Adansonii prefers a well-draining potting mix with a pH range of 5.5 to 7.0.
A mix of peat, perlite, and orchid bark is ideal for providing aeration and moisture retention. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This plant enjoys high humidity levels of 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 Adansonii thrives in temperatures between 65-85°F (18-29°C).
It is best suited for USDA hardiness zones 10-12. Protect the plant from temperatures below 50°F (10°C) and avoid placing it near drafts or heating vents.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or a diluted fertilizer every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor leaf development.
Pruning
Prune Monstera Adansonii in spring to maintain its shape and encourage bushier growth.
Use clean, sharp scissors or pruning shears to remove any dead or damaged leaves. Deadheading is not necessary, but removing yellow leaves can improve the plant's appearance.
Repotting
Repot every 1-2 years or when the plant 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 the roots, and place it 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 the cutting receives bright, indirect light. Roots should develop within 2-4 weeks. The best time for propagation is in spring or early summer.

Summer
During summer, maintain consistent watering and humidity levels. Ensure the plant receives bright, indirect light for optimal growth.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Continue to fertilize until late fall, then stop until spring.
Winter
In winter, water less frequently and keep the plant in a warm location away from drafts. Monitor humidity levels to prevent stress.
