Everything it needs
9 essentials at a glance
Watering
Philodendron mamei prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, using enough water to saturate the soil but ensuring excess drains out. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause leaf curling and browning tips.
Light
This plant thrives in bright, indirect light but can tolerate low 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. If the leaves start to lose their vibrant color, it may indicate insufficient light.
Soil
Philodendron mamei 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 recommended to ensure good drainage and aeration. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This plant enjoys high humidity levels of 60% or more.
To increase humidity, consider using a humidifier, placing a pebble tray with water under the pot, or misting the leaves regularly. Signs of low humidity include leaf browning and crisp edges.
Temperature
Philodendron mamei thrives in temperatures between 65-80°F (18-27°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 10-10-10 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, stunted growth, and poor leaf development.
Pruning
Prune Philodendron mamei in spring to maintain its shape and remove any dead or yellowing leaves.
Use clean, sharp scissors or pruning shears. You can also pinch back stems to encourage bushier growth. Deadheading is not necessary for this plant.
Repotting
Repot Philodendron mamei every 1-2 years or when it becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Gently remove the plant from its pot, loosen the roots, and place it in fresh soil. Water thoroughly after repotting.
Propagation
Philodendron mamei can be propagated 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 indirect light and keep the soil moist. Roots should develop in 2-4 weeks. The best time for propagation is during the growing season in spring or summer.
