Monstera Obliqua Care Basics

Growing and caring for Monstera obliqua can be a rewarding experience, but it requires specific attention to its needs. Whether you are a seasoned plant enthusiast or a beginner looking to expand your collection, here are some essential care requirements to keep in mind:

Light

Monstera obliqua plants thrive in bright to medium indirect light, requiring at least 7 hours of light per day.
Avoid direct sunlight, as it can lead to leaf burn, and ensure the plant is not placed in low light conditions.
Consider using grow lights, especially if growing in a greenhouse cabinet or terrarium, to provide the optimal lighting conditions for your plant.

Soil

Use a well-draining potting mixture that is rich in nutrients and retains moisture well.
A mix of indoor potting soil, perlite, and sphagnum moss can help maintain the right balance of moisture and humidity for Monstera obliqua.
Loamy soil mixed with bark is another suitable option for this plant.

Water

Keep the soil evenly moist, allowing the top inch or two to dry out between waterings to prevent overwatering and root rot.
Check the soil moisture regularly and adjust your watering schedule accordingly, especially during the plant’s growing season.
Reduce watering in the fall and winter months when the plant enters dormancy.

Temperature and Humidity

Maintain a high humidity level of at least 80 percent and temperatures around 77 degrees Fahrenheit (25 degrees Celsius) to support optimal growth.
Consider using a humidifier or placing the plant in an enclosed environment like a greenhouse cabinet to create the ideal conditions.
Monitor temperature and humidity levels using small readers to ensure the plant’s well-being.

Fertilizer

Monstera obliqua is a slow-growing plant that requires less fertilizer than other Monsteraspecies.
Dilute a water-soluble liquid fertilizer to half strength and apply it once a month during the growing season.
Avoid fertilizing in the fall and winter months to support the plant’s natural growth cycle.
