Soil Swiss cheese plants grow best in peat-based potting mix, which will help to trap moisture in the soil without causing it to become waterlogged. For strong growth, aim for a soil pH between 5.5 and 7. Water Water your Swiss cheese plant when the top inch of soil is dry. Soil should be be kept moist, but not soaked. A well-draining terracotta container will help to regulate moisture. Temperature and Humidity Swiss cheese plant thrives in high humidity (above 50%) and warm temperatures of 60°F to 85°F. A warm, well-lit bathroom (free of drafts) is a good spot for this plant. If you need to increase humidity, add a pebble tray or use a humidifier in its space. Fertilizer A balanced fertilizer made for houseplants with an N-P-K of 5-2-3 should be applied monthly during the growing season (May to September). However, wait until the plant is well established after potting it, as potting mix typically already has slow-release fertilizer in it, and the sensitive roots need time to settle after the stress of being moved. Staking and Support Swiss cheese plants are vigorous climbers, with aerial roots growing downward from the stem, which brace against the ground or any available support. In the wild, it will use these roots to push itself up onto an adjoining tree or woody vine. Providing stake support is crucial to keep it from escaping too far from its container: the most straightforward method is to insert a wooden, metal or plastic stake in the center of the pot.

Light: Monstera adansonii requires bright, indirect light to thrive, as direct sun can scorch its foliage. Limit direct sunlight exposure to mornings only.

Soil: Opt for a peat-based potting mix to retain moisture without waterlogging. Aim for a pH between 5.5 and 7 for optimal growth.

Water: Keep soil consistently moist but not waterlogged. Water when the top inch of soil is dry, and ensure good drainage with a terracotta pot.

Temperature and Humidity: Thrives in warm temperatures (60°F to 85°F) and high humidity (above 50%). Ideal for bathrooms, add humidity with a pebble tray or humidifier.

Fertilizer: Apply balanced fertilizer monthly during the growing season (May to September) with an N-P-K of 5-2-3. Wait for plant establishment after repotting.

Staking and Support: As a vigorous climber, Monstera adansonii requires stake support to prevent it from spreading too far. Insert a stake into the pot for stability.
