Everything it needs
9 essentials at a glance
Watering
Monstera standleyana 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 drains well to avoid waterlogging. In fall and winter, reduce watering to every 2-4 weeks. Signs of over-watering include yellowing leaves and a mushy stem, while under-watering may cause leaf curling and browning 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, which can scorch the leaves. If placed in lower light, growth may slow down, but the plant will still survive.
Soil
Monstera standleyana prefers a well-draining potting mix, ideally a blend of peat, perlite, and orchid bark.
The pH range should be between 5.5 and 7.0. Ensure the pot has drainage holes to prevent root rot, as this plant does not like to sit in water.
Humidity
This plant enjoys high humidity levels, ideally between 60-80%.
To increase humidity, consider using a humidifier, grouping plants together, or placing a tray of water with pebbles beneath the pot. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Monstera standleyana thrives in temperatures between 65-85°F (18-29°C).
It is not frost-tolerant and should be protected from temperatures below 50°F (10°C). This plant does well in USDA hardiness zones 10-12, making it suitable for warm climates.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or a slow-release fertilizer during the growing season.
Fertilize every 4-6 weeks in spring and summer, and reduce to once every 2-3 months in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Monstera standleyana in spring to maintain its shape and promote bushier growth.
Use clean, sharp scissors or pruning shears to cut back any leggy growth or damaged leaves. Deadheading is not necessary, but removing yellow or brown leaves will improve the plant's appearance.
Repotting
Repot when the plant becomes root-bound, typically every 1-2 years.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs it needs repotting include roots growing out of the drainage holes or stunted growth. To repot, gently remove the plant from its 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. Change the water every few days if using water propagation. Roots should develop in 2-4 weeks. The best time to propagate is during the growing season in spring or summer.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives adequate light and humidity. Water regularly, keeping the soil moist but not soggy.
Fall
In fall, gradually reduce watering as the plant's growth slows down. Continue to fertilize until late fall.
Winter
In winter, water less frequently, allowing the soil to dry out more between waterings. Keep the plant in a warm location away from drafts.
Toxicity & Safety
Monstera standleyana is toxic to pets and humans if ingested. The leaves contain calcium oxalate crystals, which can cause irritation, swelling, and pain in the mouth and throat. Symptoms of ingestion include drooling, vomiting, and difficulty swallowing.
