Monstera Siltepecana, also known as the Silver Monstera or the Silver-Leafed Monstera, is a stunning climbing plant with unique, silvery-green leaves and striking fenestrations that develop with age. This tropical beauty is part of the Monstera family and shares many of the same care needs as its more famous cousin, the Monstera deliciosa. If you're lucky enough to add a Monstera Siltepecana to your collection, here's a guide to help you keep it healthy and thriving.
Monstera Siltepecana loves bright, indirect light. Ideally, you should place it in a location where it receives plenty of light but isn’t exposed to direct sunlight for extended periods, as this can scorch its leaves. A north or east-facing window is typically perfect, but if you're using a south or west-facing window, make sure to filter the light with sheer curtains.
If your plant is not getting enough light, it may become leggy and its growth may slow down. It’s best to ensure it receives ample indirect light to help it develop the signature fenestrations in its leaves.
Monstera Siltepecana likes to be watered thoroughly but prefers to dry out slightly between waterings. Check the top inch of soil to see if it feels dry; if it does, it’s time to water. However, it's important not to let the plant sit in water or stay too wet, as this can lead to root rot.
During the growing season (spring and summer), the plant will need more frequent watering, but in the winter months, you can reduce the watering frequency since it enters a period of dormancy. Always use room-temperature water to prevent shocking the roots.
Monstera Siltepecana prefers well-draining, airy soil. A high-quality potting mix designed for houseplants, mixed with perlite or coco coir, will work well to provide the right balance of moisture retention and drainage. The goal is to prevent the soil from becoming too soggy, as this can lead to rot.
Be sure to choose a pot that has good drainage holes to allow excess water to escape. If your plant starts outgrowing its pot, you can repot it into a slightly larger container every couple of years or as needed.
Being a tropical plant, Monstera Siltepecana prefers warm temperatures and moderate to high humidity. It thrives in temperatures between 65°F and 85°F (18°C to 29°C), and should not be exposed to temperatures below 50°F (10°C), as it can damage the plant.
As for humidity, Monstera Siltepecana will appreciate a humid environment. If you live in a dry climate or use air conditioning in the summer, consider increasing humidity around your plant. You can place it near a humidifier, mist it occasionally, or even place it on a humidity tray with pebbles and water to keep the air moisture level high.
During the growing season (spring and summer), Monstera Siltepecana can benefit from occasional feeding. Use a balanced liquid fertilizer diluted to half strength and feed it about once a month. Avoid fertilizing during the fall and winter months when the plant is not actively growing, as it won’t require additional nutrients during its dormant phase.
Be sure not to over-fertilize, as this can cause fertilizer burn and harm the roots. If you're unsure, it's always better to under-fertilize than overdo it.
Remove any yellow or damaged leaves to keep the plant looking tidy. You can also prune it to shape, especially if it becomes too leggy. Snipping back any unwanted vines will encourage bushier growth and help the plant stay compact.
To maintain its health, check for any pests regularly, as houseplants are prone to mealybugs, spider mites, and aphids. If you notice any pests, treat the affected areas with an insecticidal soap or wipe the leaves with a damp cloth.
Monstera Siltepecana is toxic to pets if ingested. Like many other plants in the Monstera family, it contains compounds known as calcium oxalates, which can cause mouth irritation and digestive upset in pets. To ensure your pets stay safe, keep the plant out of reach of curious cats, dogs, and other animals.
