Monstera Siltepecana, also known as the Silver Monstera, is a humble-looking plant that develops fenestration as it matures. It is easy to grow, tolerates low-light conditions, and is relatively easy to propagate. It is an exciting and rewarding addition to any plant collection.


Monstera Siltepecana requires bright, indirect light to thrive. It can tolerate some morning sun, especially from east-facing windows, but direct harsh sunlight should be avoided as it can harm the leaves. You can use grow lights as an effective solution if there is insufficient natural light. If you notice that the leaves of your silver Monstera are growing further apart and the plant looks sparse, it’s time to move it to a brighter location. If the leaves appear faded, it may be due to overexposure to sunlight.


This particular plant thrives in consistently moist soil, but it should not be waterlogged. It would be best if you watered it when the top inch of the potting mix dries out, which typically happens every 5 to 7 days. Be careful not to overwater, as Monstera Siltepecana is sensitive to waterlogging. Overwatering can cause root rot.


A well-draining potting mix is essential. An aroid mix with components like peat moss, perlite, pumice, orchid bark pieces, and charcoal is ideal. These ingredients ensure good drainage and aeration, which are crucial for the health of Monstera Siltepecana’s roots.


The ideal temperature range for Monstera Siltepecana is 60-95°F (16°C -35°C). Although it’s a tropical plant and prefers warmer temperatures, it can adapt to average household temperatures. Avoid placing it in areas with cold drafts or direct heating sources​


Maintaining high humidity levels above 60% is crucial for the growth of Monstera Siltepecana plant, as it imitates its natural tropical rainforest environment. If the indoor air is dry, using a humidifier can help increase the humidity levels around the plant. To further increase moisture, you can place the plants closer to each other, fill the bottom part of the pot with pebbles, spray the leaves daily, and place them in a comfortable and humid room. By following these methods, you can promote the growth of Monstera Siltepecana plant.


To keep your Monstera Siltepecana healthy, it’s recommended to use a balanced fertilizer once a month during spring and summer. Dilute the fertilizer to half strength to avoid over-fertilizing, which can harm the plant. During the autumn and winter when the plant’s growth slows down, reduce or stop fertilizing. The best fertilizer for Monstera Siltepecana is an NPK or Nitrogen, Phosphorus, and Potassium combination fertilizer with a 1:1:1 ratio.

Growth Rate

Monstera Siltepecana is known for its fast growth, often growing up to two feet per year under optimal conditions. Expect to repot it annually or at least every two years to accommodate its growth.​

Pet Safety

Monstera Siltepecana is toxic to pets if ingested. Keep it out of reach of children and pets.

Grow in Semi-Hydro

  • Monsteras, known for their robust growth and iconic split leaves, flourish in semi-hydroponics systems like LECA/Pon, thanks to their adaptive root systems and love for moisture.
  • Transitioning Monstera to semi-hydroponics is effective with a Nutrient Stagnant Wicking (NSW) setup, ensuring a stable and efficient growth environment.
  • In LECA/Pon, Monstera roots quickly adjust, overcoming any initial challenges with root adaptation in the NSW system.
  • A nutrient mix with a concentration of about 800-1000ppm is ideal for fertilizing Monsteras in semi-hydro setups.
  • Monsteras are adaptable to various temperature and humidity conditions, making them suitable for growth in diverse indoor environments.
  • Ongoing care includes regular monitoring of the water level in the reservoir and periodic flushing of the system to promote healthy and continuous growth.


  • Positioning: Place the Monstera Siltepecana near an east or north-facing window for optimal light exposure.
  • Watering Technique: Use the fingertip test to ensure the top inch of soil is dry before watering.
  • Humidity Management: If using a humidifier, set it to maintain humidity around 60%.
  • Soil Composition: Consider adding extra perlite to your potting mix for improved drainage.
  • Fertilizing Method: Dilute your fertilizer to half strength and apply it monthly during the growing season.
  • Repotting Time: Repot the plant when it’s rootbound, preferably during spring or summer.
  • Support Structures: Provide a climbing pole to encourage upward growth and larger leaf development.
  • Monitoring Growth: Watch for changes in leaf size and fenestration as the plant matures.
  • Regular Inspection: Check regularly for signs of over or underwatering and adjust your care routine accordingly.

These care tips will help you maintain a healthy Monstera Siltepecana, ensuring it thrives and adds beauty to your indoor garden. Remember, the key to successful houseplant care is observation and adaptability to your plant’s unique needs.

Happy planting! 🌱
