First found in 1889 in Guatemala by John Donnell Smith, the Monstera Siltepecana can be located in the wild in southern Mexico and Central America. Specifically, it has also been collected in Chiapa, Mexico, Belize, Columbia, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. This is not too rare of a monstera. Like other monsteras, it will eventually develop some fenestrations in the leaves as it matures. However, the fenestrations will definitely not be as prevalent compared to other monsteras. The Monstera Siltepecana is known for its unique silvery coloration and elongated, oval leaves.
Monstera Siltepecana Light Needs
As with the majority of other monsteras, the Siltepecana likes bright, indirect light. The more indirect sunlight you provide, the bigger and shinier the leaves will be. However, do not leave your monstera out in direct sunlight all day long. Place it a few feet away from a south or west-facing window for it to be happiest.
Water your Monstera Siltepecana once the top 50% of soil is almost dried out, check it weekly. Then, evenly soak the soil and allow the excess to drain out. Depending on the size of your pot, the time frame for watering again could vary greatly. The best way to know when your Monstera Siltepecana needs water is by sticking an entire finger into the soil. If it feels dry, then water.
Use a balanced feed. Only fertilize during the growing season and diluting the fertilizer to half strength is a good idea. The Monstera Siltepecana is sensitive and does not require a high amount of fertilizer. Provide a ½ dose of fertilizer once a month in the spring and summer. Watch your plants for signs of fertilizer burn such as yellow spots, leaves curling, or brown on the edges of the leaves. If this happens, lessen the frequency you fertilize. Likewise, if you do not notice your fertilizer is making a difference in the growth of your Siltepecana, you may want to up the dosage or fertilize slightly more frequently. It all depends on your individual plant and the size of your pot.
Like other monsteras, the Siltepecana needs a well-draining aroid mix. Add perlite, and orchid bark, horticultural charcoal, and sphagnum moss. Ensure that there are some air pockets around the roots of your monstera so that they do not begin to rot or be suffocated by water.
They can also be grown in leca/semi-hydro or sphagnum moss.

The Monstera Siltepecana can be a very fast grower if you provide it the right conditions. So, keep an eye on the drainage hole of your pot for roots. Only reply if the roots begin to climb outside of the bottom of your pot. The timeframe for reporting depends on the age and size of your monstera, however, you can expect to repot around every 2 years. This is also a good time to give your plant some fresh potting mixture too.
Monstera Siltepecana Humidity
The best level of humidity is above 60%. If your monstera is kept at a lower level, you may not get leaves growing to their full size potential. The plant may also grow slower overall. The best location to provide a consistent level of humidity above 60% would be inside a glass cabinet. If you don’t have this available, set up a quality humidifier. Many humidifiers today come with a built in hygrometer to keep track of the surrounding air.
This monstera can tolerate a wide range of temperatures and adapt quickly. Temperatures between 61-86 degrees fahrenheit (16-30 degrees celsius) is the range that it can live in. This is a plant that will enjoy being kept outside during the summer in a shadier area. Just be sure to not keep it out overnight if temperatures will be dropping.
How to Propagate Monstera Siltepecana
You can propagate this Monstera similarly to other trailing or climbing plants, by stem cuttings. Find a node, which is the area the leaf comes out of the stem. You need one leaf and one node. Then leave it to callous over for a few hours so the wound is shut. Then put the leaf cutting into water and make sur the node is submerged and the leaf is not touching the water (which can rot it). You then need to wait for it to root. They should start growing soon, but be fully formed in a month or two, when you can move them to soil.

Monstera Siltepecana Vs El Salvador
The el salvador is a type of siltepecana, but it has more silvery leaves, colored like a dubia.
Monstera Siltepecana Vs Peru
The siltepecana is more of a vining plant than the peru, which grows in a bushier fashion, although they are both vining plants. The peru has bullate, more blistered leaves.
Other than its main name of Monstera Siltepecana, this plant is also referred to as the Silver Monstera due to the lovely colors on its leaves. All Monstera are also commonly called the Swiss Cheese Plant because of the holes in the leaves they eventually develop when they are mature.

Monstera Siltepecana Common Pests, Issues, and Treatments
The most common pests for the Monstera Siltepecana are spider mites, mealy bugs, scale, and aphids. These all can be treated by using an organic insecticide or a mixture of neem oil sprayed on the leaves. Don’t forget the undersides! You can also pick off the larger bugs like mealy bugs and aphids by hand or with a q-tip.
Another issue that you may notice will be yellowing leaves, this is often caused by fluctuations in watering or by a potting soil that is too wet. Make sure to water only when the top 2 inches (5 cm) of soil are dry. If this keeps occurring, then switch out your potting soil for one with increased airy ingredients.
