Monstera Siltepecana Complete Care Guide

Monstera Siltepecana is one of my favorite plants, I love how it looks, I love how fast it grows, I love to propagate it, I love everything about it 😍

Scientific name: Monstera Siltepecana

Also called: Silver Monstera

Family: ARACEAE

If you learn better by watching videos, this blog post also has a video care guide heheh:

care meter: 9/10

It’s almost perfect, I would give it a 10/10 but I may be biased because I love it so much. I didn’t face any problem with it and I highly recommend it to anyone. Monstera Siltepecana loves life.

light

Monstera Siltepecana loves bright indirect light. It will grow like crazy if the light is right. And it also grows very well under growlights. It is a very rewarding plant that has a similar growth pattern with Cebu Blue pothos for example.

Light is very important for Monstera Siltepecana, and lack of it may cause yellowing leaves. If you see this sign, try to place it somewhere else or help it with artificial lights.

watering

Silver Monstera likes the soil to be almost dry before watering. You can water it once a week during warmer times, and once every 10-14 days during winter.

Excess water may lead to root rot so don’t give it too much love. Check the soil every time before watering.

temperature

Monstera Siltepecana can thrive in average temperature, something between 20-25°C is great. Mine is growing at 22-23°C and it’s doing well.

Whatever you do, please don’t let it drop below 15°C for too long. In general plants like this, don’t do well in colder rooms. Leaves may suffer and it will slowly die.

humidity

Monstera Siltepecana likes humidity all day long. Something above 60% is going to give you juicy arial roots perfect for propagation.

It can adapt to average humidity, but we wouldn’t recommend something below 40%. If the air is dry, you can definitely help your plants with a humidifier.

fertilizer

Silver Monstera can be fertilized every month during growing season. It’s best to use a balanced fertilizer, with an NPK of 10-10-10. Or a regular fertilizer for houseplants will do just well.

I fertilize my Monstera Siltepecana during winter as well, because it doesn’t stop growing. 😍 Cool thing huh. Because room temperatures are lower this time a year, I use a more diluted fertilizer just in case.

substrate

A simple mix for Monstera Siltepecana can be made of coco fiber, perlite and pine bark. (In equal quantities) The substrate has to drain water fast. Monstera Siltepecana is not water loving so the soil should be light.

Anything you use, please make sure the soil is drying relatively fast.

plastic versus terracotta

Monstera Siltepecana can live in plastic and terracotta just fine. It’s just a matter of preference.

Please make sure you check the soil more often if you chose terracotta. Being porous, it helps the water evaporate more quickly.

repotting

Monstera Siltepecana grows pretty fast so check the bottom of the pot for visible roots. Once the roots are crowded, it’s safe to repot.

Chose a pot slightly bigger, and you’re good to go.

If you just bought the plant, please wait at least one month before repotting. It’s not great for plants in general to be repotted just after they changed the growing environment. It causes more stress that could’ve been avoided.

propagation

My favorite method of propagation is by stem cuttings. Cut your vine into segments containing at least a node, place them in water and wait for the magic to happen.

The aerial roots are very helpful in this case. Or in case of propagation directly into soil. (Sphagnum moss or coco fiber is great for this).

pests


I didn’t have any problems with Monstera Siltepecana, but if there has to be one, maybe thrips could start to challenge you.

If we don’t have it already, we’ll write an article about every single annoying pest and how to deal with them. Until then, check the plant every time you water it to spot those tiny bastards in time.

toxicity

Unfortunately, Monstera Siltepecana is toxic for our pet friends. In case of ingestion please contact your local vet. It could cause irritation, nausea or other nasty side effects.

Other tips and tricks to consider:

  • Humidity is key for Monstera Siltepecana. I’ve never seen so many aerial roots on a plant this size before and I love it.
  • Grown on (sphagnum) moss poles, Monstera Siltepecana could look totally different. Those silvery leaves we are seeing, are juvenile. Mature leaves are fenestrated and not at all silver. It’s very hard to get that indoors though, unless you have all the right answers.
