Monstera Siltepecana is a rarer plant that is part of the Araceae family, native to Central America and Mexico. In the rainforest, this species of plant is known to start growing at the base of a tree as a juvenile and will climb up the trunk as it matures.

The Monstera Siltepecana has two different appearances in its lifetime. When the plant is a juvenile, the leaves are a bluish grey colour with shades of silver. Once the plant matures, the leaves become a darker green colour and eventually develop fenestrations (holes in the leaves).

Since this type of plant loves to climb, it will grow best when given a pole to climb up. However, this plant will also look amazing in a hanging basket or even in terrariums. Not only does this plant look good, it’s also super easy to propagate!

Size

When kept indoors with the correct care, you can expect the leaves of a juvenile Monstera Siltepecana to reach the size of 2-3 inches long and 2 inches wide.

As your plant ages you can expect full size mature leaves to reach a length of 4-5 inches in length. For your plant to develop more mature leaves indoors, you will need to provide it will a sturdy pole and give it time.

Monstera Siltepecana will grow to be around 4 metres in length as a fully developed plant. So make sure to give it plenty of room and poles to climb on.

Monstera Siltepecana Light Requirements

Light is super important when it comes to growing plants indoors as insufficient lighting can cause growth problems. These problems include yellowing leaves, stunted growth, loss of colour and the leaves growing further apart. Browning leaves can be a sign that your plant is not getting enough light or has been over-watered.

Monstera Siltepecana will grow best when positioned in a spot with bright indirect light. Allowing your plant to get some full sun exposure is fine, especially if it’s morning sunlight through an east facing window. However, it’s important that you don’t leave the plant exposed to full sun for too long as the sunlight can burn the foliage. You can add a curtain or blinds to the window to help diffuse the sunlight so the leaves don’t burn.

Temperature

Monstera Siltepecana plants prefer temperature conditions that range from 50˚F (10˚C) to 95˚F (35˚C). Even though this plant is pretty tolerable too high temperatures, it’s better to try and keep your plant inside this temperature range if you can.

Humidity

Since Monstera Siltepecana are native to rainforests, thus they prefer a higher humidity. They will still grow in lower humidity conditions but for best growth, adjusting the humidity will be best. Browning leaves or leaf tips can be a sign that your plant is in a spot where the air is too dry.

Monstera Siltepecana Watering Requirements

With this species of plant being native to rainforests, this means it will require a good quantity of water. Drooping leaves can be a good indicator that your plant needs water but as a rule of thumb, you should check the top 2-3 inches of soil with your finger to feel if the soil is moist. If the top layer of the soil is dry, you should give your Monstera Siltepecana some water. It’s important that you water thoroughly and allow the water to drain completely. Drooping or curling leaves can also be a sign that your plant needs water.

If you let your Monstera Siltepecana dry out too much between watering, you may notice the lower leaves turning yellow. As a general rule, you can water your plant at least once a week. Always check the plant before watering as you don’t want the soil to stay too soggy for too long. Allowing the soil to stay too soggy can quickly cause issues like root rot. Yellowing leaves can also be a sign of over-watering.

Fertilizing requirements

When fertilizing Monstera Siltepecana, you can use any of the common houseplant fertilizers diluted in water. In optimal conditions, you should fertilize your plant once a month during the growing period. During the cooler months you can reduce how often you fertilize. An alternative too using liquid fertilizer is using a slow release fertilizer. Apply slow release fertilizer as per instructions on the packaging.

Fertilizing your Monstera Siltepecana will assist in keeping your plant alive as well as promote new and healthy growth. If you notice your Monstera Siltepecanas leaves are looking discoloured, this can be a sign that your plant is malnourished. The leaves may look pale or yellow in colour and the veins clearly visible.

Soil Requirements

Monstera Siltepecana requires a soil that is loose and well draining. Adding perlite and/or orchid bark to any general potting mix will be best to assist in drainage. It’s important that you don’t use a soil mix that stays too soggy as this can cause the roots to rot.

Diseases & Pests

The most common pests that you can encounter whilst caring for your Monstera Siltepecana are Spider Mites, Mealybugs, Scale and Aphids. Some of the common diseases you may encounter are root-rot and leaf spot. For a wide range of information on combating a range of indoor plant diseases and pests click here.
