Silver Monstera, Monstera siltepecana

Botanical name: Monstera siltepecana
Family: Araceae
Common names: Silver Monstera, Siltene Monstera

Silver Monstera Description

Silver Monstera also called Siltene Monstera is an evergreen vine which exhibits two different appearances in its life stages. This unique Silver Monstera can be grown as a climber on a trellis or pole, in a hanging basket or in a terrarium.

In its juvenile stage, the long, oval-shaped leaves in Silver Monstera are bluish-gray with distinct dark-green veins. As Silver Monstera ages, the leaves become larger, dark-green and develop fenestrations (holes).

The leaves will remain in the juvenile stage if Silver Monstera is grown in a terrarium or in a hanging basket. If allowed to climb on a trellis or sturdy pole, Silver Monstera will begin to produce mature leaves.

The Silver Monstera is sometimes incorrectly labelled as Silver Queen Philodendron or Philodendron siltepecana.

Silver Monstera Origin

Silver Monstera is native to the tropical rainforests of Mexico and Central America.

Silver Monstera (Monstera siltepecana) Care Indoors

Silver Monstera Light Requirements

Silver Monstera grows best in bright, indirect light away from direct sunlight as it can cause sunscorch on the leaves.

Position your Silver Monstera next to a sunless window or near a bright window. Check out this guide on understanding light for houseplants.

How to Water Silver Monstera

Water Silver Monstera liberally during the growing season and allow the top 2 in. of soil to dry out between waterings.

Reduce watering during the cold season to keep the soil slightly moist. Read more on how to water houseplants.

Ensure the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease and can result in the eventual death of your plant.


Temperature for Silver Monstera

The best temperature for growing Silver Monstera indoors is an average warmth with a minimum of 150C.

Protect your Silver Monstera from cold draughts to prevent sudden drop in temperature. Read more on understanding temperature for houseplants.

Humidity for Silver Monstera

Average room humidity is ideal for Silver Monstera. Where the air is too dry, set the pot on a wet pebble tray to raise humidity. Check out these techniques on how to raise humidity for houseplants.

Regularly clean the leaves by damp-wiping with a soft cloth to get rid of dust and also discourage pest infestation. Read more on how to clean houseplants.

Fertilizer (Feeding) for Silver Monstera

Feed Silver Monstera with a balanced water-soluble fertilizer every 4 weeks during the growing period.

Withhold feeding during the cold season as growth is minimal and feeding at this time may lead to fertilizer burn. Read more on how to feed houseplants.

How to Repot Silver Monstera

Repot Silver Monstera during the growing season when it becomes root-bound; when the roots grow through the drainage hole.

Use a pot 1 size larger and one that has a drainage hole for your Silver Monstera.

The best soil for Silver Monstera should be free-draining and rich in organic matter.

Ensure the pot has a drainage hole(s) to avoid getting soggy soil as it can lead to root-rot disease and eventual death of the plant.

How to Prune Silver Monstera

Pruning Silver Monstera is easy. Remove yellow and dead leaves to maintain the plant neat and tidy. Read more on how to prune houseplants.

Silver Monstera (Monstera siltepecana) Propagation

Silver Monstera propagation can be done at the beginning of the growing period by use of stem cuttings or by air layering. The stem cuttings can be rooted in soil or in water.

How to propagate Silver Monstera from stem cuttings in soil

Take a stem cutting from a healthy Silver Monstera by cutting at a point just below an aerial root. Just one leaf node with the leaf is enough to propagate a new Silver Monstera.

Insert the cutting in moist free-draining soil. Ensure the rooting container has proper drainage to avoid getting soggy soil.

Place the set up in a well-lit, warm place and maintain the soil moist until new growth emerges.

Allow the new Silver Monstera to be well established before transplanting.

How to propagate Silver Monstera from stem cuttings in water

Take a stem cutting from a healthy Silver Monstera by cutting at a point just below an aerial root.

Just one leaf node with the leaf is enough to propagate a new Silver Monstera.

Place the cutting in a jar containing plain water while ensuring that at least one leaf node is under water.

Place the set up in a well-lit spot and change the water every 5-7 days.

Once adequate roots have developed, plant the Silver Monstera cutting in soil and place in a well-lit shaded place.

Allow the new Silver Monstera to be well established before transplanting after which routine care can begin.

How to propagate Silver Monstera by air layering

There are two methods of air layering Silver Monstera.

One method consists of notching the stem of a healthy Silver Monstera and coating the notch with a rooting hormone.

Surround the notched area with damp moss and then cover it with a polythene film or clear plactic wrap.

After the roots have formed sever the stem just below the covered part.

Remove the polythene and carefully pot the rooted cutting in moist free-draining soil.

Place in a shaded well-lit place and maintain the soil moist until the new Silver Monstera is well established.

The second method involves coating the stem of your Silver Monstera at a node with a rooting hormone.

Surround the node with damp moss and then cover it with a polythene film or clear plastic wrap.

After the roots have formed sever the stem just below the covered part.

Remove the polythene and carefully pot the rooted cutting in moist free-draining soil.

Place in a shaded well-lit place and maintain the soil moist until the new Silver Monstera is well established.

Silver Monstera (Monstera siltepecana) Problems Indoors

Silver Monstera yellowing leaves

There are four possible causes of yellowing leaves in Silver Monstera.

One possible cause of Silver Monstera yellowing leaves is overwatering if many leaves are affected and there are signs of wilting and rotting.

Water Silver Monstera liberally during the growing season and allow the top 2 in. of soil to dry out between waterings.

The second possible cause for Silver Monstera yellowing leaves is underfeeding if there is no wilting and rotting.

Feed Silver Monstera with a balanced, water-soluble fertilizer every 4 weeks during the growing period.

The third possible cause for Silver Monstera yellowing leaves is underwatering if only lower leaves are affected and have dark spots and new leaves are dark and small.

Water your Silver Monstera liberally during the growing season and allow the top 2 in. of soil to dry out between waterings but never allow the soil ball to dry out completely.

The fourth possible cause for Silver Monstera yellowing leaves is exposure to direct sunlight if leaves are pale colored and have straw-colored patches. Protect your Silver Monstera from direct sunshine.

Silver Monstera losing leaves

As the lower leaves of your Silver Monstera age, they fall but if there is an abnormal loss of leaves the reason is sudden change of growing conditions.

Avoid sudden changes in the growing conditions for your Silver Monstera. Gradually acclimatize it to the new growing conditions before moving it to a new position.

If the Silver Monstera leaves turn brown and dry before they fall then high temperature is the cause.

Ensure your Silver Monstera is receiving an average warmth with a minimum of 150C.

Silver Monstera rotting stems

Rotting stems in Silver Monstera is an indication of fungal stem-rot disease which is promoted by high moisture and too little warmth.

You can save Silver Monstera by repotting and keeping the soil dry and warm for a period of time.

Silver Monstera brown papery leaf tips and edges

One possible cause of leaves with brown papery tips and edges in Silver Monstera is dry air.

Set the pot on a wet pebble tray to raise humidity for your Silver Monstera. Check out these techniques on how to raise humidity for houseplants.

The second possible cause of leaves with brown papery tips and edges in Silver Monstera is that the plant may be pot-bound.

Repot your Silver Monstera into a pot 1 size larger and one that has a drainage hole to prevent the soil from becoming soggy as it can lead to root-rot disease.

Silver Monstera leggy growth and small pale leaves

Too little light is the cause of leggy growth with small pale leaves as Silver Monstera will not thrive in deep shade.

Move your Silver Monstera to a more brighter spot where it is receiving bright light but away from direct sunshine.

Silver Monstera weeping at the leaf edges

If the soil is too wet, your Silver Monstera will respond with leaves weeping at the edges.

Allow the top 2 in. of soil to dry out between waterings and reduce frequency of watering for your Silver Monstera.
