How to grow and care for Silver Monstera Indoors

Houseplant, Silver Monstera, Monstera siltepecana

Botanical name: Monstera siltepecana
Family: Araceae

Silver Monstera also called Siltene Monstera is an evergreen vine which exhibits two different appearances in its life stages. This unique 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 are bluish-gray with distinct dark-green veins. As it ages, the leaves become larger, dark-green and develop fenestrations (holes). The leaves will remain in the juvenile stage if the plant is grown in a terrarium or in a hanging basket. If allowed to climb on a trellis or sturdy pole, the plant will begin to produce mature leaves. Silver Monstera is native to the tropical rainforests of Mexico and Central America. The plant is sometimes incorrectly called Silver Queen Philodendron or Philodendron siltepecana.

How to Grow Silver Monstera (Monstera siltepecana)

Light

Silver Monstera prefers bright indirect light away from direct sunlight as it can cause sunscorch on the leaves. Place it next to a sunless window or near a bright window. Learn how to ensure your plant receives the correct light in this guide on understanding light for houseplants.

Water

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. Avoid waterlogging as it can lead to Root-rot Disease which can result in the eventual death of the plant. Learn more on how to water houseplants.

Temperature

Average warmth with a minimum of 150C is ideal for Silver Monstera. Protect the plant from cold draughts. Learn more on temperature for houseplants.

Humidity

Average room humidity is ideal for Silver Monstera. When the air is too dry, employ these techniques to raise humidity for the vine. Occasionally clean the leaves by damp-wiping with a soft cloth to get rid of dust and also discourage pest infestation.

Feeding

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. Learn more on how to feed houseplants.

Repotting

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. The soil should be free-draining and rich in organic matter. Ensure the pot has a drainage hole(s) to prevent waterlogging which can lead to root-rot.

Pruning

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

How to Propagate Silver Monstera (Monstera siltepecana)

Silver Monstera can be propagated at the beginning of the growing period by use of stem cuttings or by air layering.

Propagating 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 plant. Insert the cutting in moist free-draining soil. Place in a shaded well-lit place and maintain the soil moist until new growth emerges. Allow the new Silver Monstera to be well established before transplanting.

Propagating 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 plant. Place the cutting in a jar containing plain water. Place the set up in a well-lit spot and change the water every 7-10 days. Once adequate roots have developed, plant the cutting in soil and place in a shaded well-lit place. Allow the new Silver Monstera to be well established before transplanting.

Common Problems in Growing Silver Monstera (Monstera siltepecana)

  • Yellowing leaves
  • Overwatering Silver Monstera is the reason if many leaves are affected and there are signs of wilting and rotting but if there is no wilting and rotting, underfeeding is the cause. If only lower leaves are affected and have dark spots and new leaves are dark and small; underwatering is the reason. If leaves are pale colored and have straw-colored patches the problem is too much sunlight.

  • Loss of leaves
  • As the lower leaves of Silver Monstera age they fall but if there is an abnormal loss of leaves the reason is sudden change of growing conditions. If the leaves turn brown and dry before they fall then high temperature is the cause.

  • Rotting stems
  • The reason for rotting stems in Silver Monstera is the fungal Stem-rot Disease which is promoted by high moisture and too little warmth. You can save the plant by repotting and keeping the soil dry and warm.

  • Leaves with brown papery tips and edges
  • The reason for leaves with brown papery tips and edges in Silver Monstera is dry air; employ these techniques to raise humidity or the plant may be pot-bound; repot in a larger-sized pot.

  • Leggy growth, small pale leaves
  • Too little light is the cause as Silver Monstera will not thrive in deep shade; move the plant to a more brighter spot.

  • Leaves weeping at the edges
  • If the soil is too wet, 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.

  • Diseases
  • The most common disease in Silver Monstera is Leaf Spot.

  • Pests
  • Common pests in Silver Monstera are Mealy Bugs, Scale Insects, Aphids, and Spider Mites. Isolate the plant to prevent further spread to other plants.

Toxicity

Silver Monstera (Monstera siltepecana) is mildly toxic to humans and toxic to pets. If ingested it can cause pain and swelling in the mouth, tongue and lips, vomiting, excessive drooling and difficulty in swallowing.
