How to Grow and Care for Mini Monstera

The mini monstera, or Rhaphidophora tetrasperma, is a tropical vine that makes for an easy-care houseplant, despite not being a true monstera. Known for its climbing habit and leaves with holes, this plant thrives in bright, indirect light, and prefers a well-draining soil mix and high humidity, much like other popular aroids. However, it's important to keep in mind that mini monstera is toxic to both people and pets.

Mini Monstera Care

Mini monstera care is similar to that of many common Monstera and Philodendron houseplants. Here are the main care requirements for growing a mini monstera:

• Plant in a well-draining potting mix that is slightly acidic.
• Place in bright, indirect light and avoid too much direct light, which can scorch leaves.
• Water thoroughly and keep soil consistently moist.
• Feed regularly with liquid fertilizer during the spring and summer months.
• Keep humidity high around mini monstera, if possible.

Light

Mini monstera grows best with several hours of bright, indirect light every day. Avoid exposing this tropical understory plant to direct sunlight as the leaves can burn easily.

If your plant starts growing leaves without fenestrations (or holes in the leaves), this is an indication that it needs more light and should be moved to a brighter location.

Soil

Plant your mini monstera in a moist but well-draining soil mixture that is nutrient-rich and slightly acidic. You can amend a regular indoor potting soil with some perlite and orchid bark, or combine one part coco coir, one part orchid bark, and one part perlite for best results.

Water

Native to tropical regions across Asia and Africa, mini monstera appreciate regular moisture and watering. Their delicate roots are sensitive to under-watering and overwatering, so keeping the soil consistently moist (and never soaking) is best.

If you're unsure about when to water, use a moisture meter. Water mini monstera just before the soil dry out.

Temperature and Humidity

Warm, humid conditions are best for mini monsteras. Typical household temperature levels are adequate for these tropical plants, as long as temperatures don’t dip below 68 degrees.

However, they usually appreciate some added humidity when grown indoors. To increase humidity around the plant, try placing the pot on a pebble tray or placing a humidifier nearby.

Fertilizer

Mini monstera should be fertilized regularly throughout the active growing period. Apply a balanced, liquid fertilizer once a month throughout the spring and summer to help support strong, healthy growth.

Types of Mini Monstera

While there aren't many cultivars of R. tetrasperma available, there is a variegated form, as well as a couple of other Rhaphidophora species of note:

• R. tetrasperma 'Variegata’: This mini monstera has dramatically variegated leaves that are deeply serrated. It packs a bold punch into a tiny plant.
• R. korthalsii: This plant doesn't have instantly recognizable leaf fenestration, but instead, it has vibrant green, heart shaped leaves that form a lush trail as they climb.
• R. pertusa: With a classic fenestrated leaf Monstera look, this vine has dark green foliage that is striking in any room.

Pruning

Pruning your mini monstera encourages growth, so prune from the top if you want it to continue to grow upwards. Pruning from the sides will encourage a bushier plant. Leaves that are old should also be pruned to keep the plant healthy.

Propagating Mini Monstera

Mini monstera are best propagated by stem cuttings. If you need to cut your plant back to control its size at any point, this is a great way to reuse any cuttings to create a new plant or fill out your existing plant.

Follow these simple steps to propagate your plant using stem cuttings:

1. Using a sharp pair of pruning shears or scissors, take a stem cutting from a mature, healthy plant that has at least 2-3 nodes along the stem.
2. Remove any leaves from the bottom 1-2 nodes of the stem, and submerge the exposed nodes in water using a glass or small vase.
3. Place the stem cutting in a location that receives medium to bright indirect light, and change out the water once a week.
4. Once the cutting has roots that are at least 1-2 inches long, it can be transferred back to a pre-moistened soil mixture.
5. Ensure that you keep the soil consistently moist to allow the new roots to acclimate to growing in soil.
   

Potting and Repotting Mini Monstera

Plant in a pot with well drained, slightly acidic soil that is fertilized regularly throughout the spring and summer growing season. Mini monstera should also be grown with a support to aid its climbing growth habit.

A trellis or pole will encourage the plant to climb. Mini monstera should be repotted if it appears to be outgrowing its original planter. Move the plant into a container one size larger filled with fresh potting mix.

Helping mini monstera climb

Mini monsteras are climbers, so when potting or repotting, provide some type of support. These plants will cling to anything, including the wall, but they'll thrive if their aerial roots have a moist medium to grow into, such as a sphagnum moss pole. Mist the sphagnum regularly.

Common Pests & Plant Diseases

When grown indoors, mini monsteras are susceptible to a number of common houseplant pests. Keep an eye out for spider mites, fungus gnats, and scale in particular, and treat with an appropriate insecticide at the first sign of an infestation.

Additionally, mini monstera can suffer from diseases including bacterial leaf spot and fungal diseases like root rot and rust fungus.

Common Problems with Mini Monstera

Mini monstera plants are easy to grow indoors as a houseplant and generally don’t have too many problems. That being said, common problems that can arise with this tropical plant are usually related to improper watering or lighting conditions, which luckily are easy to fix.

Yellow Leaves

Yellowing leaves can be indicative of a few potential problems, but the most common culprits are overwatering and a lack of light. Try moving your plant to a brighter location and cutting back on watering slightly to see if this improves the issue.

Curled, Drooping Leaves

Due to their sensitive roots, if your mini monstera is left to dry out for too long it is possible for the roots to start drying up and dying, which will result in leaves that curl and droop downwards as a result of a lack of moisture.

If the roots are too far gone, watering your plant will not resolve the issue as it won’t have the root system to absorb the water. If this is the case, remove your plant from the soil and place it in a vase filled with water for a few weeks to allow new roots to grow.

Then, once the root system has been reestablished, you can transfer the plant back to pre-moistened soil.

Brown, Crispy Edges

Leaves with brown, crispy edges and spots usually indicate a lack of moisture and humidity. Ensure that you are keeping the soil consistently moist, and try increasing the humidity around the plant with a humidifier or pebble tray.
