All About Monstera Deliciosa Care
Swiss cheese plant, Mexican Breadfruit Plant, Split-leaf philodendron
Monstera Deliciosa is a large aroid native to Central America. It is named for the edible fruit “deliciosa” and abnormal leaves “monstera”. This showy plant is a favorite among hobbyists and is grown in homes all over the world. Monsteras are loved for their ease of care and dramatic appearance.
Young plants have tall stems with heart-shaped leaves (shown below). As the plants mature, the leaves develop more holes and splits giving it the nickname Split-leaf Philodendron; although it is not a true philodendron. It is rare to see the most mature leaf pattern (shown above) in home environments.
Tips for Monstera Deliciosa Care
Monsteras are from tropical regions where they grow along the forest floor. Once they find something to climb, they use their aerial roots to attach to and grow up trees. They are understory plants that love bright, indirect light. Just as they get growing under trees.
The large leaves of Monsteras are more likely to sunburn than smaller-leafed plants. Take care when moving monstera outdoors for the summer. They’ll need a shady porch and a few weeks to acclimate to the increase in light. Once they are accustomed to higher light, they’ll love it. Tip: move your plant closer to the light over a 2-3 week period. A little closer every day.
The average temperature and humidity in most home environments is perfect for these tropical plants. If you live in an arid region, consider ways to increase humidity.
They need a deeper pot than most houseplants to make room for their thick roots. Once your plant has significant foliage growth, you’ll also need a pot heavy enough to counter the weight of the foliage. If the pot is too light, the plant will continuously fall over from the foliage weight. You can pot them up an inch or two once the roots start growing out of the bottom of the pot; however, they prefer to be slightly root bound.
Many hobbyists prefer to grow Monsteras on totem or moss poles. This gives the aerial roots something to attach to and trains an upright growth pattern. If you prefer to have a wider, bushy plant, don’t use a moss pole. Check out our article on How to Make a Moss Pole.
Care Summary
Zone
The ideal temperature range is 60° – 90 ℉
Monsteras prefer warm, humid conditions.
Monstera can be invasive. Use caution if growing outside of its native habitat.

Water
They don’t like to completely dry out like a cactus would.
Water when the top 2-3 inches of soil is slightly dry.
If you are unsure, stick your finger in the soil.
Too much water can cause root rot.
Size
These are called monsters for a reason.
Indoors they grow to 3 feet tall and wide.
Outside they can grow to 30 feet tall.
Light
Bright, indirect light but can grow well in medium-light situations.
Grow in shade outdoors.
Direct summer sun can cause sunburn if not acclimated.
Variegated plants need significant light in order to maintain healthy variegation.
Soil
Use a rich potting mix that is loose, airy, and drains well.
Add orchid bark and perlite to regular soil to improve drainage.
Alternatively, you can make your own aroid mix that can be used for all of your aroids.
Humidity
Ideally 50% or higher humidity levels.
They can tolerate short periods of lower humidity, especially while semi-dormant during winter months.
Native to tropical regions of Central America.
Toxicity
The roots and leaves of Monsteras are toxic.
The fruit is the only edible part of the plant.

Fertilizer
Fertilize every during the growing season.
Once every three months with Green Grub Insect Frass.
For synthetic, use an all-purpose houseplant fertilizer with a balanced ratio.

How to Propagate Monstera Deliciosa
Monstera Deliciosa propagation is easy peasy. Once your plant is mature, you’ll likely have no choice but to prune it every few years so why not take those cuttings and spread the love with new plants?
There are four ways to propagate – seed, division, air layering, and stem cuttings. Growing from seed takes a long time so we will discuss division, air layering, and cuttings here. All methods are best done in the spring or during active growth. Tip: ground cinnamon can be applied to cuts to help close the wound and prevent infection on plants.
Division
1. This is easily done while repotting your plant. Once you have the rootball out of the pot, use a sharp knife to cut individual offsets away from the main plant. Make sure to get enough roots to support the new offset.
2. Likewise you can also loosen the rootball with your fingers and gently separate the offset from the main plant.
3. Plant your new offset into a rooting medium, keep moist and wait for the plant to establish.
4. Once your offset is established and growing well. Repot into a pot that is 1 inch larger than the rootball and enjoy your new plant!
Stem Cuttings
1. Take cuttings of healthy stems making sure to get the node. The “node” is where the aerial root grows. This aerial root or node will change into soil roots. Without the node, no roots will grow.
2. Plant the stem with node(s) into a rooting medium and keep the growing medium moist, not wet. Ensure that the node is in the rooting medium, not above it.
3. If possible cover with a clear plastic or glass dome so that the leaves do not dry out. Seed starting kits and propagation boxes work well for this.
4. Place your cuttings/ prop box in a warm area with bright indirect light and keep growing medium moist, not wet.
5. Wait for new growth. Once you have a thriving plant-let, repot, and slowly acclimate to a less humid environment.
6. Monstera Deliciosa also roots very well in water. Use a clear glass of water and place the node below the water line. Put the glass in a warm, sunny spot and change the water weekly. Wait for roots to grow, then pot in loose soil.
Air Layer
1. Choose a stem with 3 or more nodes.
2. Using a clean, sharp knife cut a notch right below the node, about 1/3 into the stem. Don’t sever the stem, just create a wound.
3. Wrap a 1-inch layer of moist sphagnum moss around the node and wound.
4. Wrap the moss in plastic wrap and secure it with ties. Not tight enough to damage the stem but not so loose that it’ll fall off.
5. Once roots have developed, cut off the “new” plant. Cut where the original wound was created and sever the stem. Plant the “new” plant in loose soil.
Aroid Mix Recipes for Monstera Deliciosa
The following are a few recipes you can try for making your own aroid mix. Different people prefer different mixes according to their plant care style and environmental needs.
I prefer to use regular indoor potting soil and add amendments as needed. For example, if my plant isn’t drying out in time for the weekly watering, I’ll repot and add perlite to aid in drainage. Conversely, if it drys out too fast, I’ll repot and add coconut coir to retain moisture.
Basic Mix
1/2 Regular potting mix
1/4 Perlite
1/4 Orchid Bark
1 to 1 Mix
Orchid Bark
Compost or Natural Fertilizer
Perlite
Potting Soil
Coconut coir or Peat moss
1234 Mix (Soil)
1 Part Insect Frass (or castings)
2 Parts Soil
3 Parts Perlite
4 Parts Orchid Bark
1234 Mix (Coir)
1 Part Insect Frass (or castings)
2 Coconut coir or peat moss
