How to Grow and Care for Swiss Cheese Plant

The Swiss cheese plant (Monstera adansonii) gets its common name from its large, heart-shaped leaves that develop holes as the plant ages (in a process called fenestration). This makes the leaves resemble Swiss cheese. Native to Central and South America, the Swiss cheese plant is a tropical perennial that’s typically grown as an indoor plant.

Monstera epipremnoides

‘Swiss Cheese Plant’ is named so because of its huge leaves with holes in them that resembles Swiss cheese. Leaf shape changes as the leaves mature from entire to having holes to eventually having perforations often extending to and breaking through the outer edges of the leaves and result in a pinnatifid leaf shape. It is an evergreen epiphytic vine that grows up to 13′ tall.

This plant is intolerant of direct sunlight and wet soil. It prefers interior environments with moderate light and average humidity. It needs rich, well-drained soil that is not allowed to dry out completely. A good soilless recipe works well. It is easily propagated by cuttings. It has no serious pest or disease problems.

The Swiss cheese plant (Monstera adansonii) gets its common name from its large, heart-shaped leaves that develop holes as the plant ages (in a process called fenestration). This makes the leaves resemble Swiss cheese. Native to Central and South America, the Swiss cheese plant is a tropical perennial that’s typically grown as an indoor plant.

Like its cousin Monstera deliciosa (also referred to as the Swiss cheese plant), Monstera adansonii has a fast growth rate and a vining habit. But it will remain at a manageable size when grown in a container indoors. When cultivated as a houseplant, Swiss cheese plants are typically grown from young nursery plants and can be potted at any time. It’s important to note that all parts of Monstera plants are toxic to pets, so be careful when growing them indoors.

Light

Because of the Swiss cheese plant’s tropical origin, Monstera adansonii needs sunlight, but it’s best if the light is bright and indirect. It’s used to thriving under the cover of large trees in the jungle, and the foliage can easily burn if it’s exposed to too much direct sun. If direct sunlight is unavoidable, limit exposure to just two or three hours of morning sun.

Soil

Swiss cheese plants grow best in peat-based potting mix, which will help to trap moisture in the soil without causing it to become waterlogged. For strong growth, aim for a soil pH between 5.5 and 7.

Water

These plants like to be consistently moist but not soaked. Before watering your Swiss cheese plant, stick your finger into the soil about an inch deep. If the soil feels nearly dry to the touch, it’s time to water the plant. Irrigate until a little water runs out of the container’s drainage holes.

Temperature and Humidity

These jungle plants thrive in very high humidity and warm temperatures. The closer you can mimic the plant’s natural conditions, the better. Make sure your plant always remains in a spot that’s above 40 degrees Fahrenheit, and protect it from drafts. A humidity level above 50 percent is ideal. A warm, well-lit bathroom is a good spot for this plant. If you need to increase humidity, mist the plant or use a humidifier in its space.

Fertilizer

After potting (or repotting) the plant, wait at least four to six months to fertilize it, as potting mix typically already has slow-release fertilizer in it. After that, fertilize your Swiss cheese plant monthly, using an all-purpose liquid fertilizer that has been diluted by half.

Types of Swiss Cheese Plant

There are several species that bear the name of the Swiss cheese plant, including:

• Monstera deliciosa: This species features leaves that are larger than those of Monstera adansonii.
• Monstera borsigiana: This is a smaller and faster-growing form of Monstera deliciosa.
• Monstera obliqua: This is a rare species that looks similar to Monstera adansonii, but its leaves are thinner with more holes.

Pruning

The Swiss cheese plant is a climber, so it might need to be pruned if it begins to outgrow your space. Should you need to prune your plant, aim to do so in the spring. Use sterile pruning shears to cut back stems by no more than 25 percent. Cut just the stem right above a leaf node so it stays in place. Also, remove any dead or damaged leaves as needed.

Propagating Swiss Cheese Plant

The easiest method to propagate a Swiss cheese plant is by stem cuttings. Not only is this an inexpensive way to acquire new plants, but it allows you to put any stems you remove while pruning to good use. The best time to propagate is in the spring. Here’s how:

1. Trim off a 4- to 6-inch piece of stem, cutting just after a leaf node (the node stays intact). Remove any leaves on the bottom third to half of the cutting.
2. Apply a rooting hormone to the cut end.
3. Plant the cutting in moistened soilless potting mix in a small container with drainage holes. Place it in a warm spot with bright, indirect light.
4. Continue to keep the growing medium lightly moist. You should have well-formed roots in a few months, after which you can transfer the cutting to a larger pot.

How to Grow Swiss Cheese Plant From Seed

To grow a Swiss cheese plant from seeds, plant them in a shallow tray filled with a moistened seed-starting mix. Lightly cover the seeds with the growing medium. Put plastic wrap over the tray to trap moisture, and place it in a warm spot with bright, indirect light. Mist the growing medium to keep it lightly moist. The seeds should germinate in a few weeks. After that, remove the plastic wrap but continue to keep the growing medium moist. The seedlings should be large enough for transplanting in a few months.

Potting and Repotting Swiss Cheese Plant

Any container with drainage holes will do for a Swiss cheese plant. These plants look especially nice in hanging baskets. When potting a nursery plant, select a container that’s just slightly larger than the plant’s root ball. Situate it at the same depth as it was in its nursery container, using a peat-based potting mix. Plan to repot every two years in a slightly larger container with fresh potting mix. The best time for potting and repotting is in the spring.

Common Pests and Plant Diseases

The Swiss cheese plant might have to contend with a variety of common houseplant pests, including mealybugs, spider mites, scale, and whitefly. Luckily, these pests are rarely fatal and can be treated with a nontoxic insecticide or neem oil. Additionally, keep an eye out for common diseases, such as root rot, rust, powdery mildew, and blight.

Common Problems With Swiss Cheese Plant

When grown in the conditions it likes, the Swiss cheese plant typically doesn’t have any serious problems. However, if you can’t meet its environmental needs indoors, it is prone to some common issues.

Leaves Turning Yellow

Yellowing of the leaves is commonly the result of overwatering. Make sure your plant is never sitting in soggy soil, and allow it to slightly dry out between waterings.

Leaves Turning Black

Black marks on the leaves can be a sign of leaf burn from direct sunlight. Watch your plant throughout the day to make sure direct sun isn’t hitting it for very long. Especially make sure to protect it from strong afternoon sun.

As long as you can provide warm, humid conditions, Swiss cheese plants are relatively simple to maintain.

How do you know if your Monstera adansonii is happy?
A happy Swiss cheese plant will have deep green waxy leaves and no discolorations.
Why are Monstera adansonii variegated plants so expensive?

Variegated Swiss cheese plants can be expensive, but that’s because this popular plant is rare. They may sell out quickly when you spot them for sale.
