What You'll Learn

Swiss cheese plants thrive in humidity levels of 60-80%
Swiss cheese plants, or Monstera, are native to the rainforests of Central America and thrive in humidity levels of 60-80%. In their natural habitat, they grow under the canopy of trees, which provides them with bright, indirect sunlight and protects them from too much moisture.
To mimic these conditions indoors, place your Swiss cheese plant in a well-lit room, away from direct sunlight, and maintain humidity levels within the optimal range. You can increase humidity by misting the plant, using a humidifier, or placing the pot on a tray of pebbles and water. However, be careful not to overwater the plant, as this can lead to root rot and other issues. Allow the soil to dry out slightly between waterings, and ensure the pot has adequate drainage holes.
The distinctive holes in the broad, green leaves of Swiss cheese plants are a result of fenestration, which allows light to filter through to the lower shoots. These plants are known for their impressive, low-maintenance nature and can grow relatively fast, with leaves reaching up to three feet wide. They are mildly toxic, so keep them away from pets and children.
To ensure optimal growth, fertilize your Swiss cheese plant during the growing season (spring and summer) with a diluted liquid fertilizer every 2-3 weeks. Repot the plant every 2 years or when the roots outgrow the current container to refresh the soil and provide more space for healthy growth. Proper light exposure, temperature, and humidity are crucial for maintaining the health and vibrancy of your Swiss cheese plant.

They like moist, but well-drained soil
Swiss cheese plants, or Monstera, are native to the rainforests of Central America and thrive in moist environments. While they can tolerate some dryness, they prefer moist soil and high humidity. However, it is crucial to ensure that the plant is well-drained and not sitting in water for prolonged periods.
To achieve this balance, it is recommended to water your Swiss cheese plant when the soil is dry about one to two inches down. You can use a soil moisture meter and insert it into the first two inches of the soil. When this reads dry, you can begin watering. Ensure that the container has sufficient drainage holes to allow excess water to escape.
Overwatering can lead to root rot and other issues. Yellowing or browning leaves are common signs of overwatering. Therefore, it is important to allow the plant to dry out between waterings and ensure proper drainage.
Additionally, maintaining consistent humidity levels is essential for the health of Swiss cheese plants. They prefer humidity levels above 50%, and you can increase humidity by misting the plant or using a pebble tray. Grouping plants together can also help maintain humidity, and a warm, well-lit bathroom can be an ideal location for your Monstera.

They grow well in bright, indirect sunlight
Swiss cheese plants, or Monstera, are native to the rainforests of Central America and thrive in bright, indirect sunlight. They grow well in these conditions because, in the wild, they grow under the canopy of trees, allowing dappled light to reach their leaves.
When placing your Swiss cheese plant indoors, ensure it receives bright, indirect light by positioning it near a window. Avoid direct sunlight, especially during the hottest hours of the day, as this can scorch the leaves. If your home doesn't receive much natural light, you can supplement it with artificial lighting. However, the plant will still need some natural light, so consider moving it outdoors for a few hours each day or investing in a grow light.
The amount of light your Swiss cheese plant receives will impact its growth. If placed in low-light conditions, the plant's growth may slow, and it might become leggy as it stretches towards the light source. On the other hand, too much direct sunlight can lead to leaf scorching and wilting. Therefore, it is essential to find a balance by providing bright, indirect light for optimal growth.
Along with light, proper humidity and temperature are crucial for the health of your Swiss cheese plant. These plants prefer warm temperatures and humidity levels above 50%. You can increase humidity by misting the leaves, using a humidifier, or placing the pot on a pebble tray with water. However, ensure good airflow to prevent stagnant air and the risk of fungal infections.
By providing your Swiss cheese plant with bright, indirect sunlight, moderate temperatures, and adequate humidity, you will create an ideal environment for it to thrive and showcase its distinctive, lush foliage.

They are native to the rainforests of Central and South America
Swiss cheese plants, or Monstera, are native to the rainforests of Central and South America. They are known for their large, heart-shaped leaves, which develop holes as the plant matures, due to a process called fenestration. In the wild, some plants can tower up to 20 metres high. They are a popular choice for indoor plants due to their low-maintenance nature and fast growth. They grow well in bright, indirect light and warm temperatures, and they like lots of humidity.
In their natural habitat in the rainforests, Swiss cheese plants grow under the canopy of the trees, allowing dappled light to reach their distinctive leaves. The holes in the leaves of the Swiss cheese plant allow light to filter down to the lower shoots of the plant, ensuring that the entire plant receives adequate sunlight. This adaptation is well-suited to the plant's rainforest environment, where sunlight can be scarce on the jungle floor.
The rainforests of Central and South America provide the perfect climate for Swiss cheese plants, with high humidity and warm temperatures. These plants thrive in moist environments, and their native habitat provides an abundance of water vapour in the air. The humidity helps to keep the leaves lush and promotes unimpeded growth. Maintaining consistent humidity levels is crucial for the health of the plant, as fluctuations can cause stress.
To replicate the natural environment of Swiss cheese plants in captivity, it is essential to provide them with adequate humidity. Aim for humidity levels above 50%, and consider using a humidifier or misting the plant occasionally to increase humidity. However, it is important not to overwater the plant, as this can lead to root rot and other issues. The soil should be allowed to dry out slightly between waterings, and proper drainage is crucial to prevent waterlogging.
By understanding the natural environment and requirements of Swiss cheese plants, you can successfully cultivate and care for these beautiful tropical plants, even outside of their native rainforest habitat in Central and South America.

They are mildly toxic to humans and animals
Swiss cheese plants, or Monstera Deliciosa, are native to the rainforests of Central America and South America, where they grow under the canopy of trees. They thrive in bright, indirect sunlight and lots of humidity.
Swiss cheese plants are mildly toxic to humans and animals. All parts of the plant should be considered toxic, although the leaves of some species may contain little to no toxins. The plants contain special cells called idioblasts, which are also found in a number of other poisonous and non-poisonous plant species. Idioblasts differ from neighboring cells in that they contain non-living substances like oil, latex, gum, resin, tannin, pigments, or minerals. One of these substances is raphides, or bundles of needle-like crystals of calcium oxalate that tend to be blunt at one end and sharp at the other. When the leaves, flowers, or stems of the plant are chewed on, the tips of the idioblasts break, allowing saliva or sap to enter the cell. This causes the gelatinous material inside the cell to swell and forces the raphides to shoot out violently from the cell into the surrounding area.
If ingested, the plant can cause serious complications. If the plant is chewed or rubbed on the skin, the crystals can cause a burning and irritating sensation, similar to fiberglass. If you suspect that your pet has ingested part of a Swiss cheese plant, rinse and flush its mouth thoroughly with water. Then, give your pet yogurt, milk, cheese, or any other source of calcium to relieve pain and precipitate the calcium oxalate crystals. In most cases, pets will make a full recovery within 12 to 24 hours of ingestion. However, if your pet is experiencing severe gastrointestinal upset, persistent vomiting, and diarrhea, monitor it carefully for signs of dehydration and provide fluid therapy if needed. If there is obvious oral swelling, it may be advisable to give your pet an antihistamine, such as diphenhydramine (Benadryl). If the airway becomes blocked due to swelling, take your pet to a veterinary office and keep it under observation until its breathing returns to normal.
