What You'll Learn

Swiss cheese plants thrive in bright, indirect sunlight
Swiss cheese plants, or Monstera adansonii, are native to the jungle floors of South America. They are known for their large, heart-shaped leaves that develop holes as the plant matures, resembling Swiss cheese. This process is called "fenestration" and allows light to pass through to the lower shoots of the plant.
As a tropical plant, Swiss cheese plants thrive in bright, indirect sunlight. Place them in a warm spot, such as near a south-facing or west-facing window, where they can receive ample light without direct exposure to harsh rays. If indirect light is not available, bright morning sunlight is preferable to afternoon sunlight, as the afternoon light can be too intense and cause damage. You can also add a sheer curtain to a west-facing window to filter the light and create the desired indirect lighting conditions.
The amount of light a Swiss cheese plant receives is crucial to its growth and distinctive appearance. If the plant does not receive enough light, its leaves may not develop the characteristic holes, and its growth may be stunted. On the other hand, too much direct sunlight can scorch the leaves and cause harm. Therefore, it is essential to find a balance by providing bright, indirect light for optimal growth and the development of the unique fenestrations.
To ensure your Swiss cheese plant receives adequate light, you can place it near a window that receives indirect sunlight or provide a source of artificial light if natural light is limited. By creating the right lighting conditions, you can promote the growth and distinctive features that make Swiss cheese plants so appealing.

They need moderate temperatures of 18-27°C (64-81°F)
The Swiss cheese plant, or Monstera adansonii, is a low-maintenance houseplant with distinctive holes and notches on its heart-shaped leaves. It is a tropical climbing plant that is native to the jungle floors of South America.
Swiss cheese plants require moderate temperatures of 18-27°C (64-81°F). They thrive in warm, humid environments that mimic their native tropical habitat. Maintaining a consistent temperature is important, as sudden drops or drafts can stress the plant. Aim to keep your plant in a room that is comfortable for you, as both you and your plant will be happy with moderate temperatures.
If your plant is exposed to temperatures below 64°F (18°C) for too long, its growth may slow down and it could eventually die. To prevent this, avoid placing your Swiss cheese plant in areas that are too cold, such as near a drafty window or an air conditioner.
You can create a warm environment for your Swiss cheese plant by placing it in a bright, indirect light spot, such as near a south-facing or west-facing window. Just be sure to avoid direct sunlight, as it can be too harsh for the plant.
In addition to moderate temperatures, Swiss cheese plants require high humidity levels of 60-80%. If the indoor air is dry, you can increase humidity by placing a water tray or a humidifier near the plant or by misting its leaves occasionally.

They don't need frequent watering
Swiss cheese plants (Monstera adansonii) are low-maintenance plants that do not require frequent watering. They are native to the jungle floors of South America, where they receive plenty of humidity from the environment. Therefore, when kept as houseplants, they require higher humidity levels, preferably between 60% and 80%.
To maintain the right humidity levels for your Swiss cheese plant, you can place a water tray or a humidifier near the plant. Alternatively, you can mist the leaves occasionally. It is important to note that tap water containing fluoride or chlorine should be avoided. Additionally, make sure that the plant is not placed in a location with direct or hot sunlight, as this can cause the leaves to scorch. Bright, indirect sunlight or partial shade light is ideal.
When it comes to watering, Swiss cheese plants should be watered no more than once a week, allowing the topsoil to dry out completely before watering again. The frequency of watering may vary depending on the environmental conditions, so it is essential to monitor the soil's moisture level regularly. During the growing season, typically in spring and summer, you may need to water more frequently. However, during the dormant period in fall and winter, reduce the watering to once every 7-10 days.
Overwatering can lead to root rot, so it is crucial to ensure proper soil drainage and avoid waterlogged soil. The soil should be kept moist but not soaked. A well-draining terracotta container can help regulate moisture levels. Additionally, the presence of aerial roots on the Swiss cheese plant indicates that it is seeking moisture from the air. If you water your plant regularly, these roots will not need to absorb water, and you can trim them without causing harm to the plant.

They grow well in a moss-covered pole for support
Swiss cheese plants, or Monstera deliciosa, are known for their large, heart-shaped leaves that develop holes as the plant matures, resembling Swiss cheese. They are tropical vines that require support as they grow. In the wild, they use aerial roots to climb up rainforest trees in Mexico and Central America. When grown as houseplants, they can be supported by a moss-covered pole.
A moss pole is a solid structure, usually covered in sphagnum moss, that provides a surface for the plant's aerial roots to penetrate and attach to. The moss also provides moisture and micronutrients, helping the plant grow tall and healthy. It is important to keep the moss moist without oversaturating it. This can be done by dripping water down the length of the pole or using a spray bottle when the moss starts to feel dry.
To add a moss pole to your Swiss cheese plant, you can purchase one from specialty plant nurseries or create your own by covering a pole with moss. Place the pole in the soil near your plant and use soft, foam-coated plant wire to guide the stems towards the pole. The plant will climb the pole if it wants to, and the support will help it grow upwards rather than out.
Using a moss pole for your Swiss cheese plant is a great way to provide the necessary support for healthy growth while also adding an exotic touch and tropical vibe to your indoor space. It mimics the plant's natural habitat, allowing it to climb and thrive. With the right care, your Swiss cheese plant will develop its distinctive large leaves with unique holes, creating a beautiful and impressive houseplant.
