Monstera obliqua
Swiss cheese plant · Broken Heart Plant
Description
Source: leafsnapMonstera obliqua is a species of the genus Monstera native to Central and South America. It is hemiepiphytic like most other Monstera species. The plant is particularly known for its foliage, which is often highly perforated, sometimes described as having more empty space than leaf. An illustration of the general variation in adult leaf shape from different individuals of this species can be found in Michael Madison's 'A Revision of Monstera'. The species is not commonly cultivated, but the name is often misapplied to specimens of the more widespread Monstera adansonii.
💡 The Swiss cheese vine is valued for its intriguing and unique foliage, characterized by perforated leaves. This distinctive pattern is known as fenestration and becomes pronounced as the leaves mature. The formation of the holes is due to cells either dying or stopping their development in the leaves. The size and shape of these holes vary between different species.
🌳 Monstera obliqua is not only visually attractive but also functions as a natural air purifier. This lesser-known ability comes from its capacity to absorb pollutants through its leaves. Additionally, although not widely recognized, Monstera obliqua has been used in indigenous practices to craft durable, attractive natural jewelry, supporting sustainable fashion. The plant’s striking leaf patterns have also inspired artists, giving rise to botanical prints and textiles. In fact, Monstera obliqua holds potential across various industries because of its unique physical characteristics and symbolism.

Care Guide
💧 Water Every week
Monstera obliqua is native to tropical rainforests, where it thrives in high humidity and moist soil. To maintain its lush growth, it prefers balanced moisture levels and typically needs to be watered weekly. When grown indoors, it's essential to keep the soil consistently moist to ensure the health of its evergreen foliage throughout the year.
How should I water my Monstera obliqua plant in the best way?
There are many ways to water your Monstera obliqua plant. If you have it in a small indoor pot, you can easily bring it to your kitchen sink and use the faucet to add water until it starts to drain out of the pot's holes. Just be careful not to do this during winter or in cold climates, as it can harm the roots. If your tap water has high levels of fluorine, chlorine, or salts, it's better to use rainwater or lake water. Additionally, you can also water the plant by using a watering can, hose, or any other tool you prefer, as the Monstera obliqua responds well to overhead watering and direct soil watering.
What should I do if I give my Monstera obliqua too much water or too little water?
If you realize that your Monstera obliqua is not getting enough water, the first thing you should do is water it thoroughly until water is coming out of the drainage hole or until the soil is completely moist if it is grown outside. On the other hand, if you notice that your Monstera obliqua is getting too much water, start by watering it less frequently. It's also important to consider the type of soil and container it is planted in. If the soil or container prevents efficient drainage, your plant may become overwatered again. To solve this problem, you can replant your Monstera obliqua in looser soil or a container with larger drainage holes or a more porous material. Additionally, check the location of your plant. If it is in a corner or a place with poor ventilation, it is advisable to move it to a window or a more ventilated area. Having your plants in a well-ventilated location can help prevent overwatering to a certain extent.
How often should I water my Monstera obliqua plant?
The Monstera obliqua is a plant that does not need consistent soil moisture. Instead, it's best to let the soil dry out between waterings. If you're growing Monstera obliquas in containers, you can tell if it's time to water by checking how dry the soil is in the container. If about half of the soil is dry, it's time to water. You can feel the dryness by sticking your fingers or a stick into the soil, or you can use a soil moisture meter. If you grow the Monstera obliqua outdoors, plan to water it about once every other week, as long as it hasn't rained recently.
How often should I water my Monstera obliqua?
To water your Monstera obliqua, wait until the top half of the soil is dry. Then, add enough water to make the soil moist again. The amount of water needed depends on the size of your plant and container. For a small Monstera obliqua in a small to medium-sized container, one to two cups of water should be enough. For larger plants, increase the amount of water accordingly. To ensure your plant is properly watered, you can check the moisture level by sticking your finger or a trowel into the soil. Alternatively, water until you see excess water draining from the bottom of the container.
How can I know if I'm giving enough water to my Monstera obliqua plant?
Both overwatering and underwatering are detrimental to the health of your Monstera obliqua. However, they exhibit distinct symptoms. Insufficient watering can lead to yellow leaves and brown, fragile leaf margins. On the other hand, overwatering often results in yellow and brown marks appearing simultaneously on the leaves. In addition, overwatering can facilitate the development of diseases like root rot, which may be visible on your plant. Fortunately, if you are familiar with the signs of overwatering and underwatering, there is a high likelihood of successfully addressing these issues.
☀️ Light Full shade
The monstera obliqua grows best in places where it isn't fully exposed to sunlight, although it can tolerate occasional hours of gentle sun.

🌱 Fertilizer
Monstera obliqua will need the most fertilizer during its active growth phase, which takes place mainly in spring, summer, and early fall. Fertilizing provides essential nutrients the soil may lack, supporting healthy root and stem development and encouraging the attractive foliage that is a key feature of this plant.
Why should I use fertilizer on my Monstera obliqua?
All plants, including the Monstera obliqua, need soil nutrients to grow. However, it's not always guaranteed that the soil will have all the necessary nutrients. That's why fertilization and soil amendments are important. They help ensure that your garden plants have not only the basic nutrients they need, but also the specific nutrients necessary for their growth. In particular, the Monstera obliqua needs fertilizer to support the healthy development of its roots, stems, and leaves. Fertilization will contribute to a beautiful set of leaves, which is especially important as the foliage is the main attractive feature of this plant.
When should I fertilize my Monstera obliqua?
A Monstera obliqua requires the most fertilizer when it is actively growing, which usually happens during spring, summer, and early fall. After winter, feed your Monstera obliqua every two to four weeks until fall. As fall approaches, gradually decrease the amount of fertilizer given until you stop completely in preparation for the less active growth in winter.
When is it not a good idea to fertilize my Monstera obliqua plant?
For most of the year, including spring, summer, and most of autumn, it is important to regularly feed your Monstera obliqua. However, there are a couple of exceptions to this. If you notice that your plant has received too much fertilizer or has been fertilized incorrectly, resulting in fertilizer burn or another issue, you will need to address that before resuming the regular feeding schedule. Additionally, it is important not to fertilize your Monstera obliqua during winter. If you keep this plant indoors in a cold winter environment, it will go into a dormant phase during this time. Feeding the plant during dormancy is not only unnecessary and unhelpful for its growth, but it is also likely to cause fertilizer burn.
