Is This a Monstera? A Gardener's Guide to Identification and Care
"Identifying and caring for your new green friend."



Unveiling the Mystery Plant: Is It a Monstera?
Bringing home a new plant is always exciting, especially when its identity remains a delightful mystery. You might find yourself staring at its leaves, comparing it to your other green companions, and wondering, “What exactly are you?” This is a common experience, and today, we’ll delve into the world of houseplants, focusing on a plant that often sparks this very question: the Monstera.
The Allure of the Monstera
Monsteras, with their iconic split leaves (fenestrations), have become incredibly popular in recent years. Their striking appearance makes them a statement piece in any indoor space. But, before you get ahead of yourself, let’s address the question at hand.
The Pothos Connection: Similarities and Differences
Your initial thought of a pothos is a good starting point! Both Monsteras and pothos plants are vining plants that can add a touch of the jungle to your home. However, they are distinct species. While pothos are known for their heart-shaped leaves, Monsteras are famous for their large, often hole-filled, leaves.
If your mystery plant’s leaves are more substantial and less heart-shaped, with a thicker, sturdier appearance, it could very well be a Monstera. But, let’s look at the potential plant a bit closer.
Key Features for Monstera Identification
- Leaf Shape and Size: Juvenile Monstera leaves may not have the iconic splits. However, they are generally much larger and more leathery than those of a pothos, even when young. As the plant matures, the splits (fenestrations) and holes (leaf perforations) will become more pronounced.
- Stem and Growth Habit: Monsteras typically have thick stems, and they grow in a climbing or trailing manner. They often produce aerial roots that help them climb and absorb moisture.
- Leaf Texture: Feel the leaves. Monstera leaves are generally thicker and more substantial than those of a pothos, which tend to be thinner and more delicate.
Common Monstera Varieties
If your plant is a Monstera, knowing the different types can be fun. Here are a few popular varieties:
- Monstera deliciosa: The most common type, known for its large, split leaves. This is the classic Monstera.
- Monstera adansonii: Often called the “Swiss Cheese Vine,” this variety has smaller leaves with numerous holes. It’s a beautiful trailing plant.
- Monstera dubia: This is a unique variety that, in its juvenile form, has small, heart-shaped leaves that grow flat against a surface. As it matures, it develops fenestrations.
Is Your Plant Sick? Spotting and Addressing Leaf Issues
One of the most important aspects of plant ownership is understanding potential health issues. Let’s address the spots on your new plant’s leaves, which is a valid concern.
Identifying the Problem
Leaf spots can be caused by various factors. The most common causes are:
- Fungal Infections: These often appear as circular or irregular spots, sometimes with a yellow halo. They can spread if not addressed.
- Bacterial Infections: These spots can look water-soaked or have a greasy appearance. They can also spread quickly.
- Pest Infestations: Tiny pests, such as spider mites or mealybugs, can cause stippling or discoloration on the leaves.
- Environmental Stress: Improper watering, inconsistent temperatures, or insufficient light can also cause spots or discoloration.
Steps to Take
- Isolate the Plant: Place your new plant away from your other plants. This prevents the potential spread of any disease or pests.
- Examine the Spots: Carefully examine the spots. Note their color, shape, and distribution. This will help you narrow down the cause.
- Check for Pests: Inspect the leaves, stems, and undersides of the leaves for any signs of pests. Use a magnifying glass if necessary.
- Assess the Environment: Consider your plant’s environment. Is it getting enough light? Are you watering it correctly? (More on that below).
- Clean the Leaves: Gently wipe the leaves with a damp cloth to remove any dust or debris. This can help you get a better look at the spots and potentially remove some pests or fungal spores.
Treatment Options
The treatment you choose will depend on the cause of the spots:
- Fungal Infections: Treat with a fungicide specifically designed for houseplants. Follow the instructions carefully.
- Bacterial Infections: Bacterial infections can be more difficult to treat. Remove severely affected leaves. Improve air circulation around the plant, and consider using a copper-based fungicide.
- Pest Infestations: Treat with insecticidal soap or neem oil. Repeat the treatment as directed on the product label. Ensure you cover all parts of the plant, including the undersides of the leaves.
- Environmental Stress: Adjust your watering and lighting practices to better suit your plant’s needs. Research the specific care requirements for your plant.
Monstera Care: Essential Tips for a Thriving Plant
Whether or not your mystery plant turns out to be a Monstera, here’s a guide to caring for these beautiful plants:
Light
- Bright, Indirect Light: Monsteras thrive in bright, indirect light. Avoid direct sunlight, which can scorch the leaves. An east-facing or north-facing window is usually ideal.
- Signs of Insufficient Light: If your Monstera isn’t getting enough light, the leaves may not develop fenestrations (splits). The plant may also have slow growth and smaller leaves.
Watering
- Allow the Soil to Dry: Water your Monstera when the top inch or two of soil is dry to the touch. Overwatering is a common problem that can lead to root rot.
- Water Thoroughly: When you water, do so until water drains from the drainage holes. Discard any excess water that collects in the saucer.
- Signs of Overwatering: Yellowing leaves, droopy leaves, and soft, mushy stems can indicate overwatering.
- Signs of Underwatering: Dry, crispy leaves can indicate underwatering.
Humidity
- Moderate to High Humidity: Monsteras appreciate moderate to high humidity. If your home is dry, you can increase humidity by:
- Using a humidifier.
- Placing the plant on a pebble tray filled with water (make sure the pot isn’t sitting in the water).
- Grouping plants together.
- Signs of Low Humidity: Brown leaf tips can indicate low humidity.
Soil
- Well-Draining Soil: Use a well-draining potting mix. A mix designed for aroids (plants like Monsteras and pothos) is often a good choice.
- Avoid Compacted Soil: Compacted soil can retain too much water and lead to root rot.
Temperature
- Warm Temperatures: Monsteras prefer temperatures between 65-85°F (18-29°C).
- Avoid Cold Drafts: Protect your plant from cold drafts from windows or doors.
Support
- Provide Support: As your Monstera grows, it will benefit from support. You can use:
- A moss pole: This mimics the natural environment of the Monstera.
- A trellis: This provides a structure for the plant to climb.
- A stake: This provides basic support.
Fertilizing
- Fertilize During the Growing Season: Feed your Monstera with a balanced liquid fertilizer diluted to half strength during the growing season (spring and summer).
- Reduce Fertilizing in Winter: Reduce or stop fertilizing during the winter months when the plant’s growth slows down.
The Joy of Plant Parenthood
Whether your new plant is a Monstera or not, the experience of nurturing a plant is rewarding. Be patient, observe your plant closely, and adjust your care practices as needed. The joy of watching your plant grow and thrive is one of the greatest rewards of plant parenthood.
