The Monstera deliciosa, also known as the Swiss cheese plant, is famous for its lush foliage and dramatic fenestrations. Many indoor plant enthusiasts admire the enormous, split leaves that make the Monstera such a statement plant. But getting those large, iconic leaves indoors doesn’t happen by chance. It takes the right environment, consistent care, and a few tricks that mimic the plant’s natural jungle habitat.
If you’re wondering why your Monstera still has small, solid leaves while others have massive, mature ones with elegant holes and splits, this guide is for you. Here are five proven tricks that will help your Monstera grow the giant leaves it was born to produce.
Give It the Right Light
Lighting is the most important factor when it comes to growing big Monstera leaves indoors. In the wild, Monsteras climb tall trees in rainforests and thrive in dappled sunlight. Indoors, that translates to bright, indirect light.
While Monstera can survive in low light, it won’t thrive or produce large, fenestrated leaves in those conditions. Small leaves and slow growth are often the first signs your plant isn’t getting enough light.
Place your Monstera near a north or east-facing window where it receives several hours of bright, indirect sunlight every day. If your space is dim, consider using a full-spectrum grow light. Keep in mind that too much direct sun can scorch the leaves, so aim for filtered light rather than harsh rays.
A well-lit Monstera will not only grow faster but will also be more likely to produce mature leaves with the dramatic splits and holes you’re hoping for.
Let It Climb
One of the biggest secrets to growing giant Monstera leaves is allowing the plant to grow vertically. In nature, Monsteras are climbers. They use aerial roots to latch onto tree trunks and grow upward toward the light. This upward growth triggers the development of larger leaves and encourages fenestrations.
You can mimic this natural behavior by providing a sturdy support, such as a moss pole, coco coir pole, or trellis. As the Monstera climbs, it will begin to develop stronger stems and larger foliage.
Tie the stems gently to the support as they grow, encouraging the plant to attach with its aerial roots. Over time, your Monstera will begin to mimic its natural growing habit and reward you with those larger-than-life leaves.
Water Consistently, But Don’t Overdo It
Watering is a balancing act. Too little water and your Monstera may become dehydrated, causing slow growth and dry edges on the leaves. Too much water, and you risk root rot — a condition that can stunt growth or kill the plant entirely.
The goal is to keep the soil consistently moist but not soggy. Let the top inch or two of soil dry out before watering again. During the growing season (spring and summer), your plant may need more frequent watering, while in the cooler months, you’ll want to scale back.
Always check the soil before watering, and use a well-draining potting mix to prevent water from pooling at the bottom of the pot. A mix of potting soil, perlite, and orchid bark works well to support both moisture retention and drainage.
Watering consistency encourages steady growth, which is key for producing those iconic large leaves.
Feed It During the Growing Season
Like most houseplants, Monstera benefits from regular feeding, especially during its active growing season — typically from early spring through late summer. Without proper nutrients, the plant may grow slowly or produce smaller, less dramatic leaves.
Use a balanced liquid fertilizer (such as a 20-20-20 or similar formula) once a month during the growing season. If you prefer organic options, a diluted fish emulsion or worm castings tea can also be effective.
Be cautious not to over-fertilize. Too much can cause salt buildup in the soil, which can damage the roots. Always follow the instructions on your fertilizer, and flush the soil with water every few months to wash away excess salts.
A well-fed Monstera is more likely to grow vigorously, which is essential for achieving those large, mature leaves.
Increase Humidity and Maintain Warm Temperatures
Monsteras are tropical plants, and they thrive in warm, humid environments. One reason why Monsteras grow such massive leaves in the wild is because of the high humidity levels found in rainforests.
Indoors, low humidity can hinder your Monstera’s growth and lead to dry, crispy leaf edges. To mimic the tropical environment, aim to keep the humidity level above 50%, though 60–70% is even better if you want dramatic leaf growth.
You can increase humidity by:
- Using a humidifier near the plant
- Grouping plants together (they release moisture into the air)
- Placing a pebble tray with water under the pot
- Occasionally misting the leaves (though this is more for aesthetics than actual humidity)
In addition to humidity, temperature plays a big role. Monsteras prefer temperatures between 65°F and 85°F (18°C to 29°C). Avoid placing your plant near drafts, cold windows, or air conditioning vents. Consistent warmth helps the plant grow strong, lush, and ready to unfurl its next giant leaf.
Final Thoughts
Growing large Monstera leaves indoors is absolutely achievable it just takes a little know-how and consistency. Start by giving your plant plenty of indirect light, let it climb like it would in the wild, water it wisely, feed it regularly during the growing season, and recreate a warm, humid atmosphere.
Remember that patience is key. Monsteras don’t grow giant leaves overnight. With time, care, and the right environment, your plant will reward you with lush, tropical foliage that turns heads and brings the jungle vibe right into your living room.
Give your Monstera the attention it deserves, and those iconic, oversized leaves will be well within reach.
