When you buy a Monstera, it often comes planted in heavy, dense potting soil. While this works initially, it's a disaster waiting to happen. The number one killer of Monstera plants is root rot, caused by poor drainage.
To prevent this and encourage giant, beautiful leaves, you need to ditch the basic bag of soil and create a special "chunky" aroid mix that mimics its natural climbing habitat.1
🥣 1. The Perfect Chunky Soil Recipe
In the wild, Monstera are hemiepiphytes, meaning they climb trees and root in the light, airy debris that collects in branches.2 Your mix must reflect this need for excellent drainage and aeration.
Here is a recommended starting recipe for your Monstera soil blend:
Component | Purpose | Recommended Ratio |
Indoor Potting Soil | Base, nutrients, water retention. | 40% |
Orchid Bark/Coco Coir Chips | Creates essential air pockets; mimics jungle bark structure. | 30% |
Perlite or Pumice | Prevents compaction and improves rapid drainage. | 20% |
Worm Castings/Activated Charcoal | Natural slow-release nutrients; helps filter impurities. | 10% |
Why This Mix Works:
Aeration: The chunky bits (bark, perlite) ensure there is plenty of oxygen flowing around the roots. Without oxygen, the roots suffocate and rot.
Rapid Drainage: When you water, the moisture is released quickly, preventing the soil from becoming heavy and waterlogged.
Longevity: This mix breaks down slower than standard soil, meaning you don't need to repot as frequently to refresh the structure.
🍽️ 2. Feeding Your Monster
Monstera are vigorous, fast-growing plants during the warmer months, and creating those giant, fenestrated leaves requires energy. They are considered heavy feeders.
What to Feed
Use a balanced liquid fertilizer with an even or slightly higher nitrogen (N) ratio (e.g., 10-10-10 or 20-20-20 diluted). Nitrogen promotes lush, green leaf growth.3
When to Feed
Growing Season: Fertilize every 2 to 4 weeks throughout the spring and summer (your plant's active growing period).4
Dormancy: Stop feeding completely during the fall and winter months. The plant's metabolism slows down, and fertilizer salts can build up in the soil and burn the dormant roots.
The Golden Feeding Rule
🚨 Never fertilize a dry plant. Always water your Monstera thoroughly first, and then apply the fertilizer solution (diluted according to the bottle's instructions). Applying fertilizer to dry roots can cause severe chemical burn.5
🔑 Soil Moisture vs. Humidity
A common beginner mistake is confusing the need for high humidity with the need for wet soil.
High Humidity (Air): Your Monstera loves having moisture in the air (use misting or a humidifier).
Dry Top Soil (Roots): Your Monstera needs the top layers of its root ball to dry out between waterings to stay healthy.
By focusing on a chunky, aerated soil mix, you solve the number one problem and set your plant up for magnificent, hole-filled growth! All the best.
