How to Fertilize Monstera
When Should I Start Feeding My Monstera?
Since Monstera is almost always grown indoors, feeding timing follows seasonal light levels more than your local frost dates.
How Often Should I Fertilize My Monstera?
Feed every two weeks during spring and summer when your Monstera is actively pushing out new leaves. This is when it's hungriest and can actually use the nutrients you're giving it.
Once early fall arrives, cut back to once a month at half strength. By late fall, stop feeding entirely. Winter light levels are too low for Monstera to grow much, and unused fertilizer just builds up as salt in the soil.
If you notice brown leaf tips or a white crust on the soil surface, you're probably over-fertilizing. Pale new leaves or slow growth in summer can mean it needs more.
What Is the Best Fertilizer for Monstera?
Monstera is a foliage plant, so it needs a fertilizer with a bit more nitrogen than phosphorus or potassium. A 3-1-2 ratio (like 9-3-6) is ideal because nitrogen fuels the big leaf growth Monstera is known for.
A liquid fertilizer is the easiest option. It distributes evenly through the soil and lets you control the strength each time you feed. Dilute to half the label rate to avoid burning the roots.
Slow-release granules can work too, but they make it harder to taper off in fall. Stick with liquid if you want full control over your feeding schedule.
