Okay, folks, let’s talk about fertilizing indoor plants in winter. I’ve got a bunch of houseplants, and figuring out the winter feeding schedule used to be a real headache. Here’s how I tackled it, and what I’ve learned along the way.
My Winter Fertilizing Journey
First off, I started by looking at my plants. Really looking. I mean, are they actively growing? Pushing out new leaves? If they are, they might need a little something. If they’re just chilling, looking the same as they did a month ago, they’re probably dormant.

I noticed that my Peace Lily was still putting out new leaves, even in December. My Snake Plant, on the other hand? Not a single thing. So, the Peace Lily was a maybe, the Snake Plant was a definite no.
Figuring Out What to Use
Next, I had to decide what fertilizer to use. I’ve always used a liquid fertilizer, the kind you mix with water. I’ve got a general-purpose one that’s worked well for me in the past.
I’ve found that a balanced fertilizer, you know, with equal parts nitrogen, phosphorus, and potassium which is showed on the label as N-P-K, that get my plants really good.
The Dilution Experiment
Here’s the key: I diluted the heck out of it. The instructions on the bottle? I cut that in half. Seriously. Winter light is weaker, so plants aren’t photosynthesizing as much. They don’t need a full-strength dose.
- Step 1: Read the fertilizer label (duh!).
- Step 2: Mix up the fertilizer solution at HALF the recommended strength.
- Step 3: Water the plants that are actively growing lightly with the diluted fertilizer.
Watering and Observing
I watered my actively growing plants with the diluted fertilizer, making sure not to overdo it. I figured less is more in winter. Soggy soil is a recipe for root rot.
Then, I watched. I checked the soil moisture regularly. If it was still damp, I held off on watering again. I looked for any signs of fertilizer burn – brown leaf tips, usually. Luckily, I didn’t see any.
The Results (So Far!)
So, it’s been a few weeks, and my Peace Lily is still looking happy, putting out a new leaf here and there. My Snake Plant is still just hanging out, which is exactly what I expected. My other plants also looks good.

The big takeaway? I learned that winter fertilizing is all about moderation and observation. Pay attention to your plants, dilute your fertilizer, and don’t overwater. It’s not rocket science, just a bit of common sense and a willingness to experiment (carefully!).
