You are doing it wrong. Here’s what fertilizer to use on what houseplants

Houseplants have exploded in popularity over the last decade, but many people are unknowingly harming their leafy companions with well-intentioned—but misguided—fertilizer choices. Just because something is “natural” doesn’t mean it’s right for every plant. In fact, using the wrong type of fertilizer can lead to root rot, pest infestations, or nutrient imbalances that slowly kill your plant. And while you might feel like you’re giving your plants a little love, you could actually be stressing them out.
