Peace Lily: Can One Ingredient Really Make It Bloom for 10 Years?

Coffee grounds are frequently recommended online as a miracle fertilizer.

Fresh coffee grounds are not an ideal universal fertilizer for indoor plants.

Used coffee grounds contain organic material and some nutrients, but simply piling them onto the surface of a houseplant’s pot isn’t a reliable fertilization strategy.

They can also contribute to moisture retention and other problems when used excessively.

If you enjoy composting coffee grounds, incorporating them properly into compost is generally more sensible than using thick layers directly on a houseplant.
