Worm castings are a superfood for plants - think nitrogen, minerals, and humic acid which helps your plant absorb nutrients much more efficiently. A little of these goes a long way, but don't worry - they're totally organic, so you can't hurt your plants by using too much.
You can sprinkle this on top of soil or mix it in when repotting. We recommend this fertilizer for all plants, indoor and out!
