Vermicompost or worm castings are an organic fertilizer "produced" by compost worms... yes, it's worm poop! It contains all the essential nutrients and beneficial microbes for practically ANY plant (indoor or outdoor) and is an amazing fertilizer and soil amendment. You can apply it directly to your plants as a top dressing, or brew them into your own compost tea. When applied to plant foliage, worm castings helps boost the health of diseased and infested plants. Never worry about overfertilizing with worm castings! Unlike conventional fertilizers, worm castings does NOT cause chemical burns with over-fertilization.
The castings were sifted through 1/8 inch screen. There is no foul smell like other animal manure you can purchase commercially, vermicompost smells like earth. The castings may contain worms, worm cocoons, or other composting organisms - all harmless to your plants and are actually beneficial to a healthy soil environment. These creatures only consume and break down "dead" materials. White specks found in the worm castings are ground eggshells added during the vermicomposting process.
