## Questions & Answers

**Q: Is this only worm poop and nothing else?**
A: Yes, but so much more. Worm castings are covered in a calcium carbonate slime that, along with a large variety of bacteria, inhabit the worm's gut. As worms 'munch' their way through the soil, their deposits contain 10 times more potassium, 5 times more nitrogen, 7 times more phosphorus, 3 times more magnesium, and 1.5 more calcium and humus than the preexisting soil (in a form plants can easily utilize). Worm castings also contain high amounts of humic acid.

**Q: Can this be used as potting soil?**
A: Typically it's used as the organic matter in potting soil. I make my own.  My mix is 60% coco coir, 20% perlite and 20% worm castings.

**Q: How many pounds would i need to mix 20 5 gallon buckets for my container garden. 20 buckets is just under 14 cubic ft.**
A: I'll tell you what I mix I mix one bag of the worm castings to one bag of potting soil in one brick of Coco coir with two bags perlite mixed all together I hope this helps one bag fills up about 3/4 of a 5 gallon bucket

**Q: Is this something you add instead of fish emulsion as a fertilizer or in conjunction?**
A: Add in conjunction with fish emulsion

I recently started using Wiggle Worm 100% Pure Organic Worm Castings Fertilizer, and let me tell you, this stuff is pure magic. Who knew that worm poop could make plants so happy? Certainly not me! The worms must have had a secret meeting to discuss how to make my plants thrive, because after using this, my garden is practically doing a happy dance. My plants are growing faster than my ability to keep up with the weeding! If you’re skeptical about using worm castings, don’t be. This fertilizer is like a VIP pass to Plant Paradise. It’s the best kept secret in gardening – and it’s all thanks to some very industrious worms. Highly recommended if you want your plants to experience a growth spurt that even your green thumb will envy!
