Answer 1

Answer:

Organic Worm Castings are the rich digested soil that red wiggler worms leave behind. Savvy gardeners know them to be chock-full of organic plant food, plus beneficial microbes that aid plant growth and help fight off disease. In addition, castings contain humic acid which aids plant nutrient absorption.
