Awesome People / Awesome Product

I inquired about bulk worm castings for my vegetable garden and Steven replied within the same day. He answered all of the questions I had promptly before I ordered. Whenever it was time to order, Steven was able to help me find the most affordable shipping option. I ordered half a yard and the quality was evident upon delivery. The castings were rich and dark. The only problem I had was that I should’ve ordered more. I’ll definitely order from Brothers Worm Farm every growing season going forward. Great customer service and beautiful castings.
