    I really love adding Crab meal (the crushed shells) to my soil mix. A very natural pest KILLER, research chiton , amazing stuff. I amend my soil mixes with Crab meal and neem for a sense of insect defense with the added benefit of a natural NPK.

    I recently ordered this product to help add chitin to my soil, both garden & potted houseplants which have summered outdoors. I am hoping it will deter any “hitchhikers” from wintering in my house. I’ll let you know how it works on the house plants later.

    This stuff is pure gold! Every time I top-dress with it, I see a visible spurt in growth. Even more important is the CHITIN! I got a couple sick plants this season which were drooping close to death. This disease spread to a few nearby plants. When I fed crab meal to these sick plants all indications of disease stopped immediately. Even the sick-unto-death plants not only revived, but are HUGE! I will never be without it.
