Rainbow Farms Mealworm Fertilizer
Approved by Organic Gardening Magazine

     After many years of recommending Bone and Blood Meal, the folks at Rodale Press (Organic Gardening Magazine) reversed their position and now no longer recommend or advise growers to use blends that contain Bone Meal, Blood Meal or commercial steer and chicken manure. Over past years there has been an increasing number of transmitted diseases to garden soil from the toxins often used; antibiotics, growth hormones and steroids. "Not worth the potential health problem, even if it's only a small chance. There are plenty of vegetative sources without having to use animal sources." – Michael G. Fertilizer expert, Extension Institution.

"Rainbow Farms mealworm castings however, are probably "organic" in the true sense of the word. It is not comprised of elements containing contaminates and is pure mealworm castings and not a blend. Anything else that comes from animal byproducts is suspect and I would not use them." -Michael G. Extension Institution

Hi Joe,
Your logo is certainly eye-catching! Thanks so much for sending the information on your product – I have passed it along to Doug Hall, our Garden Editor. I think our readers would respond well to your product, so I am copying Jessica Siegel.  Your mealworms must be happy campers from the great food you feed them.
