I purchased these because they do not contain dairy, soy or corn.  Well, in addition to being dairy free, soy free.... they are FLAVOR FREE!  Absolutely horrible dry tasting bars.  First words out of my mouth were "tastes like dirt" so that's what I'm going with.  DO NOT WASTE YOUR MONEY.

Husband and Grandaughter LOVE this cocoa... Make it for them all the time as I drink my coffee.. My husband is a very picky person but for some reason he really likes this one product and wants me to keep it in stock here at the house.. Loves it at night after dinner on cold evenings.

Works wonderfully for most all applications in the garden. Could not be easier since it is systemic and helps fertilize only what you want to fertilize.
