I have had the devil of a time with my labrador, Thelma, and the asparagus bed: every time I lay down chicken manure (well mature and dry...from a bag) she comes along...later when i am not looking...and she eats it. There is nothing better to her than some good old chickenpoop. Almost as good as Avocados!
Well...put a layer of Coffee Grounds on that chickenpoop and it goes untouched!!!! I tell you...it is GREAT! This is a dog that eats anything and everything...yes, oranges and broccoli...and she leaves the chickenpoop untouched when covered with coffee grounds...and it doesn't even have to be a solid coverage!!!!!
