do you have wheat hay or wheat straw? hay is a green cut plant left to dry in the sun and I do not know of farmers cutting the wheat for hay. straw is the wheat that has been harvested once it is mature and has turned brown. the grain separated from the shaft via combining it and the left over shaft is used for straw.
wheat, oats, barley and rye can be used as straw and any left over grain will sprout in the garden. we have used rye before and its a total pain to till under. farmers actually spray it with roundup to kill it off then till it under and it helps to then release the weed killing benefits of it.
