old Canadian trick there.........bury there catchs then plant 4-6 month later in the plotsYou can do it in the fall and plant a fish per hole, 2 feet deep. Works better if you can protect the area, like fencing.
It may be different in other places, but putting fish guts in a planting hole around here would be a garanteed fuckup. Coons, skunks , minks would dig the shit up before you got back to the car. Hell, ive never even been able to use simple organics like bone meal, etc.
The black bears around here would smell that from 5 miles away.
