I DON'T KNOW ABOUT PEANUT BUTTER, BUT A BUDDY OF MINE AND I STARTED MIXING CORN AND DRY, POWDERED STRAWBERRY JELLO. WE USED A POST-HOLE DIGGER AND FILLED THE MIXTURE INTO A HOLE ABOUT TWO FEET DEEP. WE HAVE TO DIG AND FILL NEW HOLES EVERY 2 TO 3 DAYS. I WOULD NOT EVER HAVE BELIEVED IT IF I HADN'T DONE IT MYSELF!
