Lmfao talk about making life difficult! Why would u use those stupid things u gott best to death with a hammer only to turn em into smaller pieces that will never disintegrate from your soil when u could just use the bits and topdress couple tablespoons easy peasy? Dunks are made to go into pools of standing water like ponds or birdbaths/ fountains whereas the bits are pretty much ready to go and not the consistency of powdered drywall!
