-Citron with PF -Grapeshot, but you need to position it right on the Gar. as the bouncing grapes that all (or mostly hit) will finish it off

This seems to confirm this list... http://plantsvszombies.wikia.com/wiki/Grapeshot "Notably, a Grapeshot under the right circumstance can instantly vanquish a full health Gargantuar (besides a Jurassic Gargantuar), a feat that can otherwise only be achieved by Electric Blueberry and Citron's Plant Food effect." Explode-O-Nut doesn't OHKO a Garg, it explodes like Cherry Bomb which only does 90 NDS. Gargs generally have 180, so it's a two shot.

The full list afaik is Electric Blueberry, Citron (via PF), Grapeshot if placed directly on top of a garg, Caulipower, and Witch Hazel.
