Grave Buster Strategy
A Grave Buster removes Graves and Zombie Gravestones, letting the player plant more plants in the level where the graves once were. These are available after beating Level 2-3.
To use a Grave Buster, plant it on top of the grave you want removed. A Grave Buster takes about 4.5 seconds to destroy a grave and can be eaten by zombies while doing this.
Try to remove the leftmost graves first when using a Grave Buster, since that frees up more squares on lawn for plants to attack zombies and gives them more time to deal damage.
