Strategy
See Survival: Day (Hard)/Strategies.

Like all other Survival Mode levels, there are a lot of strategies the player can use that will win. Being a hard level, it has ten flags. The player must use Sunflowers to win and it is helpful to use Pumpkins on a lot of their plants due to the fact that Gargantuars will launch Imps and it's an easy way to stall zombies without using up more lawn space. Gatling Peas and a Torchwood do heavy damage so those are useful. Melon-pults and Winter Melons are also useful because of freezing and splash damage. Keep in mind that the player cannot use helpful aquatic plants like Cattail and Tangle Kelp.
