Strategy
The Winter Melon is one of the most useful auto-fire plants in the game, but the best plant in terms of instant damage is the Cob Cannon, while the Gloom-shroom is at the top of the list in terms of overall DPS (damage per second) output. The Winter Melon is an upgrade of the Melon-pult, although the attacking rate is half times that of a Peashooter, and the same as a Melon-pult, but it can freeze zombies within a half-square radius, and the damage, despite what it says in the almanac, is the same as that of a normal Melon-pult (heavy). A single Winter Melon is strong enough to kill a Gargantuar by itself, partly due to the slowing effect. The Melon-pult and Snow Pea combo has a similar effect, but the Snow Pea can only affect one zombie at a time.

Survival Mode
The Winter Melon is very useful in Survival Mode, especiallly Survival: Hard or Endless, because there are lots of zombies and the splash damage will be very useful. Also, strong zombies such as Football Zombies or Giga-Gargantuars often appear, so with a few Winter Melons they'll will make it much more easier to kill them.

Trivia

 * Winter Melons inflict higher damage than Melon-pults on unarmored zombies, but the splash damage is normal.
 * When the Winter Melon recharges and has enough Sun, but you don't have any Melon-pult on the lawn, a message will appear saying "Plant a Winter Melon first" instead of "Plant a Melon-pult first" which the latter should be correct.
 * It is the one of the two Upgrade Plants that cost less Sun than the plants they upgrade; the other plant is the Gold Magnet.
 * The Winter Melon, the Ice-shroom and the Snow Pea are the only plants with icicles on them, and the only plants capable of slowing zombies.
 * The Winter Melon is a vegetable while his downgrade's name, the Melon, comes from a fruit.
 * If a zombie is in front of a Winter Melon, the zombie will instantly be hit by the Winter Melon's frozen melon like other Catapult Plants and their projectiles.
 * There's actually a fruit with that same name [1].
 * The Almanac mentioned that the Winter Melon had projectile with a very heavy damage. But actually, it does the same damage with that of the Melon-pult (4 normal damage shots per melon). This is probably because of its faster shooting speed and its slowing efects on a zombie giving it more time to attack the zombie.
 * The Winter Melon has one achievement related to him, Melon-y Lane.
