Melon-y Lane

Difficulty: Very Hard (Easy if Survial Levels) (Extemely Easy if Last Stand)

This can be achieved easily in the Survival Levels, especially in Survival: Endless and Survival: Roof, Last Stand and all three-wave Day levels.

Strategy
Playing Last Stand can let you get this Achievements since you have enough sun to plant 6 Winter Melons but you must put 1 in each lane. To speed up the process in any other level, simply place a lot of Sunflowers and Imitater Sunflowers.

It's usually not a good idea to attempt this achievement in a shorter level (like the first level) because the Winter Melon takes a very long time to recharge.

In Last Stand, some strategies involve putting a Winter Melon on every lane.

Note: It is advised to do this on a Day, Night or Roof level as there are only 5 lanes.

Note: You do not need to complete the level to get this achievement, meaning that you can get this only planting Winter Melons in Last Stand, then quitting.

Trivia

 * You can get this achievement without keeping the Winter Melons alive.
 * You can't get this achievement on the GotY edition.
 * This is a reference to melody lane.
