Soil Your Plants is an achievement unlockable on the Xbox Live, PSN, and PS Vita versions of Plants vs. Zombies. It requires the player to plant ten Peashooters. This achievement can be easily achieved by playing the first few levels in Adventure Mode.
It might be a reference to some Plants vs. Zombies trailers, which contained the tagline "Get ready to soil your plants!"
- In the trailer for the Xbox 360 version, it shows this achievement being unlocked in Versus Mode.
