Four tiles with Dave's mold colonies on them

Dave's mold colonies are green chunks of mold in Plants vs. Zombies 2 that appear on certain tiles. They only appear in levels where one of the requirements is to not plant on them. They are environment modifiers. In the current version, it is impossible to plant on them so they cannot directly cause the loss of a level. However, before the 1.7 update, they could be planted on, which would result in the loss of a star from planting of them.

  • In earlier versions, plants which multiply themselves under Plant Food (such as Potato Mine and Chili Bean) could land on a mold colony and not disable the objective.
    • In newer versions, it is impossible for them to land on a mold colony. If there is no room left on the lawn other than on mold colonies, they simply will not spawn.
  • When the player completes a level with them, the mold colonies will start jumping. The player will hear a squishing sound while the mold colonies are doing so.
  • The mold colonies will hide if the player hovers a plant above them.
  • In earlier versions, planting on mold colonies would make them splat.
  • In some Lost City levels with Turquoise Skull Zombies, the game may have used the mold colonies as a trap to make the player plant closer to the zombies, so when Turquoise Skull Zombies appear, it will make it easier for them to burn the player's plants.
