Strategy
Because of how cheap they are, they can be very effective early in levels. After that, the long arming delay makes them difficult to use, try putting them at least 4 squares before the zombie. This is enough for a zombie that travels at the same speed as the normal zombie.

Placing a Potato Mine behind a wall plant (Wall-nut, Tall-nut, or Pumpkin) can maximize its effectiveness; when the zombies break the wall, (assuming there are no faster zombies such as the Jack-in-the-Box Zombie, Flag Zombie, etc), they will all be within the explosion range of the Potato mine when the first one reaches it. They can also be planted behind Wall-nuts or Pumpkins to catch any Pole Vaulting zombies that try to vault over them. Similarly, they can be planted to make a Pole Vaulter jump early, in addition to catching later zombies.

Potato Mines are also effective against Digger Zombies. When they try to dig under an active Potato Mine, it will explode. Spudow!

Surprisingly, Potato Mines actually can be used against Gargantuars, but you probably won't end up doing so. It is extremely effective against Zombie Bobsled Teams, killing the bobsled along with all four zombies if armed and planted by the ice.

In ZomBotany and ZomBotany 2, Potato Mines cannot be hit by peas, even when armed.

In addition to planting Potato Mines in a row with zombies, you can put a Garlic to force zombies onto a Potato Mine.

In Column Like You See 'Em, Potato Mines are useful for Gargantuars when you're out of Jalapenos. If Ladder Zombies put their ladder on the Tall-nuts, immediately plant the Jalapeno. When a Jalapeno hits a Gargantuar, and they've smashed the Tall-nuts, Potato Mines are the plants you need. When armed, Before Gargantuars smash the plant, they explode, thus killing the Giant Zombie.

Potato Mines can be placed inside of a pumpkin and once armed any zombie attempting to eat the pumpkin will surprisingly set off the Potato Mine
