Tip-When planting the Potato Mine, remember that you need at least three squares of distance for the mine to be ready. It will kill the zombie and allow you to still plant a Sunflower in the last row spot. Tip- If a zombie is walking in your lawn with no Sunflower in your last square, instead of planting a Sunflower there and then a Peashooter in front of it, plant a Potato Mine. The Potato Mine is a great option as it only costs 25 suns but does an enormous amount of damage to any zombie that crosses its path. One important thing to remember is that you want to be frugal with your suns. There are various plants, nuts, and even vegetables that will help you in this endeavor. The best strategy is to set up Wall-Nuts to slow it down, use multiple Peashooters, or use the Squash to kill it in one move. It can take 5x more damage than a normal zombie. Buckethead Zombie- Don't let the bucket fool you this zombie is tough to bring down.
