These potato towers made outta tires worked out pretty good. It wasn’t our first choice for making potato towers but, when the tires were free and you’re crunched for time… we just had to give it a try. We pulled only 1 tire off 1 tower to check on them because we have never grown potatoes this way. We got about 20 really nice spuds and saw that there were many more tiny potatoes still left on the plants. So we replanted them back into the tower, which is now only 2 tires high to see if we can get some more red potatoes out of these plants.
