When you add another tire, cover it with soil. Keep the top four or five leaves poking out and continue to grow your potatoes in this manner (keep adding tires and soil) until they reach maturity!

Harvesting potatoes is a laborious process, but the rewards are well worth it.

First, you have to remove any yellow leaves from your plant and then carefully take out each tire until all soil has been removed from around them, so they can dry completely before they’re ready to be consumed.
