Digging potatoes from our yard for our Thanksgiving meal started by mistake. A few years ago a section of our yard turned into a jungle. It was November and after the usual 3 week stretch of non stop rain, the patch was quickly turning into a yellow mushy mess. I'll admit it. . . it was an eyesore. Armed with yard waste bucket and shovels we marched outside during a rain free moment. Imagine our surprise while pulling up plants we discovered potato gold below the surface. Those glorious potato volunteers! Now the kids were engaged! A treasure hunt.
Every year since we designate a spot in the garden or flower bed and plant potatoes. Water them a bit and then ignore them. That is our motto. Then, right before Thanksgiving we all march outside and start digging around for our potato treasures.
