This year, with the square foot garden, I told the kids they could each pick a square to plant whatever they wanted. Gavin wanted corn (so we're planting four squares because let's be honest, one square of corn?) and Mackenzie wanted to plant potatoes. We've never tried planting potatoes before and as I researched it, I kind of came to the conclusion that a square foot garden, while it was possible, really wasn't the right place to plant potatoes. I saw so many websites about planting potatoes in buckets or pails, and I thought it sounded pretty easy. So we decided to plant potatoes in buckets. My mom even got on board. As she started researching planting potatoes in buckets, she read some article that said we had to use "food grade" buckets. I'd never heard about "food grade" buckets, but my mom found some at Menards, and I found some at Lowe's, so we are planting in 5-gallon "food grade" buckets.
