Hilling potatoes is one of those debatable practices. I've done it. Many people claim it "needs" to be done. It is conventional wisdom for sure. However, there are those who argue that it only robs the plant of energy that would be used to produce tubers and is completely unnecessary. I'm not arguing either way. I'm simply testing out this planter with some neglected seeds LOL I'm really hoping that the deep pockets and planter containers on this Greenstalk garden will be suitable to hold lots of potatoes! It's all a fun experiment 😎
