Not only does growing potatoes in a barrel reduce the amount of weeding and exposure to pests and fungi, you don't even have to risk shovel-damage to the tender potatoes by digging them out of the ground when they're done, just tip the container over! Earlier in the season you can very carefully slide your hand into the soil and check to see what's growing, even harvest a few baby potatoes without doing any harm, the rest will continue growing. When the time comes to give up working a large kitchen garden the container will become your best friend. Joyce's recommendations
