I loved that you're growing potato's in a bag. I had tons of reusable bags in my closet so decided rather then plant my large tomato plants in the raised bed, I would instead fill the bags 3/4 with store- bought garden soil and plant them in those bags and line them up along the fence so, when the plants reach their large size, I can tie them upright to the fence.
So far, so good they have already grown taller then the top of the bag and have only been in them since Friday. This is my experiment for the year with gardening and I do love all you're doing in your garden.
