Yesterday I noticed that one of my Sebago plants had quite suddenly gone all yellow. There was only one plant left in that bag (the others having been lost to rot), and I figured as it had gone all yellow it wasn't going to be doing any more producing. I didn't have great expectations, to be honest.
I got a surprise.
A modest, but encouraging first harvest, and I have another five bags of robust-looking plants still growing heartily away.
So, I now have an empty potato bag. I've never tried growing sweet potatoes in bags, but it could be time to plant out these little slips I've had growing on the windowsill. Let the sweet potato experiment begin!
