I grow sweet potatoes in 40 litre bags and, so far, the yield has benn abysmal. Don’t try unless you relish a challenge and have time and space to spare.
Three difficulties are lack of hot summers, short seasons and critters that come and get the crop before you can.
This year I’ve overwintered some cuttings and plants(last years with crop removed then re-potted) to allow maximum growing time. (Bought slips sent out in May are too late imoh.) They started to look sad at year end but perked up under lights alongside overwintered tomatoes. Incidentally, I left one flower on a Rosada which has now developed into a surprisingly ripe fruit.
All I need now is a long hot summer and some wire netting – not much to ask for….
