I have had the same problem, have got three bags and was disappointed with the first one so am gonna leave the other two for another few weeks and keep watering them well. Just have to see what happens...! :o)

Hi Dimmlj and welcome to GoY. Have you been watering your potatoes really well and had them in good sunlight? I know GoY members we seems to be able to grow potatoes in bags. We tried last year with little success whilst the ones grown in the ground were fine. If you have space grow them in the ground - easier to do really.

Keep up with the water and give them a bit more time. It worked for me!
