How to grow potatoes in a bag

Roll the sides of the potato bag down so it’s just under a third of its usual height. Add 10cm peat-free compost to the bottom of the bag and place three to five chitted potatoes on the surface. Cover with another 8-10cm of compost and water well. When the shoots have grown to around 8cm, ‘earth them up’ by covering them with another 10cm of compost. Do this every couple of weeks, gradually rolling the bag back up to its intended height. This stops the potatoes from being exposed to light and developing green patches.
