How to grow potatoes in the bag
Planting sprouting seed potatoes
You will need 60L of Compost and place 40L into the bottom of a potato bag. Position 3 to 5 sprouting seed potatoes on the top of the compost and cover over with 10 – 15cm (4-6inches) of compost.
Keep the compost moist
Water the tubers and keep the compost moist but not saturated. The plants will start to root and shoot, leave them until the shoots and leaves push through the compost layer.
Cover & repeat until the bag is almost full
When this happens cover over the shoots with a new layer of 10cm ( 4inches) of fresh compost. Repeat this process a second time. When the leaves are 20cm above the bag start feeding every 7-10 days.
When flowers show potatoes are ready
When the plants start to flower, usually between 9 and 12 weeks after planting, you can carefully remove the whole plant and the new potatoes and cook them.
