Not all the potatoes we have planted have gone into the ground. We kept back 30 seed potatoes to plant in bags. See the picture above. These were specially purchased for the purpose and should be long lasting.
We got two sizes. The large size, in the above photo, can be planted with 5 seed potatoes. The small ones can have one each. I took the small ones to London to use in our garden there.
As with the furrows, in the early growing period, as the shoots grow, add more compost. The above bags were planted 2 weeks before we planted the others into the ground.
These bags are ideal if you have a backyard or a balcony. They can be used to grow other vegetables as well. I will be planting out the spares shortly in London with carrots.
