In the first week of August (2013) I started my first attempt at growing potatoes, in grow bags. Actually got the miracle-gro root vegetable bags from garden centre and seed potatoes, so the mix should be ideal.
The seed potatoes are Maris Peers in one and Charlotte's in the other. For Christmas cropping it is advised that you protect against frost, I was wondering if placing the grow bags in something like the Gardman tomato growhouses would be a good idea.
Would the extra warmth throughout the end of the summer be OK? is this likely to offer enough warmth in winter? It should get around 4 hours of sun in mid winter.
Location is East Lothian, Scotland. Just north of the border on the east coast. I believe on the US hardiness scale it is 8b according to trebrown.
