Is ther a potato I can grow in the SE england that will be ready for christmas?
Well yes there is so why not grow your own potatoes in a either in grow bag or large container. They will be ready for christmas if you plant them about the beginning of November. Jusy buy a bag of tatties and let them chit. To do this you put them on a tray in dark place and cover with newsparer turning them gently once a week taking care not to damage the shoots. It usually takes about 10 days to a forthnight to chit properly…so this will be about the middle of October you need to start chitting them. Then plant them in good compost or soil about 4 inches deep and then as soon as the shoots start coming through you cover the shoots with soil so as stop them from going green you do this until the shoots push through again. Once the shoots have flowered and the leaves start to wilt then you can harvest them and Voila! You have lovely new tatties for Christmas and New Year. I would try and get hold of either King Edwards; Maris Piper or Charlotte potatoes for chitting.
