i've searched on here for a topic covering this but haven't seen one. i noticed the other day that some of my potatoes that are in potato bags have got a bit of black on them, then someone told me today that this is prob due to the frost the other night. now, are the plants bu''ered? they have only been got a touch on a few leaves, and have kind of gone crispy and i've nipped the bad bits off. will they survive? they dont seem too badly got, just tinged a bit.
If you haven't lost most of the leaves they will recover quite quickly.
;D
