Nick it’s a question of how much I can mention in an hour! I could easily speak for three hours and still only touch on many subjects.
Maincrops run into blight in August, so are more risky.
Yes you can pull compost around them, or drop a shovelful on top of plants if tubers are pushing up into the light.
Sarpo varieties resist blight but need harvesting by early September for better flavour, not too late.
