Can anyone recommend new potato varieties that will cope with fairly heavy clay soil, are slug resistant and have some blight resistance. My allotment is close to the boundary hedge which appears to harbour the world's supply of slugs and blight seems to be getting earlier every year on our site. Also, does the old trick of putting wood ash in the potato trench work? Our fire only burns wood so I assume it will not add any nasty chemicals. Should I leave the trench open with the ash in it to weather before I plant or just go for it?
Thanks for any advice anyone can offer.
Sue
