All my potatoes have been nuked by Potato Blight. Have removed haulms and will leave ground for 3 weeks for spores to die. I believe my father used to lime the soil after he had lifted all the spuds after a Potato Blight raid, though I seem to remember him talk about Bordeaux mixture which I would prefer not to use. Has anyone else limed the soil after the dreaded P/Blight? Also should I sow a green manure after the spuds are all up and then lime in the early Spring or is it better to lime immediately after the spuds are lifted?
I only grow organically and make much use of companion planting and preventive planting
