Hi Charles,
I forgot your 2″ depth recommendation , C.D.’s Veg. Course, which of course explains why you can get away with the pull and rummage harvesting method. I might try that next season and see how it works out for me.
I can see from your recent video that I am getting the same harvests from sowing at 6″ as your getting at 2″but have the disadvantage of having to dig the tubers out.
Do you have to do a lot of ridging up as a result of the shallow depth?
Don.
