He told me he'd grown it from slips or cuttings and this is how he did it: he tied the cuttings in bundles with string. Then he made planting holes where the soil was good and put down a thick layer of oats . . . the kind you give to horses, though he said porridge oatmeal would do as well. Then he put the bundles of cuttings into the oats and left them to overwinter. In spring, they had all developed fantastically strong roots, which still had some oats clinging to them. These are what I will now call forever 'A Cavanman's Cuttings'.
