C. esculenta grows out of doors throughout the year down here in the
South West (Torquay) and survives remarkably well if planted very
deeply (approx 8" deep). In Plymouth, there is a town garden with a
huge A. macrorhiza that has been in the same spot for about 8 years.
Again it was planted deeply, in a sheltered corner close to a wall.
It is given copious amounts of water during summer and given a gallon
of dilute tomato fertiliser every 10/14 days. =20
During frosty weather, the leaves are often killed but the plant soon
recovers with the return of warm, spring weather. Generally speaking,
our summers are not quite warm enough to help repair severe winter
damage, but generally speaking temperatures rarely drop much below 1C
(34F) for more than an hour or so at the dead of winter. So far this
winter despite some pretty chilly weather, my clump of C. esculenta is
still looking fine with only one or two of the oldest leaves appearing
'stressed'. I had planned to lift the tubers and store dry in
newspaper until March, but encouraged by excellent plants in a nearby
garden, I'm going to leave them and if necessary, give a thick mulch
of coarse bark.
Whether either plant could succeed as well further east where sub-zero
temperatures are much more common, remains to be seen.
