SteveM Fascinating! And thanks for the photo of your setup too. I do have plants of the same variety in separate locations, but I havenβt dug up too many this year. Now that we are looking at some below freezing temps, Iβm regretting that, but Iβve got pot tubers as backups.
That said, once itβs digging weather again, Iβll be interested to see how the tubers near the streetlight compare.
Thanks!
