He’s not too far from me, a tad colder possibly as he might have more elevation.
Depends on the year, last year? Early november was barely do-able. No hard frosts, but wet weather in late October sucked. I pulled a few buds off for bud rot before they were finished, I remember that. Some years we’ve had snow in October, so, that might do em in (I HAVE seen pics of some IN the snow that have survived!). Depends on how hard a frost / deep the freeze gets…
