cold hardiness of chip buds
In the late summer I chip budded Asian persimmon 'Tam Kam' onto D. virginiana for a friend of mine. They remained dormant, so I expect them to grow in the spring. We're in zone 6, which is the limit for this variety, and I haven't had any dieback on my tree in years past. However, with the cold air coming tonight, I'm wondering if the chip buds are as cold hardy as full branches. Any thoughts on this?
