Winter is almost over now and the grafts look to have survived. It wasn't particularly cold this season with night time temperatures getting to a low of 4deg in the grow room. Some of them are showing some minor marks on the skin and one has slight splitting at the bottom of the stem. I think from over watering.
They are all just starting to wake up and come out of dormancy. I can see new growth on several of them which is a good sign. At the beginning of spring I will post some updated photographs from the winter period, even though not a great deal has changed.
