@Frank: They look very tasty. I bought my Marseilles black labeled like that, no vs, so I don't think that I have the same strain. We will see in a season or two lol
@Mike: I started after the last mini cold snap of a few hours of 29°. I cut the leaves that were frost damaged or just damaged by nature etc before that point. I have noticed that leaves that are damaged are first to be dropped by a tree if it is stressed in any way followed by those that are "imperfect"/blemished. This way my actions follow normal patterns. I also double checked to make sure that no buds were trying to reform, and pinched the few that attempted. About 5 days later the first leaf stems of the cut leaves began to fall and I cut the remaining leaves, a few of which were already looking blemished. I wanted the trees to go dormant as naturally as possible while minimizing stress, knowing full well that my cold temps drop too fast when they do and a fully natural cycle was out if the question. Only one of my larger trees was 90℅ dormant, even with 40° weather and many nights hovering 32-34°, most barely had lost any leaves. I suspect that my cooler summers made the cool fall seem less drastic but have no way of knowing for certain. Perhaps I am over thinking things, but I want the trees to conserve energy before dormancy and recognize environmental weather stress, without stressing the trees out. I know from experience that they attempt to hold onto their leaves as long as possible. And even sacrificing wood to do so. This is obviously undesirable. (This has happened when the cutting makes insufficient roots and in attempt to sustain leaves drains the cutting) I would let them brave colder temps but this season they got a bit if a late start and their branch tips still have a bit of green on most. I double checked pinching buds so they don't "freak out" from leaf loss and try to grow a new one, which a few tried to do. Hopefully my energy conservation efforts will be rewarded by a massive spring growth flush ;)
@pitangadiego It is true that you live in a state with 0℅ chance of rain and high heat, so snow is a bit if a myth!
