Sapling
I have these 2 Tridents I'd like to attempt approach/thread grafting. I live in the San Francisco bay area (Mtn. View climate zone 9B). Seen a number of articles and still wondering the best time to attempt this, thread grafting in particular. Is it best to thread graft before the buds swell or later in the season after cutting off the leaves? The buds are quite large now so I'm leaning towards grafting later because sap is flowing and the dormant buds, at the trimmed leaf nodes can be threaded through a smaller hole. What would be the best time of the year for approach grafting? Is one method preferred over the other depending on tree age?
