This image came up during a search ('trident+maple+shohin') and Walter's entire blog can be seen here. It is well worth bookmarking, as there is too much high-quality content here to view in a single sitting.
I recall a lengthy discussion at bonsaiTALK a year or so ago in which Mr Pall was one of a very small minority who insisted that there was no need to treat the deadwood of deciduous trees with lime sulphur. From memory, his argument was that deciduous trees rot out in nature, and that a healthy tree should not be at risk from rot. When others cited cases of trees in the wild which had 'succumbed' to rot (and, by extension, to disease(?)), the discussion turned to the theory that such trees had failed structurally and not physiologically. That is, that the rot had removed/weakened so much heartwood that the sapwood shell was no longer able to support the tree, in which case it would collapse. In Bonsai practice, a healthy Trident Maple should put on more sapwood in a year than rot could take away, thus collapse is a non-issue. (At least that is what I think I got from the discussion - it was a long time ago.)MelaQuin wrote:Lime sulphur is good stuff.
I cannot comment on the timing of the deadwooding process on my Trident: the damage to the lower trunk was wholly unintentional, and it occurred during the height of Summer when the bark suffered a nasty case of sunburn. (That said, the deadwood work I am doing on my Pyrus was started in Spring last year and I have seen no ill-effects: if anything, the bark is advancing and not receding.)anttal63 wrote:DO NOT DO NOW!
winter when the tree is dormant or you will get die back.
Anyway, there's some food for thought. I look forward to seeing how you progress with these great little Tridents!
Fly.
i will be waiting a couple of weeks before i prepare the area for a hardener and protection, just because there was a few minor nicks to the cambium layer, these need to heal first.
