Victrinia,

If this tree came from the collection I think it did(95% sure), I cannot give you more specifics at this time. The previous owner is quite ill, and it would be too presumtious of me to question him about trees right now, as he has other priorities. I do have 3 of this cultivar(2 in the ground, 1 in a pot). When healthy, they are vigorous vase-shaped growers. They tolerate(and may actually benefit from) more direct sun than other Acer Palm of the palmate group. Their light & soil requirements more closely parallel the dissectum group-(ie: slightly more sun, slightly drier soil...or better drainage...BUT NEVER PARCHED). As far as the deadwood, I wouldn't leave it, particularly with our wet weather. Deadwood and the inevitable resulting rot, on deciduous trees(especially maple), is like a cancer that will spread. I know('cause I used to feel the same way) you will feel like you are cutting away some of the structure of the tree, that even the dead wood has aesthetic value. You're better off to face the music, you have already lost that structure, and it won't come back. I'd remove the bulk of it now, waiting to cut into live tissue 'til Spring. Then cut to live tissue & treat to encourage healing. I realize you are proud of this tree(and should be), but IMHO it's not ready for a final pot. The desired lateral & surface root-growth will be easier to achieve with a wooden grow-box. You're right to eliminate the Mica pot... a wooden box will hold much less summer heat(from direct sun) than either the mica or a ceramic pot. Don't over-pot too much though, you only want to give your "trimmed root-mass" an additional 1-2 inches on the sides and 1/2 inch underneath. Then give the roots a year or two to colonize that. Postpone your final pot selection for several years 'till you've worked out your styling plans both above AND below the soil-line. You ultimately will be happier. These get their fall colors later than most, but not to worry. Get ready for a beautiful yellow-gold flushed with crimson fall coloration from the end of October to middle November.
