I found a solid Dawn Redwood (metasequoia glyptostroboides) at a local nursery but before I pulled the trigger on it I was wondering about timing for trunk chop?
My assumption is either late spring after new growth hardens off or to wait until the foliage turns color in autumn then chop it? Does it make a difference with a deciduous conifer?
Other option is to airlayer it, do they take to airlayers?
If so, then would it best to keep it in a recovery box/grow bag until a new leader establishes to 70% percent of the final thickness?
Also with the quality of akadama being hit or miss for me, I was thinking a 3:1:1 (is this the right logic) or what mixes have people had success with
As always thanks for any insights and help!
