Hello All! I’m new to Bonsai but have been studying hard and had the pleasure of hearing Jonas speak a couple weeks ago at our San Diego club meeting. I picked up this dwarf river birch yesterday. I grew up looking at one of these outside my bedroom window for more than ten years as a kid and am excited to get it off to a good start.
Since it’s so hot I cut only a few branches that were crossing and likely to cause inverse tapers. I have a few branches coming out of trunk which I consider sacrificial to increase the trunk
thickness. It has a nice main trunk although it’s a bit straight. It’s currently in a 3.5 gal nursery pot. I’m curious about my next year schedule for the tree.
- Should I heavily trim it back in December to define primary and secondary branches?
- Should I replant it in a larger 20gal nursery pot with rich potting soul in February/March to replicate as close as I’m able to field planting?
- should I keep the three trunks to minimize scaring since I’ll already be cutting the sacrificial bottom trunk branches?
- Is it good practice since it’s hot and it’s in pot soil to leave a bit of a nub when cutting a branch at this time of year to accommodate die back and then clean it up in the fall?
Thanks for the help!
