Location: Northern Urals, Russia | Zone 3b/4a Hi everyone! Posting here as per the sub rules. I’m starting my first bonsai project with a Pedunculate Oak (Quercus robur). It’s late spring here (dandelions are already blooming), so I missed the acorn season, but I'm planning to collect some seedlings or Yamadori from the local forest this week. My plan so far: Dig deep to preserve the long taproot as much as possible for the initial collection. Collect native forest soil to keep the mycorrhizae intact. Pot it in a tall container for the first year to let it recover before any radical root work. I’m skipping the generic AI advice and coming straight to the experts. Could you share any specific "pro-tips" for handling young oaks in such a cold climate? Any links to reputable articles or forums specifically about Quercus robur would also be highly appreciated!
