Thank you all for the honest opinions and advice. I hate to throw this tree out. How would I make it into an informal upright or other style. I am going to leave it alone as suggested but when the time comes I would like to do what is best for the tree. I will get another and try again I guess sometime. The wind is gone from my sails on this one. I just want to save it now
I think we probably all started by over-pruning something - don't sweat it. It's a completely normal part of the learning curve. It takes a few iterations before you start to get a sense for how they grow and what you should keep and what you should chop. If it's any consolation, I moderate a fairly large bonsai forum over on reddit, and I see pictures of butchered trees all the time.
For next time:
- Work junipers slowly. Set an initial direction, then leave them along to recover.
- Shorten branches, don't remove them
- Don't remove more than 25-30% of the foliage at once. Then give them at least a year to recover.
- Low branches are your friend. Even if you're not sure how you might use them, keep them anyway.
- Junipers do back bud over time, but you need to leave them alone and let them do it.
- The wire you used isn't thick enough for the branches it's on. You want to add movement on those branches closer to the trunk. 1/3 the thickness of the branch for aluminum wire and 1/4 the thickness of the branch for copper.
- With junipers especially, I like to think in terms of 3-5 year blocks of time, not 1-2 year blocks. No rush.
- Once you're certain this is healthy, you can chase the foliage back by
slowly by shortening the branches a bit and then waiting for new growth to come in
- As new growth comes in lower on the tree, leave it alone
If this one survives the process and the winter, it will likely fill back in, but it could easily take 3-4 years. If it doesn't make it, chock it up to a learning experience. We all kill trees sometimes. I've probably killed more trees over the years than most people will ever own.
I generally recommend that people get at least 2-3 trees to start in any case so that no one tree gets too much attention. No need to throw this away - you'll learn from watching it grow back in if nothing else.
Good luck!
I purchased a Juniper at my local nursery. I am a beginner and I have been doing a lot of reading and looking a photos of other juniper bonsai. The one that I purchased was very over grown and root bound. I like a challenge I guess. This is what I cam up with after pruning today. I would like advice on where to go from here. I have done a little wiring to get the trunks to stand up and lean to one direction. I would like it to all flow and turn out some what nice. Suggestions other that toss it and start over are welcome
