natural shading by plants

I have a birch myself, I think they are great, they are among my favorite trees. They just live.

If you want your [Fächerahorn] and can buy exactly that (where do you get that?!), then go ahead.

And even if you manage to train them halfway properly, you still have to continue pruning and caring for them. Unnatural growth forms always require maintenance.

I also like birches visually, but they produce such an enormous pollen mess that I really wouldn’t plant them near a seating area...

Yes, that's true, I wouldn't either. For me, with the birch and the others, it was just about the fact that there is more than just different maples that you can train like that and that are still heat- and drought-resistant. I think when it comes to leaf drop, maple is a good choice, but I also find beech interesting here, because it often still has its leaves in winter, so it's not so bare.

I don't have an alternative planting ready either, as our garden planning is finished. I just wanted to point that out.

In this respect, I'm looking forward to a new picture with the new trees

I am aware of the pruning. However, I think the workload is manageable with 4 trees and a good pruning shear. I prefer a tree that loses its leaves in winter, since otherwise little light comes through the corner window. Of course, there will be new pictures as soon as everything is finished.

Here we go!
