Finally I wired the thing a second time. A couple of weeks ago I showed it after the wire came off and I had throughly edited the crown. Someone critisized me for having taken of too much. I admit it looked like it. But now one can see that with my kind of styling the crown looks like it has enough foliage again. I think it does not need much more in the future. Now the wire will stay on another three years. And then we'll see. The last image is a virtual showing the same pot by Peter Krebs, only much smaller. Maybe next spring I will find the smaller pot for it.
European spruce, Picea abies, collected by peter Thali in in Switzerland 2001, around 100 years old, pot by Peter Krebs, 30 cm high.
