Robinia pseudoacacia 'Frisia' has an anoying habit of dying back, or
even dying altogether. It can be pruned heavily but you should be
aware that after they reach 15 years or so they tend to become
unstable, with frequent troubles around the base. We've lost about 6
or 8 in the last few years and are expecting to lose the rest over the
next few years. We don't plant them any more because of this.


Is it die off of the roots, or stem rot causing this as I haven't noticed
any problems with our tree and it's well over 15 years old. However it's not
"Frisia" but "Tortuosa" with normal coloured leaves.
At least mine flowers well, I've never seen a Frisia flower yet.
Do they flower?
