Does anyone else on this ng know or grow this Cut-leaf Lilac? I have had
mine for several years now and, despite feeding it with high potash food
and, once or twice, starving it in case that helped, there has never
been so much as a flower bud. I know it is capable of flowering because,
in desperation, I've looked on Google Images. That just makes it worse,
because I know how gorgeous it can look :~{

It is now growing in a large pot (it has been potted on over the years
as it's grown, but certainly never over-potted). I could pot it on again
or leave it in it's 15" pot. Maybe restricting the rootball would help?
I would *love* to see it flower (each year preferably), but I'm
beginning to wonder if I'm wasting my time.

Can anyone offer me any advice or hope?
Thank you.

Do you prune it? And if so when?



No, not really, except to snip off damaged ends after winter. It
doesn't seem to need any more pruning than that.
