Sambuca nigra.

My Sambuca  that is 3 years old and is planted in an enormous pot hasn't flowered for the past 2 years.  I prune it right down as advised in late February.  Plenty of new leaf growth but once again no sign of any flowers forming.  Any advice please.

Do you feed it at all, and give it plenty of water? Mine were pruned mid February and started flowering about a week ago, but they are in the ground, which is really much better for them if you can find a space.

If you prune all the shoots down each year you wont get flowers as they flower on the previous year's growth..
The trick is to prune a few down to the ground and prune a few a bit less and you'll get flowers on them.
It's what I do with mine

Jenny.  I do keep it well watered and feed tomato food weekly.  Cant put it in the ground as I dont have much space.  
Pete 8.  I will follow your pruning advice and keep my fingers crossed for next year.
Many thanks to you both  !

The usual method is to prune back approx 1/3 of the stems back to the ground each spring then cut back some of the older stems to different heights then you get flowers from top to bottom. The new growth that pops up will give flowers for the following year.
It wont need weekly feeding, probably once or twice a month while it's growing will be enough

Err.... mine are cut back quite hard every spring and they flower on the new growth (they are the variety Black Lace).

Pete.8 I've just posted a problem with my black lace and lack of flowers this year. Yours look lovely on this thread and I'm hoping the experts can give me a solution to the problem.
