How and when should I prune my Black Lace elder as it is shooting fast.
There was a discussion about this a while back - look here http://www.gardenersworld.com/forum/problem-solving/sambucus-black-lace-cutting-back-confusing-advice/1875.html
Hope that's helpful
Following Verdun's advice will be great if you are growing the shrub purely for the foliage - and I know that's Verdun's special enthusiasm - but Sambucus flowers on old wood so if you want the flowers/fruit you should prune after these are over, or only prune a proportion of the stems each year.
I'm interested in the foliage mainly. So have pruned mine last week all in proportion BUT have kept one side old branch for its flowers. Have done this for the last 2 yrs....
I've cut mine to the base and its sending up some lovely dark shoots
