I've just received a pack of 25 Sambucus nigra 'Aurea'
from a hedging company. I've split some with other
allotmenteers. the plants are 2' high and are just
showing signs of budding. The question we're asking is
when and what to prune.

There seems to be some conflicting information on the
net. Some suggest cutting down to ground level in early
Spring. Another states that you should cut new growth
by half, but remove this growth down to ground level,
the following year. I'd like to keep the row, to a
maximum height of 4'. Any tips would be appreciated.
Thanks
Bertie
