Sambucus nigra 'Aurea' golden elder not budging
I bought a Sambucus nigra 'Aurea' (golden elder) at the same time as buying a Sambucus Nigra Black Lace.
The black lace is in the worst position of the two (quite shady under a tree) and has flowered and grown to about 5ft but the golden one has done nothing.
It is still only inches high and just does nothing.
I'm starting to think that I need to take it out and give the ground a good dig - wondering if there's a brick or layer of concrete under it or something?
