  I moved house 12 months ago and consequently inherited two mahonia bushes each approx. 4 foot tall.  One is green, lush and very healthy looking (situated in semi-shade) whilst the second is lanky, pale green/brown leaves with brown spots appearing (situated in sun for most of the day).  The bark on the stems is gnarled and bearing no leaf shoots apart from at the very top.  It seems to be going worse and I am wondering what I can do to revive it.  Can you please help?   Many thanks           CAROL  HYDE

I'd prune it hard down to about a foot from the ground and then mulch it. Mahonia can take a good hard prune. Mahonia prefers a shaded or semi shaded position so a move will help as well, being in full sun won't help. Keep the roots moist and it may recover.

Agree with Dave - most Mahonia prefer shade and in full sun look quite ugly, exactly as you describe. Cutting it down should revive it. Place it in shade this time and use the sunny spot for other plants.
