Can someone identify this shrub please and tell me what I can do to help it - I couldn't find a section for Shrubs specifically. It's part of a small hedge comprised of Heather, Skimmia and something with a variegated leaf I don't recognize. The entire hedge was very overgrown with brambles until recently. Since being cut back and brambles removed it's apparently now decided to die . It's been watered and we've also had rain. No idea why this is happening. Can I save it??
