Hi Nanjo, I would think that the cold north easterly winds that we had a few weeks ago have damaged that side of the tree, and the other side has been a little more sheltered, it will probably start to produce leaves later in the year, you can scrape a little bark off with your thumb nail to check if it's still green underneath, if not cut back to where it is still green and wait, Derek.

I would be tempted to wait. It might be die back but it might just be slow at leafing.

Thanks for the advice Derek and Kildermorie, I will bide my time and keep my fingers x :-)

Hope all will be well with your tree.

My Bloodgood has the same problem this year

Wow that is spooky Andrew, let's hope it is only temporary.

Thanks Ladyessex ,I hope so too..:-)
