Hi,
I recently bought a blackberry plant (Navaho) and was wondering if any one can help me work out what's going on with it. It has purple edges on all the leaves, one or two have larger purple patches that have started to turn orange.
UK zone 8 if that helps
Editted to include additional info:
I bought it from a garden centre where it was growing undercover but outside. Unfortunately, it's the first time I've bought plants so I didn't check the condition properly, so it may well have been like this before I took it home. It was in a fairly small pot, around 10', and I've since potted it up into a 15' pot
Thanks
