I've had 4 hebes in pots for about a year and they've gone very brown and twiggy underneath with black spots on the outer leaves which have stayed green. When I cut one of the stems it's still green so I think they are still alive, is there anything I can do to save them?
I've taken them out of the pots and put them in larger ones in the shade as they got a lot of sun where they were. The soil was very dry but I thought that hebes don't like too much water. I'd quite like to plant them in the ground, but thinking that might not be a good idea in this heat. Should I just keep in pots in a shady spot for now and start occasionally until the autumn, then stick them in the ground and hope for the best?
