hi,
Fu suggested me to post my question in a thread so more can read.
Q: I found the leaves are a bit yellow and with some black spots recently, did i make sth wrong?
A: The Hebe is going to go to poo in the winter, they always do and always will. They show up in garden centres for cheap prices and in numbers each Autumn and late summer because the wholesale growers don't want to have them in stock through winter because they get frost damage and go yellow and crappy. It's normal
the Hebe is feeling the cold and the metabolism is slowing down. Lower leaves on the hebe will be shed and the green ones higher will go yellow and get black spots. When the warm nights return, they will green up .
So if u have the same problem, u don't need to worry too much.
Thanks Fu
