I need some advice.
I bought at the end of the season a Kolkwitzia (beauty bush) I've had one before in my garden and had an abundance of bloom in may /June.
This one however I put in a large patio pot and initially fed it the occasional growmore liquid.
In three years it has grown bigger, in full leaf, but never, ever flowers!..........Why? the leaves incidentally alys have a brown stain on them that covers half the leaf, I would love to have this flower, so what am I doing wroing?
Your help would be much appreciated.
