Hi Guys,
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.
many thanks
Paul

Too much Nitrogen probably. Try giving it some Rose fertiliser in early Spring and then nothing else.
The leaf problem sounds like one of the leaf spot fungus to which almost every plant is host. Remove the damaged leaves first of all and see it if returns.
