Dhalias still flowering late November
Hi I need a bit of advice please. My dhalias are still blooming - all be it smaller flower heads, but as we are now having our first frosts, should i cut them off and dig them up for the winter? I have always hated cutting flowers off in bloom, and they are bringing a little bit of colour. I am concerned that if I leave them to die down they will use up all their energy and not flower so great next year - any advice would be great.
