Garden post Ophelia

My Dahlias and Rudbeckia have all been knocked to the ground. I will have to cut them all back now as I would have done after 1st frost. Will this have adverse effect on next year's blooms. Also should I lift and store the dahlia tubers now or leave them until frost arrives?. I'm sure you will get many similar questions over next few days.

Even though knocked over, plants that are still green continue to photosynthesise and build up reserves for next year. 

But you can leave them until frost, or lift and store, if you wish, as there is only a few weeks left in any case.  Growth continues until the soil temperature falls to 6 Celsius after a few frosts.
