Is it too early to cut back dahlias?

I am pushed for time for the next week or so, would it be ok to just dig out my dahlias and leave them sit on the surface for a few days? I am hoping to dig them out on a drier day and if I dont do it now no doubt when I have more time the heavens will have opened up.

 

Even the experts get hot under the collar about this Scudo so you will get a different view to mine ...that's fine
However, I have recently been cutting down my dahlias just as I have always done. They do not suffer a jot.
I do so for a number of reasons......one is I want to allow space for the emerging plants like hellebores and daffodils.....daffodils are already growing strongly. ....I can access them to mulch etc. Cutting them back, even though they still have plenty of flowers is a job done. I can also divide them and pot up. Waiting for frost to "seal" them etc., means I could be waiting for another couple of months here
I would not leave them on the surface though....I would turn them upside down and put in gh, cold frame or cover with a cloche or sheet of glass. The important thing is to dry them out before over wintering.
