How to protect Dahlias in Chicago until late Oct?

Hi all,
This is my first year growing dahlias. I'd like to use the flowers for my Oct 8 wedding (as extras in a couple areas). We'll be heading out of town on a honeymoon for 10 days afterwards.
Should I cover them with a hoop house or something similar? I did pvc and plastic sheeting for spring crops, but it might be too short for the 4' dinner plate dahlias. I want to overwinter them indoors, but don't think I can do so before the wedding and keep the flowers fresh (or that I'll have time).
It's already starting to get cold here (high 50s overnight) and I don't know what to do! help!
Thanks

Your Dahlias will be fine unless you actually get a real frost. I have kept mine blooming until mid October here in NW WI. I did build a big plastic tent over them a couple of nights last year, but I dont think it was needed. It was about 40 here last night and they look very happy. You dont over winter whole plants indoors. Cut them down and store the tubers when you finally loose them to a hard frost. You can search this forum for dividing and storing tuber info.

Thanks! Apologies for incorrectly implying that I'd winter the whole plant indoors- that would be a pain indeed!

Do you think Tenting will produce happier plants (aka more flowers) from now until Oct 8? There are a couple of Cafe au Lait Dahlias that are growing, but have no buds on them yet (I planted late). Do you think the added heat will help?
They are all along the East facing wall of my brick garage.
Thanks again.

Pic of White Dahlia including pin sized holes some bug is making. I've seen rice-size & shaped black bugs and cucumber beetles on the flowers. Have yet to see an earwig in the entire garden (even went out with a flashlight at night).

I wouldnt tent unless it is going to freeze. The Pacific NW is Dahlia country, and cool and grey is the norm there. Pretty Dahlia!
