help with karma dahlia culture - new to dahlias

I don't know what I was thinking, but I have a number of karma dahlias coming my way via mail order and I'm not certain if I have enough sunny space.
Here are my varieties: Dahlia Karma Choc - Dahlia Karma Bon Bini - Dahlia Karma Fuchsiana - Dahlia Karma Lagoon� - Dahlia Karma Corona� Red - Dahlia Karma Corona� - 3 of the chocolate and 2 of each of the rest. Here are my questions:
- How close together can these be planted
- Can I pot some up, and if so, exactly how big a pot do I need to use
- In the PNW - will 6 hours of sun be enough - will they bloom with less?
- Is there a way to protect the tuber from MOLES/VOLES - my two biggest garden pests next to deer
-Does anyone in zone 8 - portland, oregon area leave the tuber in the ground or must they be removed in the fall
Can someone point me to dahlia FAQs -
- any additional advice for one completely new to dahlias, but experienced with gardening and thankfully have good dirt!!

Eight hours of sunlight is best, without it the plants will be tall and spindly and the blooms will be sparse and weak.
You can definitely pot some of them up, here is a great article about growing dahlias in containers

Thank you - good link!

My next question - the tubers are in plastic bags with wood shavings. SHould I leave the bags closed or open them. It is still too early to plant here - I'm thinking the first of May. Can the tubers hold in the plastic bags?

Those are wonderful dahlias. They stay very compact and don't get tall and spindly. I can't remember if I even pinched them but to keep them compact, pinch them anyway. You have plenty of sun for them. I feel for you with the Voles. I lost all my clematis. They just tunneled down and ate the whole thing. It had taken 3 years for them to cover the arbor and now nothing. I have tried everything with the voles but my dahlias are in raised beds. I have never had voles there. Good luck.
