Ooh Haley Jane! Give them some light and warmth and see if you get eyes/shoots to form. Are you going to plant them in pots for the entire season?

Yes, probably, I have too much stuff out in the garden to remember to dig them up in the fall. I also have some tubers I saved from last year in peat out in the garage. It's funny, I work at a garden center, & we only sell containerized dahlias now, because my boss says people are impatient, they don't want to plant tubers, they want it blooming or ready to bloom now! Of course, we won't get those in for awhile, until it warms up...I did read somewhere about planting them half height in the pot & then adding soil gradually as it sprouts, is this right?

I wish I could forget to dig up in the fall..... Too wet and cold here though.

I don't know that you need to do the half height planting and slow covering with soil in a pot. Pots, and their soil, get more widespread sun exposure and heat up better and dry out faster than garden beds. I had great luck just plunking a tuber in a large pot at full 6 inch depth last year. But in cool, moist spring soil, the slowly-filling-the-hole- method is a good idea out in the garden.
