Before they have sprouted and rooted, I water sparingly just to keep the medium moist. However, once rooted and sprouted, I pot them up, give them a good watering, and then water as I would a normal plant with roots and top growth.

Actually, I took yesterday off from potting, and this morning I have more to do. 'Gotta go now and do it.

I still have not done the ones still in the refrigerator! Since I'm out of pots, I thought of spreading out potting mix in a shallow tray, laying them out, then watering just to get them to sprout a bit before planting out in about 2 weeks. Would this work? I've heard of the baggie trick too, but think I could be neater in a tray. This has to go where my DH will see it, and he complains about messy things.

I do have space on top of the frig in the garage: will the warmth really help them to sprout?

Last fall was my first time dividing, and I could not see any eyes. So I imagine lots of my divisions are eyeless and useless.

Linnea, you could do the tray, but if you're unsure on eyes on your divisions, I'm swearing by the baggie thing. Tubers I was ready to give up on for good have sprouted in their little plastic greenhouses. I find I prefer good potting soil in the bags as opposed to one with lots of peat- soil stays damper longer. I am also finding that I have to add moisture every couple days because those babies are cooking in south windows and the soil dries out quickly.

Just try a couple for a little dahlia experiment. Hands down, it's the best dahlia thing I've learned in recent memory. If your husband wants neat, you could neatly line a boot box or shoe box (or ten) with baggies in a bright window. Heat from a refrigerator would likely help. I like to give them light though too. Nothing like sunshine.... which is outside now and therefore I return to digging.
