You can plant them now. Just don't water til they start to come up. Make sure they are in a well draining area. The main problem with most gingers is rot. I have rotted a few. I get over anxious for them to come up and water too much. I have a lot in pots that I take in. This gives them a head start since they are slow coming up. But the hedychiums and some curcuma's you can leave in the ground all year.

I'd say well past last chance of frost... plant them when the night time temps are at least in the 50's... they are tropicals... they prefer it on the warm side

Hi Roy808, I hope your ginger cutting has some rhizome on it, thats the only way I think it can survive. is this the type you are referring too? [IMG]

On a whim, we shoved a sprouted Grocery store piece into the edge of a pot some years ago. We were zone 7a, and let that plant roast on the deck full sun summers, and brought it indoors during winter. When we moved last year, we gave that container to a friend. The hand of ginger in the soil was enormous. I cut off of it once for eating (tasty, we just don't use that much ginger). It didn't bloom, but was probably 4 years old and extremely healthy. Normal soil no thing special, no food, no pests (and there were pests everywhere, believe me). Died back indoors every winter (we let it "rest"). Came rebounding crazy each summer. Pot was probably 14" across at the top cheapo plastic. Try it. Good luck!
