Hedychium greenii - am I too late to head out into the potting shed and dig up the rhizomes of her? it's Feb in Oregon and the day temps are around 35-45. I've had her for 5 plus years, she winters in the potting shed, first bloom was this year. Never cut her down either, she stayed leafed out all year round. What to do? I loved the blooms this year... Help Doreen with tropicals in Oregon Thanks!
If it normally winters in the shed, do you need to dig up the rhizomes? Plus it's almost spring. The article below says this bulb should be separated and planted in early spring, so I would wait till then.

I have a white ginger lily plant that I keep outside in the summer and indoors in the winter. It has gotten so big I can no longer keep it indoors. I live in upstate New York. Can it be planted in the ground and covered for the winter. Will it survive New York state coldness?
I would cut it back rather than plant it outside. You also can cut off all the foliage and overwinter the rhizome to replant in spring. That might keep the size more manageable. Gingers are tropical and can't tolerate temperatures below 50 degrees F.
You are in USDA hardiness zone 5, which is too cold for ginger lilies. If you happened to be in zone 7, the plant might slide by outside with protection. Here is more information:

Gingers are hardy only to zone 7--and even in zone 7 need winter protection. I'm afraid it's not going to survive outside in New York. Perhaps you should divide it this spring and keep a smaller piece to start over with.
Are ginger Lily’s safe for dogs to be around?
Yes, they are not toxic to dogs.

You might have luck with a product containing glyphosate, or a product labeled as a bush killer. It may take a few applications to eradicate all the rhizomes.
