I stop watering my curcumas in October, so mine are going dormant too. Its time to let them go and cut the foliage down so that I don;t have to mess with them anymore this winter!
It's 67 degrees here this morning, and we are looking for what is going to happen with Hurricane Ida. Looks like we are in store for some heavy rain over the next few days. so I guess all that will have to wait.
If it stays warm through November into December, the hedychiums and costus here keep right on going. But all the globbas, zingibers and curcumas are so done for this season.
