    I have a plant of Thunia bensoniae that didn't go dormant this winter. I stopped watering in November but the plant kept producing leaves and stayed completely green so I resumed watering in January, but it is dry for about a week between waterings.
    the problem is that it looks like the plant have finally realized that it is time to go dormant and the leaves are turning yellow. What do I do? Stop watering and then resume in late spring?
    Thank you!

    Stop watering until you see new growth.

    I have a beautiful tuber of Habenaria arenaria that's doing the opposite: It's January and it has already begun to sprout. ugh.... :(

    I agree with Marni. I have Thunia alba that can be a little stubborn. As soon as it gets a little cooler, I completely stop watering and it goes into dormancy in the following few weeks.

    My habenarias do what ever they want, whenever they want. Right now I have some just coming up, some just dying down, some in bud and some just finishing blooming. If I think of it next fall, I may try moving some into a cooler location to see if that will get them on a cycle closer to what I think they should be.

    Mine are usually well behaved to an extent (talking to you, mystery Habenaria "medusa"), but I guess they're deciding to change that delightful reliability up this year. Tried a new method of storing them (slight damp storage in plastic bags depending on the species), and I think the moisture may be causing some of them to wake up... I'm going to try the same as you next year. haha.

    Thank you everybody. I'll stop watering now then.
