Most of my plumerias in the greenhouse are heading into dormancy, dropping their leaves. I have a Pink NOID that is not growing but not dropping any leaves at all. My Yellow/ Orange NOID continues to bloom and has about 5 more buds on it. The leaves are yellowing only slightly. In fact, I have only removed one leaf. Should I continue to water these plants until they shows signs of going dormant?

Yes, if they are not going dormant it is best to keep watering them. Just stop the watering when the plants drop their leaves. There is a great variance in the different cultivars and when they go dormant, I have found.

Thank you, Hetty! I sure am enjoying the fragrance from the flowers when I open that greenhouse!
I noted last year, the pink NOID kept 5-6 leaves on all winter. There is a good chance it might not lose a thing in the warmth of the GH.

My Celadine is still outdoors too, not going dormant yet and getting a lot of our rain.

'Riviera Rainbow' is still completely loaded with leaves and still has blooms too. It's the way some cultivars are.

Wish I have a GH. I have one with inflo, first time bloomer for me. If we get a warm winter it might bloom for me, if not , I will miss the bloom and will get new branches instead.
