Hi cherryblossoms! That was one grand rainfall overnight huh? I was also surprised to see it at 2 am
Temps were not bad really it stayed at 61F, so all the plants can bear that rain and it really felt like warm rain. I see both our areas will just get spot showers the rest of the day, after that I see no rain again, just a chance on Sunday.
You can still bring them out today and all the way to next Thursday still. I would let those plants enjoy the brief touch of good humidity right now. Very seldom we reach this 93% humidity versus the usual 30% humidity and lower. And Plumies love high humidity. But keep your leafless Plumie in a protected area in case it still does rain.
Do not be alarmed if your Plumie leaves starts turning yellow later, that is just the plant showing it is starting to nap. That will make pulling them indoors easier, the plant is already showing you it is ready to go to sleep for the incoming cold season. Either you wait for them to do that or go ahead and cut the leaves. Either way the plants will sleep. Dry days are coming about again, so it will naturally dry the soil. The overnight temps though cool is still bearable, nothing showing below 55F there, so the cool temps will prompt the plant it is time to sleep. So expect those nice green leaves to drop soon. It will be just sticks afterwards, so either keep them in their dry soil or pull them from the soil and store in a warm area.
