Mike, I used to allow my plants to drop their leaves naturally, however, it left such a huge mess, so I started trimming the leaves before bringing them in. I have over 20 plants in pots of various sizes, that used to produce a lot of leaves to clean up.
I'm glad I got all of my plumeria and tender plants in, temps are in the low 30's this morning. Fall has arrived abruptly, with the 10 day forecast showing temps in the 50's to 60's in the daytime, and nighttime temps in the 30's to low 40's.
The outside time for all of my tender plants are done. I started rearranging the basement yesterday, to get the 2 pink and 1 white pudica plants closer to the window, along with my brugs. The pudicas don't drop their leaves during the winter, so they get watered sparingly, and have done fine overwintered like this for me in the past.
