Tropicals & Tender Perennials: Overwintering Cassias advice please, 1 by ErickMN

Hello All.

Here is an evening picture of my lush and gorgeous Cassia alatas. I started them from seed last March. They've grown very quickly and have turned into real showpieces. I think (I hope) that I have tiny flower buds, so I am cautiously optimistic that I will see blooms before our first freeze in 6-8 weeks.

My question....What am I going to do with them over the winter? They will have to come indoors for 5-6 months. Should I keep them on my south-facing sun porch and keep watering them like a tropical? Let them dry out and barely water them? Cut them back and put them in the basement?

Any advice would be appreciated. I'd like to enjoy them in my gardens next year.

Thank you.
