I don't know about you, but we have a few tropical (read: indoor) plants that we put outdoors for the summer. They love the bright light, and the warm days and nights. This is my Night blooming Cereus. She has doubled in size this summer, being outside.
BUT...I just saw that the temperature is going to drop this Saturday. When the night temps drop below 50°, we bring everybody into the basement. My weather source shows 50° on Friday night, and 46° on Saturday night. That's fabulous for us, but some plants can't take it.
We don't haul in the mums, or other hardy stuff, but it's a good idea to either bring in or protect your tender indoor plants. It's a big job, but we will bring in the Benjamin fig, cereus, and a few others. The small ones may go back out during the day, but the big ones only get moved once!
Before bringing them back inside, like today, I will hose down the leaves, and deep water the pot to get rid of any creatures who may have moved in over the summer. Mostly, I'm looking for ants. I don't want them inside!!! This will give enough time for them to relocate, and the plant to dry enough to move it.
If you have put out your philodendrons and pathos, sansevierias, or Norfolk Island Pine, you might consider shifting them to their winter positions. They will love you for it.
HAPPY GARDENING!!
