Q.Wilted Schefflera
I have a 28-year-old schefflera. My husband and I recently took a 6-week trip and when we returned, the plant was very wilted and looked like a closed up umbrella. We live in northern Michigan and had turned the heat down to 50 degrees and watered the plant well before we left. I’ve watered it twice sparingly since we’ve been home, not sure if it needs water or was over-watered before we left. It’s always been very healthy until now. Could it possibly be shock due to the lower temp for so long? I really hate to lose this plant since I’ve had it for so long.

It could have been the lower temps and it could have been that the deep watering it got before you left caused root rot to set in. I would check for root rot (https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm) Regardless, it should recover if the stems are still alive. It may lose some (even all) its leaves, but will regrow from the stem.
