This will be my 3rd year to try to save a Mandevilla from winter. My first attempt was just cut it back and keep at about 50F and lightly water. NOPE
Last year, I brought it in to work where there is a lot of flourescent light. NOPE. My problem here might have been that I had to uproot it to bring in.
This year, I left it in the same pot and moved from outside to the garage a couple days, now inside by a South window.
I tried rooting in water too. NOPE.
So I am debating whether to leave it at home or bring it into the office before the temp drops anymore. We should have a few more days at the end of
this week to mid next week still in the 70sF, but then I think it's going to drop big time.
