When to bring the trees in?

[jadednightdragon]

I have a ficus and Fukien Tea and a Money tree. I was wondering when is a good time to bring them in. I live in Central Florida and a bonsai book says to bring them in when it drops below 60F. But I want to see if thats true or if they can go to a lower temp. I also have a seedling pine.

thanks in advance!

I leave my tropicals out until the lows start dipping into the 40s. The pine should always be outside preferably in the ground to thicken.
