Best to wait until you have nights consistently in the 40's to be safe, unless you can easily move them back inside if necessary.

And I see Meyer Mike even suggesting temps above 55, since the roots are sort of exposed being in pots, versus citrus in the ground, which can withstand much lower temps. I personally would pull them out during the day if it's not too hard, as the sunshine and warm temps will do wonders for your citrus. But, that may just not be logistically possible if you have a lot of citrus, or they're in large pots :-)

Okay, thanks! That gives me something to go on. Maybe for now, I'll put them out when I see a few days coming up that will be good and bring them in if necessary. I just didn't want to be bringing them in and out and really freaking them out with the temp changes and such going back and forth.

You don't say what variety are your trees; but if any of them are Meyer lemon, the light is more important than the temperature. Meyers are a bit sensitive about light changes; and if you make a big change in light conditions, the tree will often respond by dropping many if not all of its leaves. Best plan when moving them outside is to move from inside to full shade, then in a couple of weeks to part shade, then later to full sun. Moving them indoors in the Fall should follow the reverse process.

Sorry yes, one is a Meyer Lemon and the other is a Key Lime. It should only be a week or two longer at the most but the lemon is getting funky looking leaves and I'd like to get them outside as soon as possible without causing more problems.

Everyone is on the same page here.

No one wants your trees to freeze, drop leaves, or die of rot.
I would personally wait until temps are average into the 50's for mine and introduce them to high natural light levels 'slowly' as John says.

Hello John and Patty!:-)))
