Hello.
I have a citrus collection (lemons, oranges, mandarins, limes, citrons, calamondin etc.) and I think that it is time to move them because they overgrown my living space. For several years I tried to keep them in control by pruning them but now they got too large.
So I found a mansard room to rent. It is perfect for exotics. Lots of light and a good air circulation. Plus it is very well insulated.
The problem is that the owner doesn't have electricity there so I can't heat it. I am thinking to heat it in a different way (gas, wood) but it is kind of risky to let it unattended.

The temperature in the rooms were I keep my citrus varies from 62F(17C) to 75F(24C). But 90% of the time is 70F(20C).
The temperature in the room I want to move them varies from 40F(5C) to 60F(15C) or more. These days is around 50F 70% of the time.

The temperatures are going to rise from now on. In a couple of weeks we will have nicer weather, I hope, now that spring is here.

What will happen if I would move them there right now? They will loose their leaves or regress into dormancy?
In that room they are safe from winds and cold rain.

Now they are having a new flush of growth and some of them are flowering.

I don't have much experience with indoor container citrus--my key limes are mostly outside, only indoors when it is cold, but as long as they do not get freezing temps or sun exposure while cold, I do not see a problem.

I think is ok by moving them , they will adapt soon to their new enviroment
