Hi, all :)

Up on the attic, I have a few lemon and orange trees that are stored for overwintering.

Average temperatures that we are going to have in this period is going to be 55-60F (or 10-18C) during the day, but the morning temperatures are going to be 35-45F (2-7C). I looked up the prognosis, and it says that the temperatures during the day in 2 weeks will be around 45F (7C).

I would like to put my lemon trees outside on the sun (they get light in the attic, but not much sunlight and warmth), inside a plastic greenhouse + they would have warming cloth on them during the night for extra protection). Because of those temperatures in 2 weeks (which are low), do you think that I should put my lemon tree outside or wait the beginning of March when the temperatures are going to be high as now (55-60F)? Those trees that I have can go up to -6C, but I have a big fear that the trees will freeze or be damaged by the cold.

The temperatures on the attic are pretty much the same as outside (give or take few Celsius), but I have trouble giving the the right degree of humidity and light + there is a big chance for me to overwater it because there is no warmth/sun to dry the soil.
