Hi,
In between the "one that should be obeyed" and the fig-trees ... The first one wins ...
I would try to negotiate a second ( -temporary-? ) greenhouse ...
You're in Zone6 - so it is really too soon IMO to get fig-trees out of their greenhouse.
Here in Zone7, I already had two leaflets burnt and destroyed by frost - that was last week or the week before ... Those leaves were on in ground trees ( no pushing them to grow )... Imagine a potted full leafed tree ... It would have been toasted
.
Patience... Patience ... That is the key.
I had one young potted tree bugging me at home (sick looking ) and I put her in the garden ... Yesterday, she was really sad looking - all winter growth died back ... May be the full young tree is dead ... Time will tell .
