Hi all, I’ve just been re-potting / pruning a couple of Bonsai Fig trees for some friends of mine & I'm a tad concerned that they may suffer from the cold temps of my garage. They have both been house in conservatories, which i assume are quite cold at night, so maybe my garage isn’t too bad. It say's in the reading i have studied that 15c or above is safest for them, any advice would be appreciated, but i will be trying to get them back to their owners ASAP as I don’t want them to suffer from the cold?
