I recently rescued this beautiful calamondin tree from a friends garage. He had the tree in a 75 gallon smart pot in which he had plans to grow beans with the tree over the winter! I know, cringe.. He put the tree in a 5 gallon smart pot last spring, it grew well over the summer. Fall came, first frost in mid September, temperature gradually lowered into the low thirties every night.
My friend then put it in his heated garage claiming he was going to grow the tree for "profit" and had a 1000w grow light. He then decided that he couldn't' afford the electric bill (obviously), left the tree in freezing temperatures in the dark for a week.
I then rescued it, put it back in the smart pot since the roots filled the pot pretty well, took it home and gave it a good shower and much needed heat and 8hours of sunlight a day.
Fast forward 3 weeks; the tree lost only a few leaves (mainly to the cat) and now thinks its spring! Yay! I think we are going to get along well.
