Repotting plants - Fall or Spring?

Q: I re-potted a mango tree into a five gallon pot, it looks great and is starting to bloom. Should I re-pot again while it is blooming or wait until spring? I will be moving the tree into the greenhouse when the temps drop.

A: You shouldn't re-pot any tropical plants in fall. Root system is small comparing to a new, larger pot. And it won't grow during fall-winter period. Therefore, you will have large volume of soil without any root in it, which may provoke rotting. Extra water will most likely cause over-watering of the plant. Wait till Spring to replant it.
