Transplantation of indoor lemon tree

Question

How do I know when I need to transplant my lemon tree in a larger container?

Answer 1

If you are seeing roots coming out of the current container, this is a sign to repot.
Select a pot that is big enough for the roots and a bit more room.
Make sure it has good drainage holes.
