I have a Ficus lyrata whose roots have grown out of the 25cm pot's drain hole. They form a dish shape within the pot's dish. Is it wise to cut these roots so that the pot can sit level again, or is it a sign that I need a larger pot?
I have a 10 ft tall Lyrata in a 30 cm pot. It has some roots out the bottom and a few over the top rim and down to the saucer. I don't trim the roots and I am not moving it to a bigger pot as this one is already a hassle to move out in the spring and back inside in the fall. So I think you can do what you want.
