Small Ficus standard root issues?

Question

I have 2 small ficus standards about 3 feet height. The leaves are shaped into balls. If I continue to keep the ball of leaves small (about 1.5 to 2 feet diameter) by regular pruning will this control the growth of invasive roots from spreading?

Answer 1

I don't think so. I think you need to cut the roots every year. We used to control our clumping bamboo this way by chopping off the runners (that were getting away) in the ground. This is supported by this article.

Ultimately, my suggestion is to put it in a pot and bury most of the pot.
