We have a ficus varigated variety, it is now getting huge. It is 10 years old. It is beautiful but is it going to be invasive?

No not invasive; I don't know what you mean by huge.

Thank you Tickle. By huge I mean about 2 metres higher than my single story house roof. The drip line is about 4 metres in diam.

Invasive typically means spreading roots everywhere and plants coming up all over the place. You have a big Ficus. Judiciously prune back to the size you want.

Thank you ma0641. Will the roots then be restricted to the drip line or do they just run riot?

Hard to say but drip line is normal.

The roots go every where but there are controlable with pruning as to size bejimina ficuses get about 90ft tall and 300 ft wide
