Princess Flower Bush Out Of Control

Question

About 20 years ago, we planted a Tibouchina urvilleana (Princess Flower) bush in our seldom-used backyard. It eventually grew to about 15′ tall and branches about 10′ wide. With the current shelter-in-place, we started a good trim-back of the bush. We found that it has spread along the sides with many suckers, has pushed the back fence almost over, and is growing up now through the seams in the concrete patio. What can we do to eliminate or contain this plant at this point? Chemically or hiring someone to dig it out completely? We are in Northern California, Sunset Zone 14.

Answer 1

With such an invasive species, and not knowing how widespread the root system is- I would advise calling a professional. This will help to avoid doing more damage than good, since there can be unintended consequences for these situations.
