Weed Potential 
As a weed Tutsan is invasive in cooler regions with moderate rainfall invading habitats including moist woodland and along water courses. Infestation form dense closed stands inhibiting the development of native tree or shrub seedlings and prevents ground flora from growing. 

The shrub grows in moist fertile well drained soils and tolerates a shaded to open sunny position. Seeds are produced within 2-years and are dispersed by birds, animals, machinery or water and in garden waste or in soil.

Control methods include physically digging out seedlings checking that all the roots are removed. Shrubs with fruiting branches should be bagged and removed off site. They may also have the trunk scraped or drilled, then paint with a non-selective herbicide.

 Small plant or seedlings may also be sprayed with a non-selective herbicide during early summer while the plant is active. Follow up spray will be required to eradicate accumulated seeds in the soil.
