Weed Potential 
As a weed Montpellier Broom is highly invasive in regions with moderate rainfall invading habitats including grasslands, heathlands, woodland margins, disturbed soils and along water courses. Large stands can inhibiting the development of native tree or shrub seedlings and prevents ground flora from growing. 

The shrub grows in a variety of moderately fertile well drained soils and prefers an open to exposed sunny position. Seeds are produced within 2-years and the plant can live for up to 10-years producing masses of seeds that are expelled explosively from the parent for up to 3m (10ft). 

The very viable seeds can remain dormant in the soil for up to 10-years. Disturbance under plants stimulates seed germination and Broom can fix nitrogen in the soil adding fertility and encouraging seedling growth. The seeds 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 but a follow up spray will be required as it take many years to eradicate accumulated seeds in the soil.
