Weed Control Forestry, Nottingham. PLANTFILES. During the summer, the hairy, black seed pods of Broom explode in the sun, producing an audible cracking sound and spreading their seeds. If only a single cutting can be made, the best time is when the plants begin to flower. Gorse control of Jughandle State Reserve: Resource restoration and development. Chemical control includes both broadcast and spot application. French broom: This is the most widespread and damaging of the weedy brooms, in some places forming dense, almost impenetrable thickets and invading native vegetation (McClintock 1985).
