They like to be kept quite dry with only occasional watering. They enjoy our sandy, well drained soils. They love our sun, heat and are very drought tolerate and endure our cold winters. or Century Plants are native to the southwestern states and New Mexico. Maintain pest and livestock control, as broom is not browsed as readily as native species and recovers more quickly from browsing.Agave spp. These sites can be left, regeneration can be speeded by slashing, selective spraying or replanting of shade-creating species. Light lover, so is succeeded in tall canopy habitats by taller native species where their seedlings exist (not in kauri or tanekaha forest). Not long-lived, relying on seedling replacement. Colonises bare areas, reinvades after non-selective spraying, fire or soil disturbance. Spray (spring-summer): metsulfuron-methyl 600g/kg (7.5g/15L + penetrant (knapsack) or 35g/100L + penetrant (spraygun)) or a product containing 100g picloram+300g triclopyr/L (90ml/15L (knapsack) or 200-300ml/100L + penetrant (spraygun)). Stump swab (all year round): triclopyr 600 EC (50ml/L) or triclopyr 120g/L (250ml/L) or metsulfuron-methyl 600g/kg (5g/L).Ĥ. Pull or dig small plants (all year round). Introduce biocontrol agents where possible - contact your regional council for more information.Ģ. Control only where broom is a recent threat, of low incidence or poses a high ecological threat.ġ. What can I do to get rid of it?įirstly establish plant is not native broom. River systems, shrublands, forest margins, low canopy habitats, coastline, tussockland, fernland, wetland, consolidated sand dunes, gumlands, regenerating and disturbed forest, and bare land. Increased nitrogen in gumlands and other impoverished soil types may result in changing habitats and plant species being present to the detriment of specialised plants eg orchids, ferns, herbs, kauri, or can lead to further weed invasion. Dominates low canopy habitats, preventing the seedlings of native species from establishing. What damage does it do?įorms pure stands in many habitat types. Common seed sources include quarries, roadsides, forest tracks, metal dumps, fire breaks, exotic forests, skid sites, riverbeds, domestic gardens, and disturbed land. How does it spread?Įxplosive seed mechanism spreads seed 1-5 m from the parent plant, and they are also spread by machinery, soil and water movement, and possibly birds and feral pigs. Tolerates warm to very cold temperatures, most well drained soil types, grazing, fire, and high to low rainfall. Particular problem on riverbanks and lakesides, roadsides, forest tracks and firebreak areas. As it is a legume and can fix nitrogen in the soil, it can change the types of plants which can survive where it has been growing, disturbing the ecology of an area. Prolific seeder that spreads rapidly, matures quickly, and colonises large areas, forming pure stands that dominate habitats. Tree lucerne, Teline stenopetala, and native Carmichaelia species are all similar. Single or paired, golden-yellow (occasionally reddish), pea-like flowers (15-25mm, Sep-Apr) are followed by oblong green pods (30-60 mm) that turn black as they mature and eventually disperse seeds explosively, leaving empty coils hanging from the plant. Leaves are divided into three sections (each 5-20 mm) that readily fall off the stems. Silky-hairy young twigs mature into woody, flexible green stems that are 5-ribbed and hairless. English or Scotch broom, Sarothamnus scoparius Where is it originally from?Įurope, Asia Minor, Russia What does it look like?Įrect, much branched, almost leafless, deciduous shrub (<2.5 m) with a woody rootstock.
