- Species are native to North America and have been cultivated as ornamental plants in the UK since 1648.
- The species were first recorded in the wild in 1849 and 1916 and have the ability to spread very quickly, becoming widespread in England and Scotland by the 1930’s.
- Erect rhizomatous herbaceous perennial which can grow up to 2.5m in height.
- Stems are hairy, with alternate long narrow jagged leaves.
- Multiple flowing stems emerge at the top of the plant with clusters of small yellow flowers (less than 5mm) in late summer.
- The plant is spread by rhizome and by wind born seed.
- Can be confused with the native Goldenrod Solidago virgaurea.
- Cutting twice per year over several years (May and August) can reduce infestations in grasslands by preventing seed production and depleting the rhizome.
- Plants and rhizome can be excavated ensuring that lateral roots are removed, excavated material must be disposed of at licensed landfill.
- Herbicide application early in the growing season can effectively control infestations, the efficiency of herbicides decrease as the plant matures.
When treating large areas, a suitable grass and forb mix should be sown to prevent bare ground and colonisation of other unwanted species.
If you have concerns over Goldenrod on your land, if you are unsure of your legal responsibilities, or, if you would like a quotation for control, please contact one of our specialist surveyors. Treatment costs start at £380.00 + VAT.
