About Cleavers

Cleavers is a highly invasive declared weed with potential to infest large areas of the southwest, causing environmental and economic damage. It is a robust annual sprawling herb with small sticky hooks along its stems, at the tip and along the edges of leaves and even on its fruit, which readily catch on animals, birds, clothing and machinery…..prompting common names such as velcro weed, sticky weed, bedstraw

 

Blackwood Biosecurity has kindly been funded by the State NRM Programme Community Actions Grants, in partnership with the Bridgetown-Greenbushes Shire to extensively map, monitor and control cleavers in the Bridgetown-Greenbushes Shire over the 2016/17 year.

Sticky, hooked cleavers seeds are dispersed by wind, water and by attaching themselves to people, machinery and animals (especially foxes, wild rabbits and feral pigs).  

 

Cleavers is regarded as a threat to agriculture and the natural environment and is highly competitive, smothering other vegetation.

Plants seed several times a year and survive for up to 3 years in the soil. Cleavers dies down over summer but re-emerges in Spring, quickly sending up stems which grow to around 2 metres.

Cleavers is very difficult to control with traditional methods, even when perfectly timed and diligently repeated, so Blackwood Biosecurity, with assistance from DAFWA, has commissioned Weed Scientist Jon Dodd to research a Cleavers Management Plan for our operational area.

 

CLEAVERS (Galium aperine)

Blackwood Biosecurity Inc. is concerned about increasing infestations of the invasive weed, Cleavers (Gallium aparine), in the Bridgetown-Greenbushes Shire and needs your help.
 
We are mapping Cleavers along roadsides and in reserves, but we can’t reach everywhere and ask that you look for it on your property and elsewhere and let us know where you see it.
 
Cleavers is an annual scrambling herb which dies down in summer and germinates again about now with winter rains. It is highly invasive, with potential to infest large areas of the southwest, causing environmental and economic damage. It has small sticky hooks along its stems, at the tip and along the edges of leaves and even on its fruit, which readily catch on animals, birds, clothing and machinery…..prompting common names such as velcrose weed, sticky weed and bedstraw. It often likes damp, partly shaded areas.
