Climbing asparagus is a serious pest plant!
It climbs through, up, and over native plants, slowly smothering them.
It forms dense mats covering the ground, stopping new native plants from establishing.
Growing quickly, it can rapidly take over an area.
This perfect trio of features makes climbing asparagus (Asparagus scandens) a weed to take notice of. Originally from South America, this plant really shouldn't be here and is often spread by root material being dumped - so please report any garden waste dumping!
Pulling plants up when they are small can be a good method of control, but the tiny nodules in the roots often break off and stay in the ground, where they grow into a new plant.
Get in touch if you see it!

What can I plant instead?
What can I do to get rid of it?
Important: disposal of the roots and rhizomes is most important. The stems and foliage can be left to rot down. Berries should also be collected and disposed of if present
Dig up roots and rhizomes
Dispose of roots/rhizomes in a container of water with a lid or in a heavy duty weed bag to rot down over a number of months. Alternatively, dry them out, or burn them
Cut down stems and foliage and leave on site to mulch down.
Careful spot spraying can be used to treat seedlings and regrowth - talk to us about borrowing spray equipment.*
For larger infestations:
Cut away all stems and foliage in one go close to the ground, then return and treat any regrowth after a few weeks, or dig up all remaining clusters as they appear.
Talk to your friends, family and neighbours about how bad climbing asparagus is and encourage them to take action too!
See more pest plant information on our website.
*always read the label before using any herbicides. Other herbicide treatments are possible.
