Arum Lilies

Arum Lilies are beautiful and take over wet areas

Arum Lilies are so beautiful and yet they are very prolific and easily take over wet areas and gardens. Killing them has always been difficult until Cut'n'Paste MetGel. Our metsulfuron methyl based gel is very effective against Arums whatever the variety you may have.

Originates from South Africa. It was introduced to New Zealand as an ornamental garden plant and is thought to have been naturalised by 1870.

All parts of the plant are poisonous and one of the National Poison Centre’s top ten poisonous plants; being consistently involved in unintentional or childhood poisonings. Not something you really want to have in your garden.

There are many cultivars of this weed but normally the standard plant with white flowers is the one that has been the most weedy.

Auckland Council website has some good information on the plant.

Best treated by cutting down the to the stump and pasting with MetGel.

If the stump oozes a gel-like sap after cutting wipe this away before applying MetGel.

Important Notes:

⚠️ Safety Warning: MetGel and Picloram / Picloram Plus+ have significantly more residual soil activity than the glyphosate gels, and can move through ground moisture. MetGel has a soil half-life of roughly 30–90 days, and Picloram roughly 2–6 months, perhaps longer in clay soils. Do not use either near desirable non-target plants, within the root zone of prized trees, or around waterways and wetlands.
When using MetGel or Picloram, never apply it inside the drip line (canopy edge) of prized trees or broadleaf garden plants. On flat ground, keep a 3 to 5-metre safety buffer. On sloping ground where the weed is uphill from desirable species, extend that buffer to 5 to 10 metres.
Weeds often grow along streams and in gullies. If you’re working near waterways, use Bamboo Buster. Do not allow any weed gel to enter the water.
Only treat weeds / target plants / trees that are on your property, or that you have permission to treat. Be aware that some species might have protection status or have a notable status, or be a designated scheduled tree under the district plan – if in doubt, check with your local council.
Safety First: Wear gloves and protective clothing and observe all safety protocols, especially when using machinery, chainsaws and other tools.
When using any herbicide ensure you READ THE LABEL THOROUGHLY, and follow all instructions and directions for the purchase, use and storage of the product.
If in doubt, seek professional advice.
