posted 13 May 2013, 18:35 by Phelan Pirrie

MeACT sought feedback from members and supporters on the Auckland Council Draft weed management policy, and the comments and details from everyone was put into a submission we put in on behalf of the community (attached below).

When we have more information from Council about the final policy we will let everyone know of what the outcomes are and the implications for Muriwai.

November - Boneseed

posted 28 Oct 2012, 13:28 by Gerry Henley


Boneseed is a bright yellow, showy specimen from South Africa.  It has been showing its pretty yellow flowers for a few weeks now and will soon be setting seed. It can withstand coastal extremes and poor soil, so is right at home here in Muriwai. One plant can set up to 50,000 seeds a year.  If let go it will grow rapidly to form dense stands that shade out native plants.   Now is the time to nail it.

Recognize it: bright yellow flowers, bushy shrub can grow up to 2 – 3 metres.

Young stems are woolly but soon become smooth; leaves are smooth, leathery, oval to elliptical and irregularly toothed

Control it: Hand pull small plants.  Cut large plants at ground level and treat the stump immediately. If it doesn’t have seeds, leave on site to rot down or mulch. Plants with seeds must be buried deeply or disposed of at a refuse transfer station.  Replant cleared areas. Go to our website look under “Weedbusters Resources” for further information.

It great to see so many taking advantage of the weed bins at the Rangers Station.  Three bins were filled and trucked out. A great effort by all concerned. We are working on a plan to have a weed bin available year round.  We’ll keep you informed.

Call or email if you have any weed control questions, we can visit your site if you need assistance or advice.  Flax plants still available.

Weed of the Month - August

Velvet Groundsel.

 It must be spring; the daffodils are spreading a splash of yellow.   Further down the road however the other bright yellow flower is our weed of the month, Velvet Groundsel.  All the way from Mexico this is another one that has settled in well and doing it’s best to shade out and suppress native plant re-generation.  There are a few patches of it part way down Motutara where it has jumped the road and established on both sides.  It is also seen here and there around the village.

Pull up small plants now before seed sets.  Cut larger plants back to ground level and paint the stumps with Vigilant gel. Dispose of all plant material at a refuse transfer station. Use Vigilant in good weather as it needs about 4 hours to dry through, and apply with care, as it remains active in the soil. (Read the label and handle all herbicides with care). See further instructions on our web site.


We have been clearing Wattle and Elaeagnus along Oaia Road.  Wattle can be a good nurse plant but it can also take over large areas and does establish along the road corridors.  Do you want this Aussie taking over our streets, we don’t ? It is doing very well in many areas, much too well for our liking.  See our website for more information on controlling Wattle. If you would like to join our Weedbusting team send an email.  If you want to start a Weedbusting team in your street, we can help you get started. 

Flax plants still available, call 411 9951

July - Cape Ivy

posted 18 Oct 2012, 14:24 by Phelan Pirrie   [ updated 19 Oct 2012, 15:43 by Gerry Henley ]

Watch this weed:  July

CAPE IVY is flowering prolifically in Muriwai at the moment. It can be easily identified by dense clusters of bright yellow flowers as this plant scrambles over everything in your garden or along the road edge. This is the time to nail it as it is highly visible and seeds are not set yet.

Control: Hand pull small plants, or dig out roots (all year round). Dispose of at a refuse transfer station, burn, or bury deeply.  We are in process of establishing a weed disposal strategy for Muriwai.
