Onehunga Weed

Onehunga Weed

This summers prickles, onehunga weed, is in its growth season right now !

The Piha Domain has more and more of this weed  each year.  I don’t spray a lot but each spring I do spray our properties for this ghastly thing as in a couple of months it’ll be prickles. I like to be able to cruise around in bare-feet in summer – always have.

We don’t’ have a lot on our property – just where people walk as that is how it is spread.   Maybe Council could look at dealing with the plethora of weeds taking over Piha or at least the Domain?

Onehunga Weed – Yates

Onehunga weed is an annual weed which looks like a small ferny rosette about 20cm in diameter. Flowers are a tiny greenish-yellow. Seeds germinate in autumn but the Onehunga weed doesn’t put on much growth until spring. By the middle of spring each rosette of leaves contains a flowerhead with many spines. Seeds mature and drop from the plant by about the middle of summer. Onehunga seed is spread by foot traffic or on the fur of animals. The best time for control is when the plants are putting on their flush of growth during spring. When the seed heads have formed, uptake of herbicide is limited and control is usually not very successful.
