Wild Ginger is a real threat to our native species. It thrives in warm places that have rich and moist soils, learn how you can help to remove it.
Wild Ginger is usually either Kahili Ginger or Yellow Ginger (Zingiberaceae – Hedychium gardnerianum), its rhizomes form dense clumps which push out all other species, including within native bush and on road sides and riverbanks.
Wild Ginger is in our Dirty Dozen as due to it’s all smothering nature, it will eventually replace all other species.Wild Ginger is extremely shade tolerant, somewhat tolerant of frost and drought and can withstand immersion in sea water.
How you can help…
You can dig out the rhizomes of smaller clumps of ginger or apply herbicide to remove them. We find MetGel from Cut’n’Paste works a treat, for the best outcome you should cut just above its pink collar and quickly (within a few seconds) apply the gel. Try working in pairs, one cutting and the other pasting. Please always read the instructions on the label and wear protective clothing.
If you are in the Tutukaka area and need help or access to MetGel please contact us text 022 526 1972 or email firstname.lastname@example.org – our team of weed surveyors and slayers are only too happy to assist!
