Week 2 – Blue Periwinkle
Monday, April 20 – Sunday, April 26
Periwinkle is a lot less physically challenging than last week’s Blackberry assault. But it’s still very difficult to eradicate.
We recommend poison (Metsulfuron-methyl) but only after you have whipper-snipped as much as you can and actually removed and binned/disposed of all your cuttings.
Periwinkle will just keep growing if you leave your cuttings on the ground.
If you are uncomfortable with chemicals, just let us know on the Facebook page – https://www.facebook.com/BlackwoodLandcare/ – and we’ll come around and do it for you.

There are three maps (from 2013) showing Blackwood and Barry’s Reef infestations:
