THERE will be a blitz against the noxious weed boneseed in Mundaring and Kalamunda this month in a bid to stop further growth.
The fast-growing weed is a threat to native plants and degrades bushland.
Residents are asked to look out for the plant, which flowers this month, and report it to the Department of Agriculture and Food WA Pest Info line on 1800 084 881.
National Boneseed co-ordinator Hillary Cherry said the Perth Hills sported small, scattered infestations of the weed, which bore a bright yellow flower.
“In the Perth Hills, all plants found are immediately targeted for eradication. Plants have been found around Darlington, Mundaring, Kalamunda, Gooseberry Hill, Lesmurdie and Henley Brook,” Ms Cherry said.
“While many plants have been destroyed, there still may be some plants lurking in back yards or bushland.”
She said boneseed rapidly formed dense weed infestations, out-competing native plants.
“Boneseed is easy to kill, in most cases the plants can be pulled out of the ground by hand,” Ms Cherry said.
“For larger plants, the stem can be cut close to the ground and herbicide applied to the stem to kill the roots. But landowners must be careful not to spread any seed or leave pulled plant roots near the ground.”
