Agapanthus – The spreading menace

Agapanthus a spreading menace. Kill it with MetGel

Agapanthus is a spreading menace with thick strong rhizomes in the ground. Planted as a pretty edging plant for borders, it quickly form dense clumps that take over and exclude other plants. Introduced from South Africa, it just loves NZ's warm wet climate and doesn't know how to stop. It has become a serious pest plant in areas of bush, spreading from people's gardens.

Go to this link to see and detailed description. It has thick strong rhizomes in the ground and is almost impossible to remove permanently by manual means.

Robust, clump-forming perennial. Rhizomes thick, long, white. Leaves 20-70 x 2-6 cm, leathery, arching, arising from base in clumps up to 20, sap watery. Flowers small, purplish-blue or white, in many-flowered umbrella-shaped clusters 7 x 5 cm, Dec-Feb. Seeds thin, papery, black.

See this link for advice of Agapanthus. They recommend our MetGel weed gel.

Simply cut down to the stumps and apply the gel to the freshly cut stumps. They may require follow up treatment in 6 months to a year.

Because it has thick strong rhizomes in the ground it is almost impossible to remove permanently by manual means.

Do not dispose of the remains over the fence as it will simple take off again. Hanging the plants up by the roots will often simply create an aerial ephiphyte.
