What does it look like?
Bamboo is the common name of various species of tubular grass introduced to New Zealand from East Asia. They are tall and erect with smooth stems. Leaf-blades are lanceolate shaped (narrow oval, evenly tapering to a point at each end). They are also, alternating and have numerous ribs.
Why is it a problem?
Rapidly out-competes out other plants including native trees, forming dense stands or a mono-culture of bamboo and nothing else. Also an issue in gardens as it spreads quickly.
- Cut back regularly to help stop the clumps from spreading.
- Dig out runners and cut out regrowth.
- Cut off two stems per square metre below a node and fill tube with undiluted glyphosate.
- Cut off all stems and spray stumps with (1:3) i.e. 300mL glyphosate / 900mL water.
- Cut off and spray regrowth with Gallant 150mL / 10L water + penetrant
OR 300mL Amitrole / 10L water.
