Where is it found?In and around old orchards and to a limited extent in shrub along roadsides and indigenous forests.
Why is it a problem?Very aggressive behaviour in indigenous forests of Norfolk Island and elsewhere in the Pacific. Could become a real problem in New Zealand.
How does it spread?Cultivation escape. Seed could be spread by larger birds such as kereru.
How do I get rid of it?
Cut down and treat stumps with herbicide. Hand pull seedlings.
Remove all seeds from trees and destroy. Felled trees should desiccate and decompose in situ. Seedlings should be snapped in half and hung nearby to desiccate.
Treat stumps with herbicide or scatter Tordon granules around stump.
Cut adult trees and treat as above. Hand pull seedlings.
More widespread than yellow guava, and can be difficult to see as it is not very distinctive.
