Cape Ivy

Delairea odorata. Origin South Africa. Cape Ivy has the ability to smother native vegetation making it a very serious threat to many ecosystems. Locally is happy to infest roadsides, along rivers and creeks being very effective at competing for light due to their ability to cover the canopy of the plant they are growing over such as tree ferns either killing the plant or causing it to break and collapse. Did you know? • It is a vigorous climber which strangles or smothers indigenous vegetation and creates harbor for foxes and rabbits. . • Once established, the spread of Cape Ivy is usually vegetative and by seed. • Cape Ivy can root from any stem parts that touch the soil. • It especially likes moist areas. • Cape Ivy was introduced as a garden plant and may be available from commercial nurseries. • Likely to be toxic to both people and animals. Best methods for control Start with vines growing up trees to prevent flowering and further spread by seed. Cut climbing stems with secateurs and leave to die in shrubs or trees. Gently hand pull or dig up stem runners. Follow the long runners to their source, carefully removing these and forking out main roots. Large Established Plants. Treat as for small plants except carefully dig out roots or stems on the ground, or Immediately paint with a suitable herbicide any cut stump that is to be left in the soil. For large infestations spray foliage with herbicide, but avoid spraying any native vegetation that the plant is climbing vegetation that the plant is climbing through. If using herbicide, paint/spray when plant is actively growing.
