Troubleshooting
Cat's Claw Vine problems — and how to fix them
Cat's Claw Vine (Macfadyena unguis-cati) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive spread
Declared a weed of national significance in Australia. Tuberous roots regenerate prolifically after cutting. Do not plant in frost-free climates near natural vegetation.
Wall and surface damage
The claw-like tendrils penetrate mortar, brickwork, and timber, causing significant structural damage. Use only on expendable or metal structures if grown at all.
Extremely difficult to eradicate
Established plants regrow from deep tuberous roots after cutting and most herbicides. Repeated physical removal plus systemic herbicide is required over several seasons.
Smothering of native plants
Grows over and kills shrubs and trees by shading them out. Creates dense monocultures in natural bushland.
Fence and trellis collapse
The weight of mature plants can collapse lightweight fencing. Ensure any support structure is extremely robust before allowing growth.
