This noxious weed also spreads into bushland from dumping or by
invasion from adjoining gardens. If left the plant eventually forms
a dense mat of tuberous roots which suppress the growth of indigenous
plants. It has long, prickly, arching stems which can grow up to
2 m long. The red berries drop off the long stems and ensure the
plant’s constant survival and spread.
Asparagus Fern is a South African plant, and not a fern at all but
in the Lily family. It is a dense scrambler with small pink flowers
in late summer, followed by red berries in winter/early spring.
These berries are very attractive to birds, particularly Currawongs,
who help spread it far and wide.

Control & Removal Methods
The whole plant can be dug out with a mattock, or with a knife if
it is a small plant. But probably the easiest method is to cut off
the long stems (remember the plant is prickly so wear thick gardening
gloves) and place them in a bin or bag for the green waste collection,
particularly if there is any fruit on them, whether green or red.
Then, with a sharp knife, “crown it”, that is, cut around
the root base removing the centre of the plant. The rhizomes and
“bubbles” (water tubers) can be left in the ground where
they will eventually die.
The best time to remove the plant is at flowering time or before
any fruit forms, then the long stems can be left to dry and later
used as mulch. The “crown” must be disposed of in the
green waste collection along with any seedlings that can be removed
whole. Remember to check the area every so often for any seedlings
that have grown from dropped berries.
