does it spread?
No seed is
produced. Trad grows vegetatively - by cuttings. Any tiny fragment
of stalk or leaf can regrow into a whole spreading plant. As it
spreads it sends more roots into the ground, making it harder to
remove. In addition the stem easily breaks into pieces as you pull
or move it.
Pieces of stem
or leaf easily wash down waterways or are carried in mud on tyres.
many people dump their garden refuse in the bush, where it spreads
on the spot or is washed into the creeks. There it easily takes
up residence in the damp soils.
does it affect us?
Trad is a highly
invasive weed. It spreads rapidly over the ground in gullies and
temporary watercourses, forming a thick blanket of leaves. It smothers
low plants and seedlings and prevents light and warmth reaching
the soil. This prevents native plant germination and regeneration.
