How are thistle seeds dispersed?

Seeds are facilitated in wind dispersal by loosely attached, featherlike tufts called pappi. Canada thistle seeds separate easily from pappi, so they may not travel as far as generally thought.

How do thistles propagate?

They grow only from seed; plants do not spread from the roots. To kill nodding thistles, cut the stem below the flower head. If another flower head forms, cut again. No digging is required.

Will thistles spread?

Perennial sow-thistle spreads by underground roots but, in contrast to creeping thistle, these are largely confined to the surface 15 cm. Spread by seed is also important and these are dispersed by wind. Seeds may survive up to 5 years in soil and seedling emergence is largely confined to the spring.

How do you stop thistles from spreading?

Spray one to two sprays of vinegar directly on the cut of each thistle plant. The cut allows the vinegar to spread to the roots more quickly, which in turn kills the plant more quickly. Saturating the unwanted plants once a week with this mixture helps control the problem.
