I hate them, they are taking over ! how oh how can I deal with them ? they are tangled up with all sorts of other plants, I would like to poison them but think I would be killing half my garden. Oh how I hate them. Help !

pull them out ,as I did, one by one.
Thankfully I realized their behavior in time.

Pretty flowers though.

Yep. I had them at one house, dug down and the matted roots went for miles, never could get rid of them all.

Persistence. It isn't their fault, they are just doing what they do, breeding.

Just curse the one who planted them!

Is there a poison I could paint on their leaves ? I can't spay them, as in middle of more desirable plants. I would happily spend hours carefully painting the leaves if I could get rid of them.

You can give them a headache by CUTTING them back. I once read that the flowers should never be cut to pick them as it reduces blooms and I thought "that's a blardy good idea!'.

Try cutting them one at a time at ground level then immediately dabbing each cut surface with neat glyphosate (roundup)

The very best way is digging those horrible ugly grub-like tubers out. you'll have buckets full of them!

I pull them out as I see them, tubers and tops, into a plastic bag, and into the household rubbish. Most of the plants in my tiny patch are from windblown seed so picking the flowers is a good way to cut that seed dispersal down.

Cut the tops off a few and immerse them in 25% Banvine. They'll soak it back to the root base and that's it.

Woody weed killer painted on the leaves.

It travels to every part of the plant and kills it.
