Help me wage war on my Cordyline!

[FanjoForTheMusic]

Even though the stump has been ground to smithereens the leaves have resprouted. What can I do to get rid once and for all?

I suspect you'll need to dig a trench aroung the roots and attack it with an axe or similar and thenlever it out when the rots are severed! The roots are pretty soft so shouldn't put up too much of a fight!

Oh dear. There are other plants around it, so that sounds a bit nightmarish. Would any roots remaining in the soil sprout leaves? There are lots of fibres still in the soil from the stump. The two clumps of leaves that are growing now have a gap between them where the stump was IYSWIM.

My neighbour has suggested exposing what may remain below the soil, drill holes and pour in petrol or diesel. Surely this would poison the soil?

why do you want to kill it? They are lovely imo.
Ive unintentionally killed 3 in two years, so not hard to do!

I really like them when they're a tree with a trunk, but the previous owner of our house cut the tree down but left the stump, which then sprouted into a 7 foot tall bush of cordyline leaves! In front of a window.

How did you unintentionally kill them?

i forgot to cover them up in fleece when it snowed, so they went rotten

Something I've never tried but folklore suggests works... is to bang a few copper nails in any tree/shrub you want to die... Usually discussed in connecton with a neighbours leylandii! !!!

Alternatively try repeated treatment with glyphosate gel on any leaves that have the temerity to sprout!

Ooh, keynesian, I like the idea of that cunning subterfuge. Not sure where I'd hammer them in though, as I just have very large sprouts of leaves firing out of the ground!
