Hi! New here but need to kill stuff

aMrsin09

I know a lot of the questions I have you probably won't be able to help with because I live in a rain forest.  No, I'm not exaggerating, I live in Queensland Australia...but, a lot of the plants we do have are tropical house plants in the US, so....

Does any one know how to kill Heliconias?  Everything I find on-line tells me how to propagate them and well, these plants are the devil.  They are everywhere.  The patch I just dug up has roots as big around as my wrist. I'd like to kill the roots (the plant part is very dead at this point).

Right now the only solution I can come up with is to have my H "accidentally" spill some lawn mower gasoline in the area and for me to "accidentally toss a lit match into the same area.

Any information would be helpful.

All of the gasoline will not be consumed and you are essentially creating a hazardous waste site.  I'd contact Australian gardeners for helpful techniques. One that comes to mind is

good luck

Hey Jellisy

Have you tried brush killer, you should be able to find it at a garden center.  It's specifically formulated for more robust plants.

What herbicides have you tried so far that have not worked?

Please don't tell me gasoline was your FIRST idea.

Well, the gasoline part was tongue in cheek, but the fire part...

Not sure what herbicide H used to kill the plant but the roots are about 1.5 feet down.

I didn't even know they made bush killer, so that will be next.

Thanks.

Try glyphosate.

I use a mix of Vinager/Salt and a dash of dish soap and BAM Dead!

1gal of white vinager

1C salt

a pinch of dish soap

mix in a jug and pour over it. DEAD!

Yikes. I wouldn't want this in my soil. Glyphosate is much safer.
