I need to use strong weed killer on our out of control agapanthus, which is best?

[mssfsmith]

It was suggested that digging them out was best & I agree but painful arthritis is a problem for me & first I need to thin them out a bit so I can get in amongst them & try a bit of digging. A few weeks ago I dug out a couple of isolated plants, by the time I'd finished, I actually had 3 large things which looked a bit like onions on the tops with bits & pieces hanging off them. The plants sprouting from them (chopped off first) were definitely agapanthus & when I started digging, it looked like only 2 bulbous things but a 3rd one was just underneath - would they have been the rhizomes? I hope so! Can't supply photos yet, don't have computer abilities - sorry.

Hi @mssfsmith 

Sorry  about arthritis so  lets try killing  them  with poision and hopfully they just rot down so you can sweep them up more easialy,  Chipping them out  1 a day will get them and not over fill your green  bin and not hurt you too much i hope.

Spray the Agapanthus board leave should be there weak  spot here.

I dont know if they need super  weed  killer but here it is,

Do wear  water proof  gloves and mix outside in case of spills

Yates 250ml Tree And Blackberry Weed Killer Concentrate I/N: 3010221   $21^.30

Hi @mssfsmith,

The weed killer @Jewelleryrescue has linked to is about the strongest stuff we supply at Bunnings, so it should do the trick, but be cautious as it will kill pretty much any plant it touches.

You can use a paintbrush to ensure it is only applied to the plants you wish to remove.

Make sure you follow the manufacturer's instructions closely and wear gloves and long protective clothing when applying the weed killer.

Let me know if you have any further questions.

Thank you, Jacob. I haven't come across that brand but haven't looked very well yet!

I need really strong weed killer for tightly packed agapanthus & had a reply about one recommended by "jewellery rescue." Read it too fast & thought 'jewellery rescue' was a brand (dopey, I know) just thought it was a funny name for a weed killer.

Thanked Jacob & said I hadn't come across that brand but would look for it - well I suppose it'll give some of us a laugh - even me!

Hi @mssfsmith,

They were recommending Yates 250ml Tree And Blackberry Weed Killer Concentrate. 😁 I don't think @Jewelleryrescue has come out with their own line of garden herbicides as yet.

Hi @MitchellMc 

I saw a James bond movie where a beaker of his urine killed a man in a fight scene, I could try that on plants but maybe carcinogenic..  If it works, I will be standing next to a bottling machine all day hard way to make a dollar lol
