Deadfast weedkiller??

Hi,

Ive been advised to use deadfast weedkiller on my recently dug-over garden to kill all the weeds below ground level (apparantly it kills the roots?).

I then want to lay my lawn in spring next year - is that ok to use?
Plus, i have pet rabbits but they wont be on the garden til end of december

 

Alot of the really strong weedkillers that kill the roots leave the ground in a state that you cannot plant in the soil for about six months - you'll need to check that. also check the labels for pet safety - it should be marked fairly clearly.

 

What is deadfast weedkiller? And who sells it?:D

 

Good question daitheplant.......I thought the OP was just talking about general weedkillers that act 'deadfast'.....as in quickly.....but a quick google and it is actually a product name. Given that this is the description that goes along with the product:

hmmm, it won't copy and paste.....and don't want to throw in a screen shot, but basically it's a sodium chlorate product that says it's intended use is for paved areas, driveways, patios, etc., places where you wouldn't be planting plants......

So no, don't think it is something that you should use where you want to plant grass......or where you want the bunny rabbit to play!

 

In that case... use a glyphosate based weedkiller (like 'Round-up')... now.. this should kill off any deep rooted perennial weeds.... that may not reappear before you lay the lawn in spring. and again before you start work in the spring, as some annual weeds will have appeared.

No... wait....I just re-read post 1.. you've taken off all the tops of the weeds already!

IF, the deep rooted weeds re-appear and are growing strongly, before it turns cold.... then as above... if they don't realy appear this year... leave it intil late Spring... and everything has re-appeared... then whack it with Round-up.

A weed killer will only work on healthy growing green bits... and then will be taken down though the plant into the roots

(Deadfast is a horrid, agressive name.. I wouldn't want it in my garden!)

right

 

Weedkillers containing sodium chlorate are banned from sale from 30 Sept - thank goodness

Any you have in stock may only be used until may 2010

 

i dont know about using sodium chlorate for killing off weeds.but when i worked in the chemical industry,before laying slabs and chips i used ,calcium chloride, CaCl2, flake and it was very fierce for killing weeds(and anything else in the vicinity!).the ground was barren after that. i would not reccomend using any thing like that. stick with a tried and tested and reccomended product.
all the best music.

 

"I then want to lay my lawn in spring next year"

Just in case if it's an option:

Weeds are starting to go dormant now.

Creating a lawn now, rather than in Spring, means that they have less weeds to contend with, and come the spring, when the weeds start in earnest, the lawn is more established - and will need less / no watering during the Summer too.

Weeds that do come up in the Spring get chopped by the mower - as the grass is well enough established by then to be mowed regularly.

Just a thought ...
