Weedkiller - how long till soil can be used

[StopnSmile 10]

Hello all

 

I was jsut after a little advice really, does anyone know how long after putting weed killer down I can plant in the soil?

I have a patch that I wish to use for fruit and or veg but not so long back I covered it in weed killer (not the brightest idea I know but I did it all the same) to save weeding it - what should I do now, if I mix in more soil and leave it till the new year will it be ok to grow in?

Thanks

It depends on the weedkiller, systemic sprays become inert upon contact with soil so you can plant right away. If it's a pre-emergent then that can stay in the soil for years.

Usually takes about 4-5 weeks to ensure the grass isn't affected
