I'd set aside a small area in the garden for winter vegies, but discovered yesterday that my partner has sprayed weed killer there. Is it now contaiminated for a long time? Is there anything I can do with it?
I have seen @CathM post on this topic. She advised that your garden is not contaminated but you can use mulch to help build up the garden and remove any chemical residue. Once you build up the soil level any chemical residue will be lower than most vegetable roots reach. But you would need to wait a few weeks anyway as if you are putting compost down it will be too hot. Hope that helps.
In addition to composting, a liquid fertiser like Seasol will help improve the soil and break down any chemical residue that might be left behind.
It depends on the type of weedkiller that your partner has used...if it is Roundup or weedkiller containing Glyphosate - these will disappear quite quickly - usually within 2 weeks.
Do you know what weedkiller was used?
It was Round Up @Branchy249. That is reassuring that it won't hang around for long. Thanks for everyone's help.
