Hi there, I have let our garden get a bit of a mess of late, so at the weekend, I popped to B&Q and got myself some weedkiller. I went out into the garden and filled an old watering can with a solution of this, and went a bit crazy. Unfortunately, before I gave it any thought, I had doused the weeds inside the little 'container' of earth at the end of our garden, in which I was considering planting some strawberries or such. Have I contaminated this earth and if so, how long will the earth be unusable? Thanks.
