Spraying Weeds Near A Vegetable Patch.

Applying weedkillers near your lettuce patch it depends what sort of weeds they are.If they are annuals,I would just hoe or hand weed.If, however, they are perennial weeds I would spot weedkill by painting them with a translocated weedkiller like Roundup if the lettuce are already growing so that there is no risk of spray drift.If this patch of ground is as yet unplanted then I would spray with Round Up.RoundUp is inactivated in contact with the soil,so does not harm subsequent crops.
