I have bunches of nettles in my yard. I would like to get rid of them without without regrowth. Any suggestions which do no require chemicals or tilling the soil ?
Where are the nettles growing? Is it a large patch, or are they scattered among plants you'd like to keep? If it is a large patch, you can smother them. The easiest way to do this would be to build a lasagna bed on top of them.
If they are scattered about with other plantings and assuming they're urticaria dioica, I'd grab some good leather gardening gloves, pull them and eat them. They're delicious and very healthy. I blanch them in boiling water to get rid of the sting, then add them to recipes just like you would spinach. I think the flavor is much better than spinach, though. Enjoy!
