I've got some large stones in my garden, some small ones too. I
arranged them into a small dry stone wall about 6 feet wide and 2 feet
high. I noticed that wood lice and slugs had made their home under the
stones and wonder if this is good for the garden, ie: slugs and tomato
plants don't mix. We have a wren in the garden and notice that they
like dry stone walls, so is it a choice between having a wren, wood
lice and slugs, or nothing. What's the best thing to do with garden
stones?
