Hi I am new here. I am a total newbie to gardening as well : )

I have a small garden (approx 25ft by 20ft) some of which is decked.

At the bottom of the decking we have grass but after getting in a gardener and having it re-turfed and re-seeding it's not working so thinking of laying either gravel or slate but adding raised borders to brake it and keep it looking pretty.

Any tips? Would slate look odd as i prefer it to gravel?

Does anyone have any pictures of their gravel / slate gardens please
