We need more planting space so we are going to dig up some turf in the lawn for a new border. Being a beginner i'd like some of your advice please.
The border will be 25 ft long...but what width would you recommend? I was thinking 18 inches? Is that enough?
I shall loosen the existing soil and put a mix of compost, sand, grit and topsoil down a few inches deep. By the way soil is heavy clay. Is it worth installing a weed sheet? Was going to put wood bark down on the top of the soil to reduce weed growth. Is that enough? Or do I need the weed sheet too?
Thanks for any advice.
