yes Lilith I agree with you about the cut logs - just perfect! Here we have used coconut trunks for the uprights (a friend was cutting down a 60 ft coconut palm that was leaning over his house) and waste coco logs for the edging of the beds. They work wonderfully and wildlife loves them as they are not treated. As well as about 10 different fungus, we have many ferns and small plants colonising them. OK they won't last as long as treated timber, but the benefits far outweigh the shorter lifespan and they blend in very well. I like a loose jungly effect rather than regimented plants.
