I’m a big fan of John Little’s work on creating wildlife habitat diversity using recycled building “waste”.
I have a possible garden project, where the builder has cleared some rooms to be replastered and refitted, and the leftover building material has been left outside.
Celtic Wild Flowers is a brilliant native plant nursery in Swansea, Wales. I found out today that Barry is a big proponent of using coal slag as a low fertility substrate. There is lots of it in South Wales!
I am really keen to know which plants will thrive in which substrate. Currently, I’ve only trialled growing Thymus serpyllum on crushed concrete, which does very well.
