What wonderful spaces you have all created. I have a small area behind my home that is land owned by the motorway behind us and they let me potter around there as long as its tidy. Its great because I never see another soul out there on weekends and only very occasionally during the week when they send maintenance crews to clean the storm water drains and clear paths.
Its a long narrow strip of land and directly behind my fence I've planted native flowering trees and shrubs to encourage native birds and animals to visit.
Behind my neighbours home I have planted a mix of native and non native plants around 2 frog ponds and created a small clearing big enough for one where I do rituals/meditations and just sit out there to read and relax when its not cold wet and wintery
