Basically there is a large patch right in the middle of the garden (surrounded by 3 beds and a path) which was at one point the lawn. However for various reasons it deteriorated over the years, and ‘dig it up and re-sow the lawn’ was added on to the list of things ‘to do at some point’ which of course never actually happened.
In the meantime a lot of it has died off, partly due to neglect, partly due to Bindweed, partly due to past efforts at removing Bindweed. As it currently stands it is a predominantly bare patch of ground with a handful of shoots of grass and bindweed scattered across it, with one end much more grassy, but also choking with the bulk of the bindweed.
Personally I’d like to at the very least, reduce the size of any hypothetical future lawn anyway to make more room for flowering/leafy plants but that’s another debate entirely.
