We spotted a few wild orchids in the early days and simply let that patch of grass grow to become a 'mini-meadow' and I found it so much more interesting than a conventional lawn (and so much less work) that I extended the uncut areas. I strim them when they get too meassy, about the end of July, thoroughly raking off the cuttings, and thereafter cut them regularly with the mower set high.
It looks pretty awful for a bit after the first big cut, and it looks rough inthe winter but I like that it changes each year. This year there is a nass of bird's foot trefoil. Flocks of finches love when it all goes to seed.
I am calling the back garden 'rewilding' and feeling very on trrend!
NB If your soil is rich you may get many coarse grasses and docks and it might take few years of raking off all the cuttings so as to impoverish the soil before you get the wild flowers. You can grow wild flowers quite easily in plugs and pop them in to speed up the process.
Whereas a conventional lawn can look good all year round a meadow changes all the time and really only looks colourful for quite a short time, but for me the benefits outweigh the lack of tidiness and in the countryside that doesn't matter as much as it might in an urban environment.
