Small acts of nature conservation.
A couple of these we already do but others would be new and different to work on this year, in the garden especially. Includes things like not raking up all the leaves in the Autumn. You can rake them off the grass and into the flower beds, good for the plants and the wildlife.
I've known about lawns being mowed in patterns for years, but didn't really think of it as a hobby, or an art form. It is though. So far I haven't found anything about it, other than how to guides. I would not be surprised if there is a group somewhere for lawn mowing art.
