I took over a Field/garden used mainly to look after horses. I had to move a lot of earth to create different habitats in the garden including a large pond (my neighbour calls it a plake. Too big for a pond but too small to be called a lake) I do not have fish in it to encourage other wildlife . My great joy is watching the moorhens that appeared. I'm interested in wildflowers both English and Meditteranean and like to grow ones I consider beautiful and sometimes I'm puzzled why more people do not grow them. However I like a tidy garden so some formal but letting some go in a semi natural state. I'm still learning from my failures and willing to advise on my successes.(even though it may be just luck)
How the hell do I know. If I see something I like then I know.
