Well here's my little contribution to the thread.
We purchased a house a couple of years ago, and sadly the previous owners (although fit and well, in their 40's) hadn't done anything more than cut their grass over the 10 years of more they lived there.
When we arrived we where faced with massively overgrown conifer hedges, and very anti social conifer trees that we removed all together. There was an area of land that had been totally left wild over the years, which we had to remove, leaving really bad soil.
The grass has so much moss it was unbelievable, the lawn was also in terrible condition from the clay soil, the unevenness and lack of any care over the years.
The plan was to remove all traces of all conifers, and then plant a fully native hedge. We'd loose a lot of privacy for the next 5-10 years, but out neighbours are great and it's just one of those things you have to do.
The lawn was in such a state, I decided to kill it all, get some soil and compost in and start afresh.
600 native hedge plants, 40 tonnes of soil and20 tonnes of compost later, (and more DOMS that you can imagine) we are now looking like this:
We now have 15 fruit trees, 8 in the nearest part of the photo and 7 new ones at the far end of the garden.
The nearest part is a couple weeks old wildflower meadow, so only grass growing thus far, but a few weeks or months there should be a lot more colour, I've also made a couple of strips of wildflowers road side where there was only bad grass last year.
Where we levelled the garden with compost the grass is a million times better than the old soil.
20 chickens are now doing their best to compost the whole garden, and as a 5-10 year project it should come along nicely.
I'll post some of the little garden and a new rear hedge once I get a minute.
