It's a process and every year you see an improvement over the previous one.
5 years ago I've had a meadow that was slowly overgrowing with trees and some old, mostly dead fruit trees that look like from a horror movie around the house.
With just me an my wife working on it we got to half an acre of a garden, a greenhouse, tiny vineyard (if you can call 20 plants that), 50-60 fruit trees and bushes. I intend to add beehives and a chicken coop before summer.
