Sometimes its hard to know where to start?
How can this jungle of mine become a garden? What you need is a garden clean up. Clearing your garden back to the point where more productive work can be done. Once the initial clean up is taken care of you can get a better perspective on where to start making improvements or how to maintain it in the future. This is an ultimately satisfying process allowing you a fresh slate to work with, to have the garden you have always wanted.
