I operate a lawn and landscape maitenance operation. From time-to-time, I have clients ask me to do installs. I handle the simple jobs easily enough, and hire out larger jobs. I would like to get more involved with design and build. Problem is, I can't design. I do okay in my head or sketching a design, but I want to be able to make technical drawings. I have the tools, scale, templates, curves etc., I just don't know how to use them. I would prefer to learn this method before buying landscape design software. Can you folks recommend a book or something to get me started. I walk my local nurseries on rainy days to familiarize myself with plant material. Any help would be great. Thanks, Bill.
