So - does anyone have a favourite garden design program?

Was it as long a go as that? Time fly's. I was also after some
software, back in the early days of computers, there were plenty, now
very few, and very complicated, I ended up with large jotter pad, and
made it up as I went along, refining, and changing.

Did a list of what I wanted, put it in order of importance and read
all the books I could get my hands on.
