Sketchup

Hello All,

I've just bravely downloaded Sketchup to see what it's like for garden design.  I've got a lot of learning to do as it looks really complicated (I'm not technical), but does anyone know which template is the best one for garden design?  It's the first question it asked and I don't even know that! They all mention Urban Planning or Home Improvement or Landscape Architecture (no Garden Design) but I'm looking for something with fences, walls, trees and plants.  Any Sketchup experts out there?

Thanks everyone
