Hi there, I am new to this site and fairly new to gardening!
Are there any good sites whereby I can upload photos of my garden and design it further?
I used the low tech method of taking photos, putting it in a plastic sleeve, and drawing on it with wipeable felt tip pens.
Having done techie drawing etc, I'd measure out the plot and draw it. Include the locations of the things you have that you are keeping. Trace the drawings and print out copies that you can then doodle on to decide what and where you want stuff. If you haven't done drawing of that kind then measure up as best you can to get the boundaries at least, and take pix as fidget says. Don't forget some pix of walls, fences and anything which overlooks your plot that may impact on your design. Look at magazine and books for pictures of gardens so that you can decide on the look you like best and list any little features you'd like to incorporate. Just make sure that when you doodle - it's to the right scale for the plan. Many people have thought 'I could put a big table and 6 chairs in that nice little spot' - only to realise the nice little spot is really about 3 feet square!
Then remortgage your house so that you can build it all!....
