With this nifty app you can find the path of the sun across your own garden for any day of the year. Just plug in your address in the search bar.
According to the description on the site:
SunCalc is an app that shows sun movement and sunlight phases during any given day at the given location.
You can see sun positions at sunrise (yellow), specified time (orange) and sunset (red). The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider show sunlight coverage during the day.
