|Tuesday Tools & Products: Sundials|
|Written by Heleigh Bostwick Tuesday, 09 October 2012|
Sundials measure time according to the position of the sun and are often used in modern day gardens to provide a focal point, especially in an herb or perennial border. Most sundials either lay flat on the ground such as this brass sundial or on top of a raised pedestal, and some sundials are more three dimensional in nature like this small cast iron sundial.
If you're only interested in using a sundial as a focal point, then it doesn't matter too much where you place it. If you want to use it to tell time, then there are a few things to consider regarding placement. The area should be flat, level, and in full sun. At 12-noon on a sunny day, position the sundial so that the gnomon or shadow arm is lined up with the noon mark on the sundial. The sundial must be re-positioned four times a year on April 15, June 15, September 1, and December 24 to ensure accuracy.
When it comes to sundials, there are a couple of options. You can buy one from a garden center, you can have one custom made, which takes into account your particular latitude and longitude, or you can learn how to make your own sundials.
