Even though gardening is, for me, a solitary hobby, I do it for lots of reasons:
To bring people together
To make things beautiful
To be a good role model for my kids
To learn how to grow stuff
To have fun and feel happy
My hardscaping and garden spaces reflect my complete lack of interest in pulling weeds or doing any more maintenance that what is absolutely necessary. After all, I have a family and indoor chores that must be done. There's only so much daylight and everything costs money!
