Twenty-five years ago when my wife Kathy and I started searching for a new home for our growing family, she focused on all the qualities one looks for in a new house. I, of course, looked at what every gardener considers imperative—the lot. Thanks to Kathy, we ended up with a wonderful new place. And much to my delight, the property had one particularly important feature—good soil. The other nice bonus was that the backyard bordered a small city park, with lots of open space for the kids to play, so my garden design did not have to include an area for kicking a soccer ball. Plant-wise, however, there wasn’t much other than invasive shrubs and trees. So after removing all the nasty invasives, I had a clean slate to work with.
