Our series of tips on “green” gardens continues  with three more recommendations from Carl Smith, PhD, a landscape architecture professor at the University of Arkansas School of Architecture and coauthor of the new book Residential Landscape Sustainability: A Checklist Tool.

Hail to the Heap

A garden compost heap made of veggie waste from the kitchen, as well as the leaves, cuttings and branches from yard work, can be rotted down over time to provide a ready resource of soil improver.

What’s more, as many as one in five truckloads of waste delivered to U.S. landfills could find a home on a compost heap instead.

Think in Layers

To attract the maximum biodiversity to your yard, you should use several layers of plants: ground covers, shrubs, larger shrubs and, of course, trees.

Hedge Your Bets

Housing, like all types of extended development areas, can divide areas of natural value like woodlands and grasslands.

Rather than build a fence, plant a hedge to help provide a “green corridor” for animals to move through your neighborhood and between fragmented green areas.

And if you don’t like your neighbors, you can always let your hedge grow tall!
