Trick Sneaky Grass

Q: What do you suggest for edging?

A: Grass is so sneaky. It can get over or under any barrier. But it can't grow in air. So edge perennial beds the British way, with an 8-inch-deep trench. Every year, set up a string line on stakes along each bed. On the lawn side of the string, chop straight down with a sharp spade and make a little cliff, then slope the soil gradually back up toward the perennial bed. If grass grows over the cliff, you can spot it immediately and deal with it.

Shown: Containers lush with purple petunias, pink geraniums, and large-leaved cannas create a low wall around Proctor's dining patio, giving the 15-foot-square space a sense of enclosure while allowing views into the garden beyond.
