Hate the look of plastic landscape edging? For a more informal, natural border around planted areas, try trench edging and mulch borders.
Dig a trench 4 to 6 in. deep and about 4 in. wide with a straight spade. Angle the sides outward at the top.
Fill the trench with wood chips or other organic mulch for a more finished look and to deter weeds.
Trench edging looks great in informal garden settings. Use trench edging as a border around spreading evergreens or groundcovers or in areas where vinyl or other permanent landscape edging material would look too formal and unnatural. You can easily shift it if plants outgrow the bed. An open trench (Photo 1) holds back the adjacent grass better than a trench filled with mulch. But if you prefer a more finished look, fill it with mulch (Photo 2). You'll have to redig the trench once in a while to keep it neat and to hold back the lawn, but it doesn't take long and you can add the trimmings to your compost pile.
