Trench Edging

Tools

• The look of trench edging is determined by how straight and clean the trench is cut. A spade with a flat blade and straight edge is the best tool for neat trench edging. Use one with a long handle to avoid bending over and hurting your back. It's advantageous to sharpen the edges of the spade with a file to make accurate cuts that slice easily through dirt and grass roots.

Preparation

• Preparing a garden for trench edging is simple. Trenches are typically 3- to 4 inches deep, or enough to remove grass and root systems, and about 6 inches wide. The best way to ensure your cut lines will be straight is to insert wooden stakes 6 inches away from the perimeter of the garden and stretch string around the stakes. If the garden edges are curved, use a rope to create an outline for the edging.

Installation

• Creating trench edging is a straightforward process, but it requires care. Take the time to ensure the spade is positioned in line with the previous cut to ensure smooth lines. Throw removed grass and weeds in a compost pile, and add removed soil to your garden bed. Once the entire trench is cut, slope the interior side towards the garden with a rake.

Maintenance

• Trench edging calls for light but regular maintenance. Plan to pull wayward grass and weeds from the walls of the trench every other week. Re-cutting the outer edge at the beginning of spring and fall will keep the lines crisp.
