Lawn edging, most homeowners and gardeners will agree, is one of the necessary elements needed to keep your flower beds looking well-groomed and free of encroaching weeds and grass. What these same gardeners will probably not agree on, is the type of lawn edging you should use. Wood edging is one of the types of edging that is flexible enough to meet most of your edging needs.
Matching Your Flowerbed Edges
For flower beds with round edges, your choices of edging are virtually limited to edging materials you can make to conform to the rounded edges of your flower beds. Plastic will work, if it is flexible. You can bend it to match the curve of your flower bed. Bricks will work also and are small enough that you can arrange them in a curved line.
Wood edging, though, may be a better choice. Depending on the type of wood you use, it can be thin and flexible enough to bend. Then, you'll be able to follow your curved flower bed edge with it. The more inflexible wood edging can be used for square, rectangular, or angular beds without having to bend it.
Edging That Will Guard against Grass Intrusion
If your primary concern in using edging is to keep grass from growing into your flowerbeds, you should determine the type of grass you're wanting to keep out of your beds. For grass with shallow root systems, a narrow, 4-inch edging will probably work fine. But if you're working against Bermuda grass with its deep roots, you'll need something deeper. Bermuda grass spreads by sending shoots out from its roots. These roots are sometimes eight inches deep. For this, you'll need an edging that can be buried 10 or 12 inches into the soil.
Making Your Wooden Edging
Depending on the depth you want to plant your edging, you can use 1 inch lumber pieces, plywood, or even a wood veneer. If your flower bed edge is curved, use a tape measure that will bend and measure the perimeter of your flowerbed. Then, cut your wood edging to match these measurements. Be sure you treat any wood edging to resist moisture and insects. Otherwise, your edging will be rotted within two or three years.
Digging Your Edging Trench
Dig your edging trench at the edge of your flower bed. If you dig it further away from your flower bed and into a lawn or a grassy patch of soil, the grass will most likely grow into your bed. If grass outside your edging is Bermuda grass, be sure all the grass roots between your edging and the flower bed are dug up.
Planting Your Edging
Dig a trench where you plan to bury your wood edging. Make the trench deep enough so that when you plant your edging with the bottom of the edging resting on the bottom of the trench, you'll have about 2 inches of edging above the soil surface. Then, pack into the spaces on each side of your edging some of the soil you've removed from the trench.
