Before you start

Lay the hose and the edging in the sun for a few hours so they become more pliable and easier to manipulate.

Outlining the bed

  • 1.1Lay out the hose, trying several different shapes until you get result you like.
  • 1.2Squeeze powdered chalk along the outside edge of the hose, then remove the hose.

Digging the trench

  • 2.1With a spade, dig a trench along the chalk line, making sure the outside edge of the trench is vertical to support the edging properly.
  • 2.2 Strip off the sod inside the bed with a pick or a sod lifter.

Pro Tip

The trench you dig should be a uniform depth and deep enough that about ½ inch of edging sits above ground.

Place the edging

  • 3.1Place the edging in the trench, adding or removing soils as necessary to keep it level.
  • 3.2Prevent soil from failing back into the trench by working as much as possible along the outside edge of the garden bed.

Pro Tip

For the least noticeable joints, avoid joining edging at corners.

Cutting edging pieces to length

  • 4.1Mark the point where the ends of edging pieces overlap with masking tape.
  • 4.2Cut the edging with tin snips or pruning shears at the mark. A straight cut will make joint least noticeable.

Making a joint

  • 5.1Slide a coupler halfway into the channel at the end of one piece of edging.
  • 5.2Hold the end of the first piece of edging tightly to keep the coupler in place and slide the end of the second piece of edging onto the coupler.

Anchoring the edging

  • 6.1With a small sledgehammer, drive a stake into the ground along the outside of the edging every 3 to 4 feet.
  • 6.2Backfill the trench and pack down the soil.
