Create a Flagstone Walkway

Even for a novice do-it-yourselfer, installing a mortarless flagstone path is a practically foolproof project. It’s not very technical and doesn’t require any power tools. It’s mostly labour, but there’s enough artistry involved to make the task satisfying.


 
 

1. Outline the edges of the path with flour. Measure the surface area of the path, then estimate the amount of gravel, compost, and flagstone you’ll need to buy.

2. Use a spade to excavate the soil between the lines to a depth of 12 to 15 cm; rake to smooth surface.

3. Spread a 5 cm of gravel over the area; firm down evenly with a hand tamper.

4. To ensure that the path follows your grade of the garden (essential for proper drainage), place stakes at each end, tie a string at paving-stone height between them, and attach a line level to the string.

5. Atop the gravel, place pairs of flagstone slabs to act as guide stones; lay the flat side of a timber batten on top of the slabs at the level of the string. Between these guide stones, arrange more flagstone pieces, using the batten to keep an even level. Use chisel to break pieces to desired shapes (wear safety goggles), but don’t make them too uniform - you want a rustic look. Allow a gap of 2 to 3 cm between pieces for planting seams.

6. Plant your chosen plant plugs from cell-packs; fill gaps with a mix of gravel and compost. Water thoroughly.

 
There’s just enough space between the stones for strips of groundcover to grow.
