Lay Timber Edging
A simple solution to stop grass invading beds is to install edging.
It’s affordable and can be done in half a day, dramatically decreasing the time spent on garden maintenance.
On this coastal property, treated pine sleepers were used to define a border between the murraya hedge and buffalo grass.
A trench was dug and lengths of timber buried to half their height in the soil, with hardwood stakes positioned in the bed to support the edging.
A few runners may work their way under the edging but they are easy to pull out.
If after a few years the level of the edging drops too low it can be lifted out and a layer of sand added before replacing the timber.
For this project, choose H4 grade treated pine which is specifically for in-ground use outdoors.
It is treated to resist rot and insect attack. We used 3000 x 200 x 50mm sleepers buried to half their width underground.
This created a raised edge, making it easier to use a line trimmer to cut the grass.
If the sleepers are too long to transport in your vehicle you could ask the supplier to cut them down for you, but this will make it much harder to get a straight border and affect the overall look of the edging.
TIP: Drill clearance holes in the hardwood stakes and use galvanised screws to secure them if there’s a lot of movement in the ground.
