How to use treated pine for garden edging

Using treated pine for garden edging can be a great choice as it is durable, cost-effective, and resistant to decay.

Treated pine is less expensive than hardwood and can be easily cut into boards and planks of various shapes and sizes. The difference in cost means that treated pine is more affordable for DIY projects.

Here’s our step-by-step guide on how to use treated pine for garden edging.

Measure and plan

Start by measuring the area where you want to install the garden edging. Determine the length and height of the edging boards you’ll need. Consider whether you want a straight or curved design.

Choose the right treated pine

Look for boards that are specifically treated for ground contact or garden use. It’s important to use treated pine that is safe for plants and the environment.

Prepare the area

Clear the area where you’ll be installing the garden edging. Remove any existing grass, plants, or debris. Ensure that the ground is level and even.

Mark the edging line

Use a string to mark the desired line for your garden edging. This will serve as a guide when installing the treated pine boards.

Dig a trench

Dig a trench along the marked line, making it slightly wider and deeper than the thickness of the pine boards. The trench should accommodate the boards and provide stability.

Install the pine boards

Place the treated pine boards into the trench, one by one, ensuring they fit snugly. If you’re using multiple boards, overlap them slightly to create a seamless look. Use a level to make sure the boards are straight and even. If necessary, trim the boards to the desired length using a saw.

Secure the boards

Once the boards are in place, secure them to the ground using long galvanised nails or landscaping spikes. Drive the nails through the boards into the ground, ensuring a firm hold.

Backfill and level

Fill the trench behind the installed pine boards with soil, packing it tightly to provide stability. Use a tamper or the back of a shovel to compact the soil and create a level surface.

Finishing touches

To enhance the appearance and durability of the garden edging, you can apply a protective sealant or stain to the treated pine boards. This will help protect them from moisture and extend their lifespan.

Maintain and care

Regularly inspect the garden edging for any signs of damage or deterioration. Replace any boards that have become damaged over time. Also, ensure that the area behind the edging remains weed-free and well-maintained.

Remember to follow all safety guidelines when working with treated pine and use appropriate protective gear such as gloves and safety glasses.
