By Abigail

Transform your garden into a neat and organized space with timber garden edging. Not only does it enhance your garden's aesthetics, but it also helps contain soil and prevent weeds from spreading. In this guide, we'll walk you through the process of installing timber garden edging, using products readily available at Bunnings. Let's get started!

What You'll Need

Before you begin, ensure you have the following materials and tools:

  • Timber garden edging (e.g., treated pine or hardwood)
  • Tape measure
  • Spirit level
  • Shovel
  • Hammer
  • Galvanized nails or screws
  • Gloves and safety glasses

Preparation

Before you start digging, plan your edging layout. Consider the shape and size of your garden beds, as well as any existing features like plants or paths. Mark out the edging line using stakes and string.

Choosing the Right Timber

Bunnings offers a range of timber garden edging options. Treated pine is a popular choice due to its durability and affordability, while hardwood provides a more premium look and longer lifespan. Ensure the timber is suitable for outdoor use and has been treated to resist rot and decay.

Installing the Edging

Now that you've prepared the site and chosen your timber, it's time to install the edging. Follow these steps for a professional finish:

Step 1: Dig the Trench

Using your shovel, dig a trench along the marked line, about 200mm deep and 100mm wide. Ensure the trench is straight and level using your spirit level.

Step 2: Lay the Base

Create a flat, stable base for your edging by filling the trench with a layer of compacted sand or gravel. This helps prevent the edging from wobbling or rotting over time.

Step 3: Install the Edging

Starting at a corner or straight edge, lay the first piece of timber in the trench. Ensure it's level and flush with the ground. Secure it in place using galvanized nails or screws, spacing them evenly along the timber.

Continue laying the edging, ensuring each piece is level and butts up against the previous one. Use a mitre box to cut precise angles for corners and curves. If you're using interlocking edging, follow the manufacturer's instructions for assembly.

Step 4: Backfill and Compact

Once the edging is installed, fill the trench behind it with soil, compacting it firmly to provide additional support. Ensure the edging remains level as you backfill.

Maintenance and Care

With proper care, your timber garden edging will last for many years. Regularly inspect the edging for signs of damage or rot, and treat any affected areas promptly. Keep the edging clean by removing debris and weeds that may accumulate over time.

For a long-lasting finish, consider applying a timber preservative or sealant. This will help protect the edging from the elements and maintain its appearance. Always follow the manufacturer's instructions when applying any timber treatment.

By following this guide, you'll have your timber garden edging installed in no time, transforming your garden into a neat and inviting space. Happy gardening!
