10 Easy Steps on How to Build a Raised Garden Bed With Composite Decking

Step 1. Measure the Area:

Measure the area where you’d like to build your raised garden bed and ensure it is level. It’s important to ensure your measurements are accurate, so your bed has a flat surface. Use a leveler to ensure the area is even if you need to.

To keep everything nice and secure, use either screws or nails, depending on how many boards you’re using. There are lots of different ways to do this, so feel free to get creative and make your bed as unique as you’d like.

Step 4. Add Soil:

Step 6. Add Mulch:

Mulch is an important part of any raised garden bed, and it helps keep weeds down while also retaining moisture in the soil. Spread a layer of mulch over the top of your plants to help keep them healthy. It will also give your raised garden bed a finished and polished look.

Step 7. Add Decorative Elements:

Now it’s time to make your garden look even more beautiful by adding some decorative elements such as rocks, pebbles, or wood chips. These will give your garden bed texture and color, drawing the eye and creating a peaceful atmosphere.

Finally, you may want to add some extra features to your raised garden bed, such as lights or a trellis.

  3. To secure the boards in place, use galvanized screws and washers for extra strength and durability.
  4. For added protection against pests, line the bottom of your raised garden bed with a hardware cloth before filling it with soil.

5 Things You Should Avoid

  1. Avoid using composite decking screws as they don’t provide enough adherence to the boards.
  2. Avoid using composite boards that are too thin, as this could cause warping or cracking over time if not properly supported.
  3. Avoid stacking the boards too close together, as this can make it difficult for water and air to circulate in the bed.
  4. Avoid using composite boards with a hollow core, as these may be more susceptible to breakage and cracking due to uneven weight distribution within the bed.
  5. Avoid positioning your raised garden bed in an area that receives direct sunlight for extended periods of time during the day, as this can cause the boards to warp or crack. Doing so could also cause your vegetables to become sunburned and, in turn, reduce their quality.

By following these simple tips when building your raised garden bed with composite decking, you’ll be able to ensure that it is built safely and properly without experiencing any long-term issues or complications. With the right materials and tools, your raised garden bed will be able to provide you with the perfect environment for your vegetables to thrive.
