How to Fill a Deep Raised Bed for Cheap: A Step-by-Step Guide

In recent years, raised beds have become increasingly popular among gardeners due to their ease of use and efficient drainage. When it comes to deep raised beds, filling them can be costly, but it doesn’t have to be. By using logs and organic matter as base layers, you can save money while promoting better drainage and moisture retention. Here’s a comprehensive how-to guide designed to help you create a thriving garden bed without breaking the bank.

Materials You Will Need

  • Logs (any type of untreated wood)
  • Organic matter (leaves, grass clippings, or compost)
  • Good quality soil

Step 1: Laying the Foundation with Logs

The first step in filling your raised bed is to create a strong foundation.

  1. Collect logs or large branches. Make sure they are untreated to avoid any chemicals leaching into the soil.
  2. Arrange the logs at the bottom of your raised bed. Cover the entire base evenly to create a stable foundation.

Using logs not only saves money but also helps in creating air pockets that promote better drainage.

Step 2: Adding Organic Matter

Once your foundation is set, the next layer involves organic materials.

  1. Gather organic matter such as leaves, grass clippings, or kitchen scraps.
  2. Spread the organic matter over the logs. This layer will slowly decompose, enriching the soil with nutrients.

The organic layer enhances moisture retention, which is crucial for plant growth.

Step 3: Filling with Soil

To complete the bed, fill the remaining space with high-quality soil.

  1. Choose good quality soil that suits the type of plants you intend to grow.
  2. Fill the raised bed with the soil, spreading it evenly over the organic matter.

Proper soil ensures that your plants receive the nutrients they need to thrive.

Expert Tips

  • Mixing soil types: Consider adding some compost to your topsoil for additional nutrients.
  • Watering: Initially, water the layers well to help them settle and compact.
  • Plant compatibility: Plan your garden layout beforehand to ensure compatibility of plants sharing the space.


Filling a deep raised bed is an investment in your garden’s future. By using logs and organic matter as foundational layers, you not only cut costs but also create an environment that fosters strong plant growth. Remember, much like building a house, a strong foundation ensures the longevity and stability of your garden. Happy gardening!
