2. Determine the Size and Shape

Determine the size and shape of your raised beds based on your garden needs and space limitations. Popular sizes are 4'x4', 4'x8', and 3'x6'. The height can range from 6 inches to 2 feet, depending on your preference.

3. Gather Your Materials

Gather your materials, including untreated wood planks, galvanized screws, a saw, a drill, a level, a measuring tape, and weed barrier fabric.

There is one important thing you should consider to have better longevity and durability is choosing the main material for your raised beds. Galvanized raised garden beds will be more durable than others such as wood, vinyl, fabric, etc… but it is not affordable.

4. Build the Frame

Cut the wood planks to the desired length and assemble them into a frame using galvanized screws to secure the corners. Make sure the frame is level by using a level tool. If you're building a larger bed, add support beams in the middle to prevent bowing.

5. Add Weed Barrier Fabric

Lay down weed barrier fabric on the ground inside the frame to prevent weeds from growing up into your raised bed. Cut the fabric to size and staple it to the sides of the frame.

6. Add Soil, Compost, and Worm Castings

Fill the bottom third of the bed with a mixture of topsoil, compost or composted manure. You can also add worm castings, which are especially beneficial.

What are worm castings? Worm castings, also known as vermicompost, are the nutrient-dense waste material worms excrete as they break down organic matter in their digestive systems.

Add layers of the soil, compost, and worm castings until you reach the top of the bed, watering thoroughly after each layer.

For the final layer, fill with a soil, compost, and worm-casting mixture up to 2 inches from the top. This will allow room for the soil to settle and provide space for watering the plants.

The worm castings will help enrich the soil as their high nutrient content and crumbly texture promote plant growth and healthy soil life. Be sure to thoroughly incorporate the castings throughout the soil profile.
