Step by step directions on how to build a garden box for a raised bed garden. Save money by making your own garden beds. Perfect for square foot gardens.

Building a wood box is a great way to save money.  You can get wood from many different places.  If you find a builder a lot of time they have scrap wood you can take and make boxes out of.  You can also buy the wood at a local hardware store.

Each box needs to be at least 12 inches deep. For the bottom, you can use any material that you can put holes in or already has holes in it so the water stays in the soil but doesn’t pool and flood the roots.

How To Build A Garden Box

Here is the step by step instructions on how to make the box:

Cut wood for the raised bed garden box

1. Measure and cut your wood to the size you want it to be.  I made my boxes 2 ft by 4 ft.  So I cut my wood to make that size of a box.  But you can make a box whatever size works for your space.

2.  Make the box by lining up the wood on a flat surface.

Tip: Use a wall or some other solid surface to hold the wood in place and so you can up pressure on the wood when drilling

3. Drill holes in the wood for the screws.  Make sure the holes are drilled into both pieces of wood in the places you want them.

4. Drill Screws into the holes you made

5. Repeat until all sides have screws in places.

6. If adding a bottom, screw bottom onto the box (our box doesn’t have a bottom since it is on dirt that the roots can grow into.) Make sure there are drainage holes in the bottom.

7. Place box where you want it to be and fill with soil.

It is easy to build a garden box and make your own garden.  The best part is when you get to reap the rewards of your work when you make your meals with the food from the plants!

  2. You said the size of the boards but did not say what kind of wood the boards were. Are they treated wood? Do you use any kind of support in the middle of the boards?

    1. You can use treated and non-treated wood, that is up to you. We didn’t put any supports on the boards. We didn’t need them. If you are going to stack them to make them higher you may want supports. We just got the boards at lowes and used untreated wood. If you are looking for more organic gardening, I would use untreated for sure.

        Can you grow the same amount of vegetables in a 2×4 boxes as in 4×4 boxes.

        1. It depends on the type of vegetables you grow. But as a general rule no, you can not. The extra 2 feet of growing space means more space for plant growth and a variety of plants.
