Build a Simple 4×8 Wooden Raised Bed to grow your own vegetables

The easiest way to build a raised bed- attach 4 boards together and fashion a 4 foot by 8 foot rectangular garden bed.  This size garden bed is large enough to grow many crops over 2-3 seasons in New England and is incredibly simple to build.  I bought untreated pine boards from Lowes to keep costs low and to eliminate the possibility of chemical contaminants.

Materials needed to build this very simple bed:

  • 2  2x12x8 in. untreated pine boards
  • 2  2x12x4 in. untreated pine boards
  • 4  2x12x4 for interior corner braces (not pictured below)
  • 1  carpenter’s square
  • drill
  • 12 exterior screws, at least 4″ long
  • rake
  • shovel
  • 32 square feet of soil, (ideally 16 compost, 8 vermiculite, 8 peat moss)
  • *Optional:
    •  4×8 hardware cloth,
    • heavy duty stapler
    • wirecutters to cut off any excess hardware cloth

Square, screws, impact driver, foot. Foot not necessary.


Using the square to put two pieces of wood together at a 90 degree angle


75% of the way there


Drilling in the screw- I pre-drilled holes using a drill bit slightly smaller than the diameter of the screw.  


Three screws at each corner of the bed


Prior to building the bed, I dug about 12-18 inches into the rocky soil. I did my best to loosen the soil (it was highly compacted from tree-removal vehicles) and removing many rocks, the bed was ready to fill.


I filled the bed with a mix of compost and loam. I added additional sifted compost that was made here last year.


Raking the bed flat

Because the bed is built from untreated pine, it will likely last a few years and then need to be replaced.  It may also warp on the sooner side, as it is just 4 boards screwed together. Oh well.

This particular bed is located within a fenced area, on top of garden soil.  If I were to construct the bed in a more open, unfenced area, I would do several things differently.

  • Staple hardware cloth to the bottom of the bed prior to filling it with soil. Hardware cloth is not fabric, but a metal fencing-type material with square openings 1/2″ in size.  Putting this on the bottom of the bed prevents small rodents from tunneling through the bottom of the bed.  It can also prevent roots and rocks from migrating through the soil into the bed.  Finally, it helps to contain the soil you place in the bed.
  • I would add a different mix of soil ingredients into the bed.  In his book, Square Foot Gardening, Mel Bartholomew suggests a mix of:  1 part peat moss, 1 part vermiculite and 2 parts high quality compost.  This is a super mix and makes the soil light, fluffy, friable and super easy to work with.  I did not do this because I have chosen to amend the beds at the farm with leaf mulch and other compost I produce over the coming years.
  • Add a small fence around your bed.  You know how much YOU love fresh veggies? Groundhogs, rabbits and deer love them more.  Nothing is sadder than returning home from a hard day of teaching to see the groundhog inside the garden eating the last broccoli plant that you have been tending to for months.  This happened to me.  I know, shocking.  This was the day I found out that if you chase a groundhog and bark like a dog, the groundhog will show you its fence climbing skills.  6 foot fence scaled by this brown furry creature.  What a show-off.
