1. I built my raised bed frame out of two 2x8s @ 12 feet long and two 2x8s @ 4 feet long. I simply screwed them together with 3-1/2" long exterior grade screws. I use 3 screws per corner and make sure they are centered in the board you are going into the long way. I drew red lines on the photo (below) to show where the screws are.
*As for the type of wood, I used cheap natural spruce boards but you could also used cedar or something. Spruce is known to rotationally fairly quickly so I will have to replace boards as needed, but I would NEVER use pressure treated wood in the vegetable garden because of the chemicals they treat the wood with.
2. Backfill with good soil.
3. For the hoops, I used 3/4" galvanized conduit and bent it 180 degrees at approximately a 4 foot diameter. I placed them every 4 feet along the raised bed and used conduit mounts to fasten them in place with 1-1/4" screws as seen below:
4. I covered it with 6mil clear plastic. A 12'x25' piece was more than enough, but not enough to make two. The corners can be a little tricky, so I took the slack at the corners I rolled it up tightly and clamped it in place. I used 2" spring clamps.
This is how I built mine and I would love to hear how you built yours.
Thanks for reading!
