Ok you asked for it!
The good thing about raised beds is that even if you have lousey soil, or no soil in some cases like a concrete yard... this will make gardening easy. Especially for old folks who don't want to be on their knees or bed over a lot. I built this box a little higher than you really need so that I would be able to reach all over the place with it. Once you fill it with soil mix, it will provide the excellent drainage needed to grow picture pperfect vegetables and flowers most of the year!
You can build the basic raised bed in a few hours, then add versatility by mounting PVC pipes inside to hold hoops that elevate bird netting, or in colder weather plain old plastic to either start the seedlings early or just cover the crops for better production, sort of like a mini greenhouse.
For best results orient your bed north-south for maximum sun exposure.
It is preferable to use redwood or cedar ― both are beautiful and rot-resistant. But here in Mexico, most likely you can only get Pine, there are some regional woods that also are rot-resitant,so ask your local lumber monger.
You’ll need a table or power saw to cut the wood; after cutting, paint the wood on all sides with an oil-based sealer or stain or left over deck sealer, almost anything will work. I would not use house paint since you don't know what stuff is in that. I chose to paint it a redwood color stain.
The first box I built was only 12 inches high, as shown on the photos. the 2nd one I
doubled it, to be 24 inch high. I personally like the bigger box because I do not have to lean over or ben
d over as much. The downside is that you will use twice as much wood, screws, and soil mix. You can start with the shallow box first and see how you like it, then change it. The construction is simple and you can adjust the size to fit your particular space and requirements.
An electric drill is helpful, though not required.Stuff you will need:
One 6-foot-long 4-by-4
6, 8 foot long 2x6's
1 10ft long 1 inch PVC water pipe
2 10ft long 1/2 ich PVC pipes
1/2 gallon semitransparent exterioir oil stain
32 3 1/2 inch #14 wood screws
16 1/2 inch #8 wood screws
1 roll of 1/4 inch mesh hardware cloth. total of 4x10ft
If you are putting this on top of concrete you do not need the hardware cloth
I used it because I didn't want mole, gophers, rats and other things digging into
8 1 inch conduit straps
32 cubic feet of soil or mix.
