I live in Michigan and want to construct a raised garden in only location
in yard where I get enough sun. this will be about 500 sq ft area. Need to
raise because of poor drainage. I picked up some treated 2x10's for this
project, and some 4x4's I was planning to cement into ground and nail
together. My neighbor advised me that frost would likely force the cemented
4x4 posts up. He said to use crushed rock and not cement. any advise

IMO- that's *way* too big for a raised bed. 9" isn't going to help
a lot on the drainage. You'd make your life easier by running drain
tiles and landscaping.
Raised beds also help on the back, though. Raise the beds up 18-24"
& your back will thank you. Cut the 4x4s to the height of the beds
- make the beds about 3-4'x8' & plop them right on top of the ground.
My brother & I threw together a cedar 4x8 bed for my dad a couple yrs
ago when he broke his hip. His old garden is probably 20x40--- now
he plants all his greens, beans & salad fixin's in the raised bed. 4x8
x 24"high. We used 1" boards for the sides - a stringer in the
center- and nailed it with ring-shank nails. It has survived 3 NY
winters without showing signs of wear.
DONT USED TREATED LUMBER FOR VEGETABLES GARDENS.
Although they claim its safe they said that same thing about the old
chemicals now banned!
If it kills the nasties that lead to wood rot, can it be good for
So, everything that kills stuff is an antibiotic?
Wow, I've wasted a lot of money over the years.
If you're concerned about the treated wood leaching chemicals into the
soil, line the raised planter walls with plastic.
I think Bob has a good point. That's why we used cedar- but cypress
or redwood would work. Call a local mill for the best prices--
you don't need kiln dried or dressed lumber- and D grade is fine to
just hold the dirt in.
Our local yard carries 1x12 red cedar, dressed one side, that is
called D, but I've gotten some boards that the borg would have called
'select'. It is about the same price per board foot as PT.
The reason redwood and cedar are effective is that the wood itself contains
substances incompatible with animal life. If it kills bugs, can it be
harmless to humans?
Answer: Sure. No human ever died, or even got sick, from DDT.
Granted that is an extreme case, but you said never got sick from

Check out the links at the bottom if you are interested in learning
and aren't worried about your ego being threatened by finding out your
opinion no this matter is worthless.
If you thought about it even a little, you'd realize that the
mechanism by which DDT operates is to interfere with reproduction.
Since we are all organic based life forms on this planet (I'm giving
you the benefit of the doubt), we tend to share similar 'weaknesses'
towards certain chemical.
Again, do some research - it'll pay off in the long run.
This is a paper on a father-son team who mistook DDT for flour when frying
fish. The paper did not rule out poisonous fish as the cause of their
malady, so I'd say the conclusions were equivocal. The paper also did not
rule out inherited stupidity that obviously runs in that family.
Let's look at the statements in the Wikipedia site:
* "This endocrine disrupting activity has been observed toxicological
studies involving MICE and RATS..."
* "... exposure to DDT at amounts that would be needed in malaria control
MIGHT cause preterm birth and early weaning..."
* "...studies SUGGEST that DDT exposure is a risk FACTOR for premature birth
and low birth weight..."
* "...SUGGESTS children who have been exposed to DDT while in the womb have
a greater CHANCE of experiencing development problems..."
* "...documented decreases in semen quality..." [not death]
* "...daughters of highly exposed women MAY have more difficulty getting
pregnant..." [but not die]
* "DDT exposure is ASSOCIATED with early pregnancy loss, a type of
* "... in utero DDT exposure MAY affect thyroid hormone levels and [MAY]
"play an important role in the incidence and/or causation of cretinism."
[but not death]
* "DDT is SUSPECTED to cause cancer..." [but not death directly]
And so on.
If what you've found is an example research "paying off," you need to get
your money back.
Bottom Line: No human every died, or even got sick, from DDT (excepting,
maybe, two who can't tell the difference between a weather ballon and
As per your recommendation, I did check the first seven (of 117) references.
No deaths attributable to DDT.
As to your advice about whether I should worry about my ego being
threatened, I SUGGEST that potential damage to my ego is considerably less
debilitating than your predicament. To see the shrine of Silent Spring
turned into a Cargo Cult airplane and realize your golden idol is tarnished
must be wrenching beyond measure.
Are you trying to garden or deal with poor drainage?
Also, thats too big. In a case like that, you just bring in dump trucks of
topsoil and then build a retainer wall to hold it in. Due to the size, wood
Not recommended for food gardens.
What you can so though is something like what I have which is raised
'pallets'. I have a bad back and like to have a garden but can't do the
ground level work.
Using PT wood (2x8) and 4x4 for the legs, we put 3 panels (18 inches across)
and raised them 1 ft then ontop of that I have terra cotta looking tall
'tree containers' lined up. I have 8 feet of this now with plans for
another 16 along the back of the house. Got wild flowers for cutting,
carrots, chives, lettuce, tomatoes, squash, bell peppers, catnip,
strawberries, and things like that already going in other containers on a
shorter raised table.
