Why do you want to raise the bed? Will 4 inches be enough for what you are
wanting to accomplish?

I raise mine to prevent root crops from rotting if we get too much rain.
Most radishes would only require 4 inches. Potatoes will require more. I
till my soil, then rake the dirt together from two directions to make a
ridge. I make the ridge as high as I need ( 4 to 10 inches) for what I am
planning to plant on it, then take a rake and flatten and level off the top.
Then I lay a soaker hose along the top of the ridge and plant along the
hose. I make the top of the ridge wider for onions, radishes, and carrots,
and plant them on both sides of the soaker hose. If you cant locate a
manufactured soaker hose, you can take a regular watering hose, make very
small holes in it, install a water pressure regulator, cap the end and it
will do the job.

How high should a raised bed be?

One source says to use scaffold boards, but I have no idea where one gets
scaffold boards from, should they be treated to stop rot?

Do they really have to be that high?

Would 4 inches be high enough?
