About 50% of our lot was thick with mostly pine trees under which was
left as a natural area. We just had many of the pines removed leaving
some large open natural areas full of pine needles, leaves and big
mounds of pine mulch from the stump grinding.

We plan to do a lot of landscaping and put in a garden now that we get
enough sunlight to grow more than just mushrooms and moss. But I'm
wondering what the best first step is to convert the natural areas to
productive gardening soil. My wife thinks we should just spread out the
mounds of pine mulch and mix it with the natural debris. But I'm
worried that all the pine needles will leave a soil that is much too
acidic. I'm thinking we should rake up all the pine needles first.

What is the best way to turn a natural area into a gardening area? I
would appreciate any advice or pointers to information about what to do
in a situation like this.
