I have a three-four acre tract that has about 30 pecan trees growing. These were contributed by squirrels and crows. Right now the trees are about 8 yrs old, and someone told me that I should look into caring for them since I have an orchard for all intents and purposes....that in a few years, they could be very profitable. Does anyone have any advice about these trees (or links)? I thought about pecans, but I also thought about pecan wood.
