The debate has waged on for many years regarding the acidity of pine straw (also commonly called pine needles and pine straw mulch) and the effects that potential acidity may have on soil acidity and subsequent plant health when used as a mulch. It's stated in numerous places that pine straw is acidic, it will turn your soil acidic, and only plants that like acidic soil can be grown with pine straw as mulch. Users of pine straw mulch know this is not true and have the gardens to prove it. The owner of Pine Straw Info has performed extensive testing to separate the fact from the fiction in that argument. The results of his testing and research are revealing and important for all gardeners and landscapers that want to grow superior plants.
