I have recently re located to a site with a small pine forest on the north side of my field. After just assuming that pine needles for mulch added acidity to the soil, I decided to research it. To my delight I have found that there is no real effect on the acidity levels of soil mulched in pine straw, in fact, they help to maintain around a 6.5 ph level. My next concern were the terpines found in the needles that deter germination...it turns out that after they have browned, and the pine scent is gone, so are the terpines. I have began to mulch my veg garden with them and love working with it as a mulch...mainly because 10 minutes of raking results in a pile perfect for a 30'x30" bed. Now, what I would like is to hear from you all about whether or not my research has mis-leaded me or guided me into a really great solution to all my mulch needs! I so respect this community and your opinions, wisdom and experience have become such a valued asset...thanks again!
