Question - can you use pine needles as mulch ? for flowers ? vegetables ? Thanks,
Pine needle mulch is especially good for acid-loving plants, such as rhododendrons, azaleas, blueberries, tomatoes, onions, and garlic. But it only acidifies the soil a tiny bit (some gardeners have found no change in pH after many years of using it), so other plants can benefit from it, too, such as annual flowers. It breaks down slowly.
