Pine bark nuggets are naturally buoyant and will float in circumstances with too much water. Any organic mulch benefits soil and plants by retaining moisture, protecting plants from extreme cold or heat and preventing the spread of soil borne diseases. This is true of pine bark mulch as well.
Beside this, where can I use pine bark mulch?
Pine bark mulch, when applied several inches deep, helps retain soil and keeps it from eroding into the surrounding areas. This is helpful for areas of plain dirt with sporadic plants, such as border gardens along fences, around tree trunks and throughout gardens.
Accordingly, is pine bark mulch toxic?
Toxic pine bark mulch is dangerous for plants. To ensure your pine bark is healthy, cut it from a healthy tree, and apply it while still fresh. If old pine bark develops a foul smell, spread it in an area away from plants to expose it to air. Water it to rid it of toxins.
Bark nuggets are very similar to the chunks, they are slightly smaller and less expensive. Since the nuggets are smaller they can be misplaced and blown away much easier than the chunks. This will require you to replenish it more often. The shredded bark is generally the most inexpensive form of mulch.
