Mini Chunk Bark
This is also called nugget bark. The pieces are about the size a quarter. It stays put in windy, hilly areas. The larger pieces take longer to decompose. This is one of the longer lasting and most durable bark.
Using mulches and barks as a cover for landscaping, discourages weeds and helps in moisture retention. A 2-4" application is standard for most coverage needs, it is recommended to replenish this each year.
