If your soil is feeling weighed down and compacted, I’m here for you! I come from decomposed tree and plant matter in boggy areas. I’m very light and airy – an excellent addition to any heavy soil. I’m acidic, which means plants like rhododendrons, azaleas, hydrangeas and ferns love me! And I’m black (hence the name) so I add great visual appeal! Some people use me for top-dressing lawns, but I recommend my side-kick, top dressing, for that.
