The formed densified organic material is made by drying a loose mixture of mulch material and compressing the loose mixture of mulch material into a formed densified organic material. The method of apply includes: placing formed densified organic mulch on the ground at spaced locations; adding moisture to the densified organic mulch, allowing the densified organic mulch to absorb the moisture, causing the densified organic mulch to expand and reconstitute back into its original state of loose mulch; and spreading the loose mulch as required. The formed densified organic material has a moisture content of less than approximately 20 percent, a density greater than approximately 40 pounds per cubic foot, and a weigh less than approximately 5 pounds. ## Claims ### Claim 1 A method of making a formed densified landscape mulch, the method comprising: mixing shredded wood with other organic material to form a formulated mixture; drying the formulated mixture; compressing the formulated mixture into the formed densified landscape mulch; wherein for every one inch per square foot of mulch thickness desired when the formed densified landscape mulch is applied, approximately one pound of formulated mixture is dried and compressed. ### Claim 2 (depends on 1) The method as recited in claim 1 wherein the formulated mixture is dried such that the formed densified landscape mulch has a moisture content of less than 20 percent and the formed densified landscape mulch is compressed to greater than approximately 40 pounds per cubic foot. ### Claim 3 (depends on 2) The method as recited in claim 2 wherein the formulated mixture is dried such that the formed densified landscape mulch has moisture content of between approximately 4 percent to approximately 19 percent and the formed densified landscape mulch is compressed to between approximately 45 pounds per cubic foot to approximately 65 pounds per cubic foot. ### Claim 4 (depends on 3) The method as recited in claim 3 wherein the formulated mixture is dried such that the formed densified landscape mulch has moisture content of between approximately 8 percent to approximately 15 percent and the formed densified landscape mulch is compressed to between approximately 50 pounds per cubic foot to approximately 60 pounds per cubic foot. ### Claim 5 (depends on 1) The method as recited in claim 1 wherein lignin provided in the mulch material will provide cohesion when the formulated mixture is compressed into the formed densified landscape mulch. ### Claim 6 (depends on 1) The method as recited in claim 1 wherein the formed densified landscape mulch is formed into a briquette, square or cylinder. ### Claim 7 (depends on 1) The method as recited in claim 1 wherein additives containing fertilizer, seed or weed control are added to the formulated mixture prior to compressing the formulated mixture of mulch material into the formed densified landscape mulch. ### Claim 8 A formed densified landscape mulch comprising a moisture content of less than approximately 20 percent, a density greater than approximately 40 pounds per cubic foot, a weigh less than approximately 5 pounds, and approximately one pound of a dried and compressed formulated mixture for every one inch of mulch thickness desired when the formed densified landscape mulch is applied and moistened. ### Claim 9 (depends on 8) The formed densified landscape mulch as recited in claim 8 wherein the moisture content is between approximately 4 percent to approximately 19 percent. ### Claim 10 (depends on 9) The formed densified landscape mulch as recited in claim 9 wherein the moisture content is between approximately 8 percent to approximately 15 percent. ### Claim 11 (depends on 8) The formed densified landscape mulch as recited in claim 8 wherein the density is between approximately 45 pounds per cubic foot to approximately 65 pounds per cubic foot. ### Claim 12 (depends on 11) The formed densified landscape mulch as recited in claim 11 wherein the density is between approximately 50 pounds per cubic foot to approximately 60 pounds per cubic foot. ### Claim 13 (depends on 8) The formed densified landscape mulch as recited in claim 8 wherein the weight is between approximately 1 pound to approximately 3 pounds. ### Claim 14 (depends on 13) The formed densified landscape mulch as recited in claim 13 wherein the weight is between approximately 1.25 pounds to approximately 2.5 pounds. ### Claim 15 (depends on 8) The formed densified landscape mulch as recited in claim 8 wherein the formed densified landscape mulch is a briquette, square or cylinder. ### Claim 16 (depends on 8) The formed densified landscape mulch as recited in claim 8 wherein additives containing fertilizer, seed or weed control are distributed through the formed densified landscape mulch. ### Claim 17 A method of apply mulch to a landscape, the method comprising: placing formed densified organic mulch on the ground at spaced locations; adding moisture to the densified organic mulch, allowing the densified organic mulch to absorb the moisture, causing the densified organic mulch to expand and reconstitute back into its original state of loose mulch; and spreading the loose mulch as required. ### Claim 18 (depends on 17) The method as recited in claim 17 wherein additives such as fertilizer, seed or weed control are distributed through the densified organic mulch, the additives being spread when the loose mulch. ### Claim 19 (depends on 17) The method as recited in claim 17 wherein the densified organic mulch has a moisture content of less than 20 percent. ### Claim 20 (depends on 17) The method as recited in claim 17 wherein the densified organic mulch has a density greater than approximately 40 pounds per cubic foot. ### Claim 21 (depends on 17) The method as recited in claim 17 wherein the densified organic mulch has a weigh less than approximately 5 pounds.
