I just laid down 1/2 pound of Bio-Pack over my lawn. It says 1/2 pund will do 10,000 sq/ft. I used a miracle grow spray bottle that goes on the ned of a hose and kept walking around. It took well over an hour to spread this over 3,000 sq/ft. I also gave my Woody Ornamentals and Perennials a soil drench with 2 TBS per 1 gallon of water. I will reapply in the spring at the rate 4 TBS per gallon of water in a watering can and just walk around the yard. If I have uneven coverage, no big deal as these little organisms/bacteria/fungi will find their way through the soil and reproduce.
