Cover the seeded area with cheese cloth. Lay the cheese cloth directly over the seeded areas, but don’t pull the cloth tight. Leave the cloth loose.
Secure the corners of the cheese cloth with sticks or dowels. Pound the dowels or sticks into the ground about 1 to 2 inches so they hold the cheese cloth in place.
Keep the grass seed moist by watering the cheese cloth. The moisture will soak through the cloth to the seeds.
Remove the cheese cloth after you see seedlings pushing up on the cloth.
Use your hands to apply 1/8 to 1/4 inch of humus over the newly sown grass seed. You can use sawdust or peat moss, which not only will hide the seed from the pigeons, but it will help retain the moisture needed for germination.
Continue watering the humus and grass seed according to the directions for the specific grass seed you are using.
Leave the humus in place after the seedlings appear. The humus will decay and disappear as the grass blades grow longer.
