A proper seedbed is firm and free of competing vegetation. Correct firmness is when an adult footprint is only slightly visible on prepared bed prior to the seeding operation. A firm seedbed is essential for proper seeding depth. Most species should be planted at a shallow depth of 1/4 to 1/2 an inch. Larger seeds can be planted up to 1 inch deep. Most seedings are too deep if you cannot see a few seeds on the soil surface.
