| If grass seed needs soil contact, to germinate more effectively, why can't you mix the seed with soil and THEN apply? (With a drop spreader for over seeding lawns.) |
| Well, technically you could. But, you would have no control over whether or not the grass seed would be buried too deeply. The seeds need to be on top of the soil, not buried in it because the seeds need light in order to germinate. Some seeds will germinate in the dark and can be buried in the soil. The rule of thumb is to bury seeds twice as deep as the diameter of the seed. Grass seeds are long, but they are only a hundred's of an inch in diameter. Bean seeds, on the other hand, can be buried an inch deep into the soil. Hope this explains things! |
