    Prefer to put the seed under the compost or on top and raked in. or both?

    The lawn is aerated and ready to be top dressed. I was thinking of throwing down some seed now to fall into the aeration holes and then put down some more once I get the 1/2" of top dress put down just to be safe.

    Will the seeds germinate without direct sunlight just from the warm soil temps?

    seed should be no deeper than 1/4". ( under soil.)

    I only put seed on top. I never rake it in or bury it in ANY way.

    I have been told that you should seed than topdress.
    The seed needs direct contact with the minerals in the soil to grow.
    Compost on top holds it in place hides it from the birds will hold the moisture but and keept the soil warm.

    Depends on what is covering it and how deep. I like a layer of compost over the seed for all the reasons mentioned.

    1/2" of topsoil I would rake it in after seeding - depending on how thick the present grass is. Areas with lots of blades sticking through shouldn't need any raking, as mn said.

    You may bury the seed too deep in the holes if you put it down first. If you do it after be sure to drag or sweep the seed in and not leave it on top to become bird food. Yes the seeds will germinate with out direct sunlight but they must be close enough to the top to reach sunlight in a day or so. Unless you are putting down a huge amount of topdressing you will not bury them too deep except in the holes. You can make a drag out a piece of chain link fence that works good for this job.

    I sure have - last year (spring) I put down some Rebel IV TTTF and I had birds that I'd never seen before hanging out at my house. Once the seed (what was left) germinated, the birds were nowhere to be found.
