preparation for seed

I compared several preparation plans to plant new seed. I used Pennington Smart Seed Sun and Shade, which contains 65 percent perennial rye. I used a teaspoon of seed--about one-third gram. It was sown on squares 12 inches by 12 inches. The soil was mostly sandy loam and bare due to heavy shade. Weather was rainy, supplemented by irrigation. Temperature began at 67 with nights in the 50's. Tallest sprouts were about 1 inch tall on day 11.

Seedbed Preparation Sprouts on Day 11
none 8
seed raked-in 200 (estimated)
seed under clippings 26
seed on top of clippings 43
raked then seeded 60

I will try to get photos when the new grass is more visible.
The grass fresh clippings used appeared to be disturbed--moved around-- perhaps by squirrels or rain. A few leaves are falling now; blown off a few times per week.

Clearly, sown seed, followed by raking-in resulted in the best "take" so far.

I seeded and then aerated my lawns this year and I have seen much better germination than in years past

We've have a few good days of rain and maybe folks are watering more.

So, what is the take-home message here?

It looks like you illustrated the age-old talking point of the necessity of seed-to-soil contact for optimal germination.

How do you see this information being used by others on this forum?

The take home message for me is that seed DOES germinate in and amongst grass clippings when sown merely on the surface... Large areas of thin grass and bare spots are not usually cost effective to work seed into the turf...

The fact that germination has already started with this group is encouraging and there is also the "Dormant" process yet to come for the seed not yet germinated... All that was done was broadcasting, therefore,,, very cost effective...
