That has worked for me in the past to some degree in partial shade areas but in full sun, around here it’s all dead by 4th of July like clockwork. Often even semi-shaded areas cook. Just gets too hot here for turf that young. Would work better the farther North you go but still seems risky unless you have plenty of seed to spare and willing to take a chance.It is amazing. Someone agrees with the concept of winter seeding of grass. See Dr. Brillman's article.
I think for a real test, you would need to compare coverage and density at 6 months and then a year. Sprouting vs not sprouting of new plants is important, but I think to really compare methods, there would need to be a comparison of actual results in terms of survival and vigor. For a true “scientific” test with a control and accounting for annual variables, it would be hard to do.This is an almost impossible question to answer.
How do you compare seeding methods in an overseed situation?
Do you count the new grass sprouts after 4 weeks?
How does one compare preparation methods?
Cut short? Power rake? Topdress with soil? Slit seed? Aeration (or double aeration)?
Topdress with peat moss?
How do you count the new grass sprouts--among the old grass sprouts?
Plant wide-blade K-31(easy to spot)?
Plant blue fescue?
Plant a yellowish annual rye?
Who would want to count 250 grass seed sprouts on one square foot?
