No sign of germination of fall or winter seeded tests so far (except for the November seeded sample--which is about an inch tall). It is 36 degrees here at the moment.
We expect crabgrass germination about late May or Early June, after dandelion bloom and about the time of the fourth mowing. Perhaps three weeks after last frost. Our last frost is about May 5th. Pardon me if I disagree with myself from time to time.
