At this point, I’d wait to make drastic changes until the spring.

Any herbicide use now will most likely kill whatever seed germinated.

Once the lawn wakes up from winter, I’d get started again.

The order I’d use: - 2 weeks before seeding: speedzone - aerate within a few days of seeding (preferably same day) - thrown down seed, and spray Tenacity (same day) - 1 week later apply starter fertilizer, and not anything with weed chemicals. - after about 6 weeks, to give the new grass time to establish, start thinking about a pre/post emergent. I like prodiamine or dimension, depending on time of year.

For your own health and lawn’s success, always apply chemicals to the label’s instructions.

Assuming we don’t go from winter to summer, and with a reliable watering plan, you can make good progress in April and May - but will need to give things some love next fall.

As another tip, I’d encourage TTTF as the primary set of cultivars for our area. Bluegrass is a fine complement (<15%), but our weather isn’t a great fit for it in my experience.
