I have about 60% crabgrass (patches) where I mow and the rest Bahia. Tried
the crabgrass preemergent for 3 years in Feb/Mar but it still keeps coming
back. I am interested in seeding some Bahia. What can I do and when should I
do it?
Thanks

You're most likely applying the pre-emergent too late.
I'm in the San Joaquin Valley in CA and ours has to be applied in January
since it warms up so early... I would think your area warms up sooner.

Here's some info on crabgrass from UC Davis

I know the summers here are hotter (according to your city website) but you
win with the rain. We only get 5" a year.
You have to maintain your turf at the appropriate height, mowing weekly,
fertilizing correctly, etc. An unhealthy turf is prime for weeds. Easier
to say than to maintain.

Bahia is supposed to be easy to grow from seed. You can order some
