I need to sow grass on a large area under an oak tree. While I'm at it I
want to over seed my entire front lawn. My question is what seeds, if any,
are best for areas in both shaded areas and areas in full sun?

There are blends that contain sun and shade mixes. However, the area
under a tree is better suited for mulch or shade-loving groundcover.
Grasses really need some sun.

I know autumn is the best time for over seeding, but I don't want to wait
that long. So other than waiting for fall, when would be the second best
time for doing the job?

Spring. The seedlings will have to endure the harsh summer, so
depending on draughts, you may need to plan another overseeding in the
fall.

I live in North Central Texas which is in zone 8.

Thanks
