I want to over-seed my lawn in the near future. I would like to know
which grass seeds should I use.

Currently, the bluegrass in my lawn is doing OK, and I probably don't
want to replace it. But it is kind of thinning out in some areas. I
believe this has something to do with the fact that I don't water
enough and bluegrass needs a lot of water. Unfortunately, we have
occasional water shortage problem in where I live (Northern New
Jersey). According to locals, we have watering-ban every three to four
years. Seem like I should choose a grass seeds that is drought
tolerate.

But I am under the impression that bluegrass doesn't work well with
other grasses such as fescus because bluegrass will crowd out other
grasses when the condition is good for bluegrass. I may have to stick
with bluegrass or something that can grow with bluegrass.

My questions a

- Is there any drought-tolerate bluegrass, or bluegrass that is
"sort-of" drought-tolerate to some degree?

- Any other better choice? (No, I am not going to replace the
entire lawn at this point)

Thanks in advance for any suggestion.
