We got our back lawn resodded last summer, and it seemed to take well
(i.e: Most of it knitted together and it grew to the point that it
needed to be mowed regularly). When the snow melted off of it this
spring, however, it came back VERY spotty; Most of it appears to be
dead, with just a few sporadic green patches. We've had a fairly wet
spring, plus we have watered it ourselves, too. Our back yard is
fairly shady, but the grass didn't seem to mind that last summer. Any
ideas what went wrong, and/or what we could do? Thanks!
