(If lawn/sod qquestions aren't allowed in here, apologies! I'm coming from Fine Homebuilding's forums and thought this might be a good place to ask...)
We got new sod about 2 months ago. They put down some new topsoil, graded (sort of), and then I began watering. I watered every day for about 3 weeks and have since been doing about 40 minutes every other day.
We just got back from vacation (left sprinklers on timers) and now I have two rather large areas that are completely brown. It's been hot and dry, so at first I thought it just might have gone dormant, but considering I've watered pretty much the entire yard evennly, I assume I just now have dead spots.
Any reason to wait until spring to see if it returns or is it safe to assume it's just dead and time to open the checkbook and buy some new sod (and this time, lay it myself)?
