It should be fine once you cease irrigating but...if you're watering enough to get pond smelling grass, you're probably watering too much.

Check the soil. If it's sodden, back off on the watering. Unless you have seed down (and it's really too early for that!), most things like sod or patching do better when they're only moist.

Heck, even seed does better at moist to damp to merely slightly wet. When sodden, it tends to rot.

Agree. Seedlings need only enough moisture to keep the seed moist, not so much that you saturate the soil 6 inches deep.

My wife recently patched some sod into new areas of our yard, and I'm watering those once per day for 3 minutes.
