Looking for some advice on year two of my Pennington Bermuda Triangle seeded lawn. First year was great, lawn performed well. This spring all the thatch was raked out and watering every two days. The Small portion of the lawn that was sodded is doing great. The seeded portion is coming back real slow, feeling like it is going to have to reestablish from the 10% of plants that are actively growing.

What do you all suggest? Overseeding with more Bermuda? Let it ride out? I am resisting stripping it down and sodding, I feel like there is hope. All advice is welcome, thanks in advance.
