Came home yesterday to find my wife had scarified the lawn.

Is it too late to over seed it? If not should I use a particular type
of seed?

I did some "repairs" to some mole-damaged lawn just over a week ago.
Seeded with Johnson's Quicklawn. It's already germinated. To be safe,
I pop some fleece over the area at night.

Get the right seed and you should be ok.
