Repair lawn scorched by fire

Distorted Vision

I had a load of timber to dispose of and the local dump is closed because of Covid-19. I used by Weber Fireplace to burn it all. I put a large patio slab underneath but the fire spread and burnt the area around it.

How do I best repair? My course of action was to rake out the area and apply Miracle Gro Patch Magic. 

Any other suggestions?

Got to be worth a try ! Nearly a month on, how's it looking?
