Lawn Repair For Your Kings Pride Buffalo Lawn

Just started on this Kings Pride Buffalo lawn here in Woollahra, Sydney.
 
Two main problems here:
1. Onion Weed
2. The owner’s husband tried to kill onion weed with Glyphosate
 
2 weeks ago we fertilised all lawn areas then test sprayed the buffalo as we always do.
 
Today, after seeing the buffalo was okay with the herbicide test spray, we rolled out the Destiny Herbicide spraying (for onion weed control).
 
The damaged areas have been fertilised heavily and will repair themselves over the next 6 weeks.
