The damage to the lawn is like any other damage to the property done by the tenants. You can use their security deposit to pay for the repair. If you have a lease that requires the tenants to maintain the property you can serve them with a demand to fix the lawn and if they don't then you can serve them with a notice of lease violation and thereafter follow the terms of the lease to, maybe, terminate their tenancy.
