Problem Salvia

[Garvey]

I have recently grown some splendid Salvia plants, strong and healthy, something to be proud of! I then carefully hardened them off and finally planted them in my flower beds. After two days in the beds the leaves turned brown and started to curl. Selective plants shrivelled and disappeared!. Can anyone help?

Only certain plants?
Have ants or slugs chewed through the roots?

I don't think so I used slug pellets and ant powder when I planted?
