Blessing a grave

In Paul Turner's Blog by Paul Turner

Q: At the graveside, one prayer in the Order of Christian Funerals comes with alternatives that depend on whether or not the grave has been blessed. I’ve presumed that if I’m at a Catholic cemetery, I say the version for the grave that has already been blessed, and if I’m somewhere else, I use the other one. Is that right?

A: That’s what I do too.
