I've have a good sized sage plant in my garden that I planted three years ago. Suddenly half of it has shriveled up.

Any ideas?

For starters, it's not far from the end of its life. Sage is best replaced every 5-7 years or so.

For another, sage has a mind of its own and will often keel over for no apparent reason. One day looks brilliant, the next dead as a dodo.

It's possible that it has recently been overwatered (lots of rain?) and sage really, really can't handle wet feet. I think that is your most likely answer.

Take some cuttings NOW, and start again. Once sage decides to die, you can't stop it.

Yup, you're right. We've had lots of rain recently...five inches one day.
