Frequently Asked Questions

Why is my sage woody and scraggly?

Sage becomes woody with age. Prune heavily in spring (before new growth) to rejuvenate. Replace plants every 4-5 years when they become too woody.

Can I harvest sage year-round?

Yes in mild climates. In cold zones, harvest heavily before frost and bring some indoors. Fresh sage has the best flavor, but dried sage is traditional for stuffings.
