Sage

Salvia officinalis · Herb

A shrubby herb with soft, gray-green leaves and a warm, earthy flavor. Like other dry-climate herbs it wants sun, sharp drainage and restraint with the watering can. A plant stays productive for several years before getting woody.

When?

Plant out in spring after the last frost. Seeds can be started indoors 6–8 weeks earlier, though cuttings or young plants give a faster start (estimated).

Step by step

  1. Sow seeds 1/8 in deep or root 3–4 in cuttings in a gritty mix.
  2. Plant in full sun in light soil; add grit to heavy clay.
  3. Water young plants regularly, then only when the soil dries.
  4. Feed very lightly, if at all; lean soil gives stronger flavor.
  5. Harvest leaves as needed, taking no more than a third at once.
  6. Cut back by about a third in spring to keep plants compact.
  7. Replace plants once they become very woody and sparse.

Common problems

Wilting with wet soilRoot rot; improve drainage and water less.
White powdery leavesPowdery mildew; give more space and sun.
