How to grow sage

Salvia officinalis · Lamiaceae · Herb

Sage is a warm-season herb in the Lamiaceae family, usually started indoors and set out as transplants. It wants full sun (six or more hours of direct light) and little supplemental water once established. From sowing to first pick is about 75–90 days. It handles frost well and a light freeze often improves the flavour.

Grower’s note: Hardy perennial to about Zone 4. Gets woody and sparse after 3-4 years - replace it or start cuttings. Lean, well-drained soil; prune lightly in spring but never into leafless wood.

Sowing

Sow about 0.25″ deep, into soil between 55–80°F — germination is quickest near 70°F. It is slow and often erratic to germinate (10–21 days). For an early crop, start seed indoors about 8 weeks before your last spring frost and grow it under bright light.

Spacing & layout

Give each plant about 18″ along the row with roughly 24″ between rows. On a square-foot grid that is 1 per square foot. Allow at least 10″ of loose, workable soil for the roots. It grows well in containers at least 10″ deep.

Fitting it to your season

Sage needs roughly 75–90 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
