Sage Plant: How to Grow Culinary Sage From Seed or Cuttings

Grow common sage in full sun and very well-drained soil: wet soil is the leading cause of decline and winter loss. Sow seed indoors 6 to 8 weeks prior to your average last frost, or root a summer cutting, and space plants 18 to 30 inches apart. Harvest lightly the first year.

Common sage (Salvia officinalis) is a short-lived, semi-woody perennial shrub from the Mediterranean region, in the mint family (Lamiaceae). This guide draws on thirteen extension services and a university plant library for hardiness, seed, cuttings, spacing, harvest and pruning, and counts the indoor seed-starting window back from the median last frost at four airports.

Common sage and its culinary varieties

The sage you cook with is Salvia officinalis, sold as common, garden or culinary sage. "Sage" names many plants in the Salvia genus, but culinary sage is the only one used widely in cooking. The fresh sage in supermarkets is often Greek sage (Salvia fruticosa), a similar species whose mature leaves come in threes; common sage leaves are always simple.

Pineapple sage (Salvia elegans) is a different plant: it is not winter hardy; it is grown as an annual, mainly as an ornamental, and its flavor is quite different, so it is not generally a stand-in for common sage.

Common sage cultivars differ in leaf color, size and cold tolerance, and the colored forms are less hardy than the species:

Common sage cultivars

Cultivar	Leaves and habit	Cold hardiness, as rated
'Berggarten'	Large, round, silvery gray leaves; mildew resistant; rarely blooms, and its flavor is rated subpar; seems to handle heat better than the species	Zone 5 or 5a
'Purpurascens', also sold as 'Purpurea' (purple sage)	Purple leaves, strongly flavored, 12 to 18 inches tall; used in cooking	Only to zone 6, not dependable in zone 5, and will not reliably survive winter in Iowa; one list rates it not winter hardy
'Tricolor'	Rose-streaked green leaves, white edges	Zone 5b, 6a or 6; one list rates it not winter hardy
'Aurea' (golden sage)	Chartreuse-yellow leaves with dark green near the veins	Zone 5b, 6a or 6; not dependable in zone 5
'Compacta'	Small leaves, compact, 10 inches tall; does not come true from seed	Not given
'Nana'	Compact, 12 to 18 inches tall	Zone 4

Guides split on flavor: one rates the purple and golden types just as good as the gray ones, another says ornamental cultivars may have suboptimal flavor. Our reading: in a cold garden, start with plain common sage, rated to zone 4, or 'Nana' (zone 4); the colored forms are rated only to zone 5 or 6.

Where to plant sage: sun, soil and zones

Give sage the sunniest, driest-draining spot you have. It wants direct sun for 6 hours a day or longer, and good drainage is essential, particularly in winter; partial shade of 2 to 6 hours is also on one light list. In the hottest places, afternoon shade helps.

Drainage matters more than fertility. Common sage will not tolerate wet or poorly drained ground, though it puts up with drought and poor soil; it wants full sun, dry soil and excellent drainage, and very well-drained soil to survive winter. Where your ground stays wet, raised beds, slopes, or sandy or loamy ground are often ideal; our raised bed guide covers building one.

On fertility the guides lean different ways: one wants moderately fertile soil amended with organic matter, while another says the plants ask little in irrigation or fertility. The ideal pH is 6.5 to 7.

How cold can sage take?

Cold is rarely what limits common sage (our reading). It is rated for USDA zones 4 to 8, and one rating runs to 10b. A zone measures winter cold, not a date. The ratings differ at the warm end: two stop at zone 8, in coastal South Carolina sage can be difficult to grow, and it does not do well in hot, humid weather. In Florida, sage can be started from seed or cuttings any time from fall through spring.

Farther north, wet soil is the bigger threat. In Iowa, a protected spot with full sun and excellent drainage can let sage live on as a perennial. For winter, spread 2 to 5 inches of loose mulch (straw, compost, leaves or marsh hay) over the roots once the ground has frozen.

How to grow sage from seed

Sow sage indoors 6 to 8 weeks prior to your average last frost date, or outdoors around that date: as much as two weeks ahead of it by one count, after all danger of frost by another. Either way the plants may not flower in their first year.

Indoors, start herb seed under fluorescent lights in late winter, the lights 4 to 6 inches above the seedlings and on 14 to 16 hours daily, or grow the seedlings in a sunny window at a cool 60 F. As a general rule, sow seed twice its diameter deep.

Set the seedlings out after frost danger has passed, once the soil stays at 50 F or warmer; sage is one of the cool-season herbs that tolerate cooler soil. For seed sown outdoors, aim for soil of 60 to 70 F.

When to start sage seed indoors in four cities

Station (1991-2020 normals)	Median last spring 32 F	Indoor seed start, 6 to 8 weeks earlier	Median first fall 32 F
Minneapolis-St. Paul, MN	Apr 23	Feb 26 to Mar 12	Oct 18
Chicago O'Hare, IL	Apr 16	Feb 19 to Mar 5	Oct 28
Washington Reagan, VA	Mar 24	Jan 27 to Feb 10	Nov 18
Atlanta Hartsfield, GA	Mar 15	Jan 18 to Feb 1	Nov 20

The indoor window is our arithmetic: 6 to 8 weeks counted back 42 to 56 days from each median. These are medians (the 50 percent column), so in roughly one spring out of two, frost returns after the spring date shown. That date is not for setting out transplants: wait until frost danger is past. In the fall column, roughly one year in two brings its first 32 F night before the date shown.

Patience is the catch. One guide finds sage easy to start from seed; others prefer cuttings or transplants, because seed may take several years to give a plant worth harvesting and growing from seed is slow. For an old packet, our seed longevity guide covers testing it before you sow.

How to grow sage from cuttings

Sage roots readily from cuttings, and a cutting usually keeps its parent's traits: cutting-grown plants generally establish faster and keep the parent's characteristics, which is why many gardeners propagate favorite cultivars this way. Softwood stem cuttings taken in summer root in moist, well-drained potting mix, and rooting hormone is generally unnecessary. The steps:

1. Take a tip cutting from healthy, soft growth. Cut 2 to 5 inches of healthy tip growth just below a node with a sharp, clean knife, any time in late spring or summer.
2. Strip the lower leaves. Pull off the leaves on the lower half.
3. Skip the hormone, or use it. Rooting hormone is generally not necessary for sage; dip the end if you have hormone on hand.
4. Set it in a moist medium. Use moist, well-drained potting mix, or moist perlite; several cuttings fit in a 6 inch pot.
5. Tent and shade it. Cover the pot with a clear plastic bag and keep it in indirect light, checking that the perlite stays moist.
6. Pot it up once rooted. Move each cutting to its own pot once roots reach 1 inch or more; rooted herb cuttings can winter in a sunny window or a cold frame and go out the next spring.

Rooting times given are for herbs in general, not sage alone: most should root in two to six weeks.

Two routes need no pot. Layering roots a stem still attached to the plant and is a reliable way to increase perennial herbs such as sage: layer any time from spring to fall and cut the rooted shoot free the next spring. Division suits a big clump: divide it in spring or fall.

A cutting also carries sage through winter: root late-summer cuttings, keep them potted in a sunny spot indoors and replant them after the danger of frost.

How far apart to plant sage, and how to care for it

Space sage plants 18 to 30 inches apart and give them room to spread; 2 feet sits inside or at the edge of every spacing given (our reading). Room for air helps: good air circulation lowers the risk of foliar diseases, powdery mildew may develop where air circulation is poor, and most of sage's problems trace to wet soil, poor drainage or overcrowding.

Watering and feeding

Water new plants until they establish, then let sage dry between drinks: water afterward only in long dry spells, or wait until the soil is dry, then soak it. Sage generally does better kept slightly dry, though one guide adds a counterweight: it tolerates drought but produces better with consistent water.

Feed lightly or not at all. A thin layer of compost is enough, since rich soil lowers the essential oils that carry flavor; one guide that also covers commercial fields feeds again 6 to 8 weeks after planting.

Pests and diseases

Possible pests are leafhoppers, slugs, spider mites and spittlebugs, and diseases include root rot, verticillium wilt and powdery mildew; good drainage and moving air lower the risk. Mint rust, orange or brown pustules under the leaves, can spread to sage from nearby mint plants, or from sage to mint.

Growing sage in pots and indoors

Sage can winter indoors in a pot. The smaller varieties suit containers, and variegated, purple and golden sage are among the herbs recommended for them. Indoors, light is often the limit: give it a south or west window with four to six hours or more of direct sun, plus 14 to 16 hours of grow light daily in winter. Sage is one of the herbs that should dry between waterings, and clay or terracotta pots help the mix dry. Left outdoors, a potted sage will not overwinter without extra protection.

How to harvest sage leaves

Pick single leaves or snip stem tips as needed, leaving most of the plant standing so it keeps growing. Harvest the leaves in spring and summer, lightly in the first year so the plant can establish before heavier cutting, and pick from new growth in spring and early summer.

• First harvest. Count about 75 days between planting and the first harvest.
• Bigger cuts. Cut 6 to 8 inches off the top of the plants at least twice a season, or cut 6 to 8 inch stems just before the plants bloom.
• How much at once. Stop short of half the plant; cutting back more will stop it producing. For perennial herbs in general, one guide takes no more than a third of the plant at once.
• Time of day. Pick in the morning, once the dew has dried, for the highest concentration of oils.
• Late season. Stop heavy harvests by late summer or early fall so the plant can harden off for winter; one northern guide does not cut back after August.

Regular picking encourages branching. For drying, harvest before flowering.

The flowers are edible too, with an herbal, musky flavor, but they are not to be eaten in large amounts.

Storing fresh and dried sage

Fresh sage can keep for several days in the refrigerator. To keep it longer, dry small bundles somewhere warm, dark and well ventilated and store the brittle leaves airtight, away from heat and light; sturdy herbs such as sage can be dried without a dehydrator. Packed loosely in a freezer bag, frozen sage is good for a year.

Pruning woody sage in spring

Prune sage in spring, just as new growth starts, and cut back to stems that still carry leaves or buds. Remove winter-damaged stems and avoid cutting deep into old wood that lacks healthy buds: mature woody stems seldom sprout new growth, and one guide prunes only the previous year's growth on sage.

How hard to cut is where guides differ: one hard-prunes once regrowth shows, removing dead, woody stems but not new growth, while another prunes lightly. Pruning during the season also keeps the plant from getting leggy and controls flowering, and some guides allow a cut after flowering.

Older plants often turn woody and less productive, so they usually need replacing every 3 to 5 years, though a sage plant can live 15 to 20 years.

Dividing plants every few years rejuvenates them, and a rooted cutting or layer from your own plant makes a ready replacement.

Sage seeds and supplies

What you need: common sage seed or a rooted cutting; for seed, clean containers such as a cell tray, seed-starting mix and a light for the indoor weeks; a clay or terracotta pot with drainage holes if it will winter indoors; and a clean, sharp knife for cuttings. For a colored cultivar, buy a plant or root a cutting, since most named varieties are propagated vegetatively.

Frequently asked questions

Is sage a perennial?

Yes. Common sage is a short-lived, semi-woody perennial, rated for USDA zones 4 to 8, and one rating runs to 10b. Plants are often replaced every few years, usually every 3 to 5, and wet soil is the leading cause of winter loss.

How do you harvest sage?

Take single leaves or stem tips as needed and leave most of the plant to keep growing. Harvest lightly in the first year. After that, cut 6 to 8 inches off the top at least twice a season, but never more than half the plant, and harvest before flowering. Stop heavy harvests by late summer or early fall.

Can you grow sage from cuttings?

Yes. Softwood stem cuttings taken in summer root in moist, well-drained potting mix, and rooting hormone is generally not necessary. Cutting-grown plants generally establish faster and keep the parent's traits, and 'Tricolor' is among the cultivars propagated vegetatively.

When should you plant sage?

Sow seed indoors 6 to 8 weeks prior to your average last frost date, or outdoors around that date. Set transplants out once frost danger is past and the soil is consistently 50 F or warmer; sage is one of the cool-season herbs that tolerate cooler soil.

How far apart should you plant sage?

Space sage plants 18 to 30 inches apart; 2 feet fits every spacing given. Air matters too: good air circulation lowers the risk of foliar diseases, and powdery mildew may develop where it is poor.

Can you grow sage in a pot indoors?

Yes. Some herbs, sage among them, may be grown in pots and brought inside for winter; set it in a south- or west-facing window. Ideally give it four to six hours or more of direct sun, water once the mix is dry to the touch, and add 14 to 16 hours of grow light a day in winter.

Should you let sage flower?

If you grow it for leaves, cut before it does: harvest before the plant flowers (for drying especially), and prune during the season partly to control flowering. Bees and butterflies visit the flowers, which are edible, with an herbal, musky flavor, though not to be eaten in large amounts.

Why is my sage plant dying?

Wet soil is the usual cause. Root rot is the most common problem and can quickly kill sage in wet ground, and sage will not tolerate wet or poorly drained soil. Our suggestion: move it to a raised bed or a fast-draining pot, and water only once the soil is dry.
