Sage is a shrubby sprawling gray-green perennial herb.  When growing sage in your herb garden, plant it near the back or as a border, as it can grow up to approximately 2 feet tall. Its leaves are used as an herb for it’s culinary flavoring, aromatic scent, and health-giving properties.  Growing sage will provide not only a pretty plant that lends color and texture to your herb garden, but that is also useful in attracting important pollinators (primarily bees) to your garden.  (Honey from sage flowers is a wonderful treat!)  In the kitchen, the sage herb is used primarily to enhance the flavor of meats and cheeses.  It is a very strong flavor that can be overpowering, if used in excess. 

If you have a large pot, sage is a good choice for container gardening also (for more information: container gardening).

Gardening Advice Tip: Sage is a good companion plant for rosemary, carrots and cabbage. (for more information: companion planting.)

In the 17th Century, it was believed that the condition of a home’s sage bush reflected the financial state of the home.  If the sage bush was flourishing, it was thought that the home’s finances were also.  In the days of the Roman Empire, women used a strong infusion (tea) of the herb to darken their hair.

Sage tea is considered by many Asian traditions to be strengthening to the digestive system and calming.

Fresh leaves rubbed on your teeth and gums are reported to work as a breath freshener, and to strengthen your gums.  A sage compress can help ward off infections and speed the healing of wounds.

Sage is reputed to stimulate the muscles of the uterus, so it should be avoided during pregnancy.

Climate & Growing Conditions (back to top)

Sage will grow in most climates, but if you experience severely cold winters, you may want to consider keeping this plant as a member of your container garden and bringing it indoors for the winter.  At the very least, apply a heavy layer of mulch in the late fall to protect if from winter’s cold.

If you’re in a very wet gardening climate, consider a raised bed garden or else container gardening this plant.  It’s not particularly happy in soggy situations.

Sage prefers a full-sun location. 

How to Prepare the Herb Garden Soil (back to top)

Sage seems to grow the best in light well-drained gardening soils.  They will grow in average soils, and tolerate dry conditions. For optimal growing conditions, prepare the garden plot soil to a pH of 5.5 to 6.5. (Information on how to test your garden soil pH level)

Gardening Advice Tip: If the soil is heavy, you may experience root-rot. Try mixing in compost to help the soil drain better.

How to Plant & Grow Sage (back to top)

Sage plants will grow for several years. When you see that they're starting to wane (after 4 years or so), start fresh plants from cuttings, or from seeds. 

Growing sage from seed:  sow seed in the herb garden in the late spring.  Cover lightly with soil and keep the soil moist (not soggy) until it germinates.  Thin plants to 18” apart.

Growing sage from cuttings:  in late spring/early summer, trim shoots from plants (at least 6” long). Snip the bottom leaves from the stem (don’t pull them off, or you’ll damage the stem). Some gardeners find that placing the cuttings in a glass of water will cause the plant to grow roots. However, for your best chance at success, dip the bottom ½” of the stems in a root-inducing hormone powder (available online, at garden centers, and even Wal-Mart). Shake off the excess powder, and plant in a light planting mixture of perlite and peat moss (essentially, a seed-starting type mixture). The soil mixture should be lightly damp, but not wet. Using a spray bottle to water works best.  To speed up the process, place a heat source below the rooting bed. Once the cuttings have established roots, you can then transplant them into containers. By the following spring, the plants will be established enough that you can move them out of doors, if desired.

Gardening Advice Tip: When the young plants are growing freely, pinch/trim off the branch ends/tops to make them branch out and fill-in. For more established plants, prune them in the spring.

You can grow sage by dividing, but it’s not the preferred method.

How to Water (back to top)

Water plants only during dry periods, up to once or twice per week.

How to Fertilize Sage (back to top)

For optimal growing conditions, add a general purpose fertilizer once or twice a season and water it into the soil.

How to Harvest Sage (back to top)

Harvest young, tender leaves for the best flavor, before the plant flowers.  Pick a nice dry morning for harvesting (after the dew is gone), and pick before you get to the hottest part of day. 

Gardening Advice Tip: Stop harvesting in early fall, to allow the plant to prepare for winter.

Storage:

How to Dehydrate / Dry Sage (back to top)

Dry leaves in a dry shaded area until brittle.  Store in an airtight container in a dark location (like a cabinet) to prevent discoloration.

You can also dehydrate sage using a dehydrator on a low temperature.  Keep the temperature at or below 100 degree (F) or you’ll risk damaging the herb’s natural oils.  Store in an airtight container in a dark location (like a cabinet) to prevent discoloration.

How to Freeze Sage (back to top)

Sage keeps its flavor best when frozen, but isn’t as visually pleasing.  Wash sprigs of sage and pat them dry.  Place them on cookie sheets and place in the freezer.  Once frozen, remove from freezer and strip the leaves.  Place the leaves in an airtight container and store in the freezer.  Frozen sage stores well for up to 1 year.
