How Does Red Sage Propagate? A Quick Guide to the Latest Propagation Methods

Red sage grows in sunny hillside grasslands, beside ditches, roadsides or forest edges, and is distributed across most parts of the country. Propagation methods include seeds, root division, root-crown division or cuttings. Using the root crown as propagation material gives the highest yield, followed by root division.

Seed propagation

For spring sowing, in mid to late March, sow in drills on a prepared raised bed, then cover with plastic film to keep warm and moist, and seedlings will emerge in about 15 days. Thin the seedlings when they are 5-6 cm tall. When the seedlings are about 10 cm tall, lift them from the seedbed and transplant them in place.

Root division propagation

In the south, February to March; in the north, March to April. On a prepared raised bed, dig holes at a row spacing of 33-35 cm and a plant spacing of 23-25 cm, apply base fertilizer at the bottom of the holes, cut the stored seed roots into 5-7 cm segments, with the thick end facing up, and plant 1 segment upright in each hole. After planting, cover with about 3 cm of soil; the soil should not be too thick, otherwise the seedlings will struggle to emerge, and do not plant them upside down, otherwise they will not sprout.

Root-crown propagation

When harvesting red sage roots, select robust plants free of pests and diseases; the thick roots are used for medicine, and the thin roots 0.6 cm in diameter, together with the root crown at the base, are cut off as seed material. Dig holes and plant in the same way as for root division propagation.

Cuttage propagation

Cut robust stems and branches into segments about 20 cm long, insert them as soon as they are cut, to a depth of 1/2 or 1/3 of the cutting, keep the bed surface moist after insertion, and with proper shading they will root in about half a month.
