Rehmannia: Cultivation & Harvesting
considerations for growing and harvesting rehmannia

Rehmannia grows along roadsides on well-draining stony ground. It is also found in woods, on mountain slopes and trail sides. It grows in elevations ranging from near sea level up to 1100 meters (3600 feet).

Rehmannia requires a light freely-draining humus-rich loam, and prefers a neutral to acid sandy soil.

Sow seeds in a greenhouse in the autumn or in the spring. Transplant out the seedlings into individual pots when they are large enough to handle and grow them on for at least their first winter in a greenhouse. Plant them out in late spring or early summer.

Division can be done in spring or root cuttings can be done in winter. Basal cuttings can be taken in the late spring or in the early summer.

When the shoots are about 8-10cm above the ground, harvest the shoots with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.

Harvesting roots of cultivated plants occurs in the autumn or in early winter; whereas harvesting roots of wild plants are done in early spring. Rehmannia root can be used fresh or dried for later use. Some suggest to boil the root 9 times if preparing a cooked version.

Store dried rehmannia root pieces in an airtight container in a cool, dry place.
