Germination is usually about 10-20 days depending on temperature and other conditions. Young valerian plants have quite different leave appearance to mature plants, the leaves are not divided, this only occurs as the plants become bigger. It is easy to become confused and unsure of your plants, have faith the leaves will change as they grow and become strongly divided.
Transplant when seedlings are large enough to handle. Grow on in individual pots until plants are about 6 inches, and harden off before planting out. Ensure enough space between plants as they can become quite large.
Harvesting Valerian (Valeriana officinalis).
If intending to harvest the roots grow in a location where it is easy to dig them up again. Wait until at least the second winter before harvesting to allow roots to enlarge. Cut down the flower stalks to allow the plant to concentrate on root growth. Dig roots in early fall to to winter of the second year. Plants can be left for additional years is desired.
