Fill a seed-starting container 2/3 full with sterile seed-starting medium. Sow the seeds in the medium and cover with damp paper towels. Keep the towels damp at all times. Keep the room temperature at 70 degrees or above.
Fill a planter 2/3 full with rich humus soil. Transplant the seedlings into the planter when two sets of leaves measuring 3 to 4 inches have germinated.
Place the planter in full sun. Damiana requires eight to 10 hours of sunlight a day to thrive. Keep the soil moist but do not overwater. Only hydrate the plant when the soil feels dry.
Add a light liquid fertilizer to the herb during the spring and summer months. Follow the mixing and feeding instructions for your specific brand of fertilizer.
Prune the shrub with a pair of sterilized pruning shears to control the size and bushiness of the plant.
Find a location in full sun with well-drained soil to plant the Damiana. Dig a small hole with a garden shovel. This hole is where you will plant the herb.
Sow Damiana herb seeds in spring after the last frost or in early fall. Alternatively, transplant Damiana plants first started indoors.
Measure 24 to 36 inches from the hole. Place the seed or seedling in the hole and cover it gently with the surrounding soil. Keep any greenery on the seed or seedling above ground.
Continue planting the Damiana seeds or seedlings with a spacing of 24 to 36 inches between each plant.
Water the plant regularly and fertilize in spring and summer with a light liquid fertilizer. Follow the mixing and feeding instructions for your specific brand of fertilizer.
