Timing and Technique for Harvesting Mullein Leaves
Mullein is a medicinal plant that has been used for centuries to treat various conditions due to its anti-inflammatory, antimicrobial, and analgesic properties. However, harvesting the leaves at the right time and in the proper manner is important to obtain the full benefits of mullein.
Mullein Plant Overview
Mullein is a biennial plant that grows a large rosette of leaves in the first year and a tall flowering stalk that can reach up to 8 feet in its second year of growth. The leaves and flowers contain the medicinal compounds that are used to make herbal preparations.
When Does Mullein Bloom?
Mullein plants produce yellow flowers on their tall stalks starting in late spring and continuing through the summer months. The seeds ripen in late summer and fall. Once the plant goes to seed after flowering, the leaves become less potent for medicinal uses.
Best Time to Harvest Mullein
For optimal medicinal potency, the leaves should be harvested just before the plant flowers. This is usually in early spring of the plant's second year of growth.
Harvest the leaves on a dry, sunny day in the morning after any dew has dried. Sunlight helps drive the production of medicinal compounds in the leaves.
Signs Leaves Are Ready for Harvest
Mature mullein leaves that are ready for harvesting will typically have these features:
- Leaves are very large, up to 12 inches long
- Leaves grow closely spaced together on short stems
- Leaves feel thick and soft to the touch
- Leaves are bright green and may have fuzzy hairs
How to Harvest Mullein Leaves
Harvest Individual Leaves Gently
Only harvest a few leaves per plant to avoid excessive damage. Gently pinch or cut the leaves near the base, leaving some stem attached. Handle softly to avoid bruising.
Use Clean Gardening Shears or Scissors
Sterilized, sharp gardening shears or scissors will create clean cuts and minimize injury to the mullein plants. Wipe blades with rubbing alcohol between plants.
