When to plant/propagate
Marjoram is freeze-sensitive, so in cold winter microclimates grow as an annual or in a container.
- From seed: Direct seed after the last frost date in spring, or sow seeds indoors 8-10 weeks prior to the last frost date
- Transplants: Plant seedlings when danger of frost is past
- Cuttings & divisions: Propagate from cuttings prior to bloom. Divisions can be done year round
- For best leaf flavor, do not allow plant to flower
- Harvest both the tender leaves (to be added at the end of cooking) and hardier leaves with whole stems (typically added at the beginning of the cooking process, then removed)
- For the most tender leaves, harvest frequently to encourage new growth and prevent flowers from developing. Pinch off any flowers that do develop
- Dry the leaves for winter use. Shelf life is approximately one year
- Many beneficial insects appreciate marjoram flowers, so consider allowing some plants to flower
Indoors: Marjoram can be grown as an indoor plant with 5-6 hours of bright light from a sunny window, or 12-16 hours of supplemental light provided by cool white fluorescent or LED lamps
Common pests & diseases: Leafhoppers
