Growing Tips
- 1Marjoram thrives in full sunlight, so choose a spot in your garden that gets at least 6 hours of direct sun each day.
- 2It prefers well-drained soil, so consider adding sand or gravel to improve drainage if needed.
- 3Water marjoram moderately, allowing the soil to dry out between waterings to prevent root rot.
- 4Space plants about 12 inches apart to ensure good air circulation, which helps prevent fungal diseases.

Saving Seeds
How to Save Seeds
Saving seeds from your Marjoram plant is simple and rewarding, even for new growers! Once your Marjoram flowers have dried on the plant, gently snip off the seed heads and place them in a paper bag. Give the bag a gentle shake to release the tiny seeds, then sift out any plant debris. Let the seeds air dry for a few days, and store them in a labeled envelope or small jar in a cool, dry place—your seeds will be ready for next season’s planting! With just a little care, you’ll have your own homegrown Marjoram seeds and the confidence to keep growing.
