Difficulty: Moderately Easy
Step1
Start hyssop by seed. You can occasionally find the herb in pots at garden centers, but the most common method of acquiring hyssop plants is through sowing seeds. Hyssop should be planted about a quarter of an inch deep and, if grown in a bed, plants should be spaced about a foot apart.
Step2
Pick a sunny location that receives several direct hours of sun per day. Hyssop can grow in partial shade but thrives in full sun as long as you water frequently.
Step3
Plant in large pots, if you choose to grow hyssop in containers. Hyssop has a large root system and must have at least a 10-inch pot, but a 12-inch pot will be more ideal.
Step4
Prune plants as they become long and spindly. Cutting back the foliage will encourage more bushy plants. You'll also need to cut off old flower stalks.
Step5
Grow hyssop as a perennial herb in USDA zones four and above. In zones one through three, hyssop is not hardy and is considered an annual. Hyssop may reseed if grown in a bed, however. Go to the National Arboretum website and choose "USDA Plant Zone Hardiness Map" from the "Research Activities" menu for details on hardiness zones.
Step6
Replace hyssop plants every five years. Even in zones where hyssop is a perennial herb, the plant declines after several years of growing. When the plant begins to decline, replace with freshly sown seeds.
