Anise Hyssop prefers consistently moist, well-drained soil, especially during its establishment phase and dry spells. Water deeply when the top inch or two of soil feels dry to the touch, ensuring good drainage to prevent root rot. While it appreciates regular moisture, established plants exhibit good drought tolerance, making them relatively low-maintenance. Avoid overwatering, as soggy conditions can be detrimental. Reduce watering frequency in cooler, dormant periods.

Pruning Anise Hyssop is beneficial for maintaining plant health and encouraging continuous blooming. In early spring, cut back old, woody stems to about 6 inches from the ground to promote fresh, vigorous growth. Throughout the summer, deadhead spent flower spikes to encourage new blooms and prevent prolific self-seeding, if desired. This also helps keep the plant tidy and extends its ornamental appeal.

Easily propagated by seed, which can be direct-sown in spring or fall. It also readily self-seeds. Division of mature clumps in spring or fall is another effective method. Stem cuttings can be taken in late spring or early summer for rooting.

Anise Hyssop is typically grown outdoors in gardens, but if grown in a pot, repotting may be needed every 1-2 years. Choose a pot one size larger with good drainage. Repot in early spring before new growth begins, refreshing the soil and checking roots.
