Hyssopus officinalis prefers well-drained soil and is drought-tolerant once established. Water moderately during dry periods, allowing the soil to dry out slightly between waterings.

Avoid overwatering, as this can lead to root rot. Reduce watering in cooler months.

Prune Hyssop in early spring to remove dead or damaged stems and to shape the plant. Lightly shear back after flowering to encourage bushier growth and prevent it from becoming leggy.

Regular pruning maintains a tidy appearance and promotes better air circulation.

Hyssop can be propagated by seeds sown in spring or by stem cuttings taken in late spring or early summer. Seeds can be sown directly outdoors after the last frost or started indoors a few weeks prior.

Cuttings root readily in well-draining soil.

Hyssop generally does not require frequent repotting and prefers to be slightly pot-bound. If growth slows or the plant becomes root-bound, repot in spring to a slightly larger container.

Ensure the new pot has adequate drainage holes.
