Water Thymus zygis sparingly once the soil has dried out. It prefers well-draining conditions and can be susceptible to root rot if overwatered.

Allow the soil to become quite dry between waterings, especially during its dormant periods in winter.

Prune Thymus zygis lightly after flowering to maintain a compact shape and encourage bushier growth. Remove any dead or straggly stems.

Hard pruning in late autumn or early spring can rejuvenate the plant, but avoid cutting back into old wood as it may not regrow.

Propagate Thymus zygis from semi-hardwood cuttings taken in summer or from seed sown in spring. Cuttings should be rooted in a well-draining medium.

Seeds can be sown in a cool greenhouse or outdoors after the risk of frost has passed.

Repot Thymus zygis every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, such as a succulent or cactus blend. Ensure the new pot has adequate drainage holes.

Repotting is best done in spring before new growth begins.
