Parietaria hespera prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during dormancy in cooler months, but do not allow the soil to dry out completely. Ensure good drainage to prevent root rot.

Prune to maintain desired shape and size, and to encourage bushier growth. Remove any leggy or dead stems at any time. Pinching back the tips of young plants will promote a more compact form.

Heavy pruning can be done in early spring before new growth begins.

Easily propagated from stem cuttings. Take 4-6 cm cuttings in spring or summer and root them in moist potting mix or water. Cuttings typically root within a few weeks.

Seeds can also be sown in spring, but cuttings are generally more reliable and faster.

Repot young plants annually or every two years in spring to provide fresh soil and more space. Mature plants can be repotted less frequently, only when root-bound. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid over-potting.
