Water Scutellaria adsurgens regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering in winter when the plant is dormant to prevent root rot. Good drainage is crucial.

Prune Scutellaria adsurgens after flowering to maintain a tidy shape and encourage a second bloom. Cut back spent flower stalks to the base of the plant.

In late winter or early spring, you can also trim back any overgrown or dead stems to promote vigorous new growth.

Scutellaria adsurgens can be propagated by division of established clumps in early spring. Carefully separate the root ball into smaller sections, each with roots and shoots, and replant them.

Alternatively, sow seeds in spring under glass or in a cold frame.

Repot Scutellaria adsurgens every two to three years, or when the plant becomes root-bound. The best time for repotting is in early spring before new growth begins.

Use a well-draining potting mix and a slightly larger pot to accommodate root expansion.
