Keep soil consistently moist but not waterlogged, especially during warmer months. Water thoroughly when the top centimeter of soil feels dry.

Reduce watering frequency in winter, allowing the soil to dry out slightly between waterings to prevent root rot. Ensure good drainage to avoid standing water.

Deadheading spent flowers encourages more blooms and maintains a tidy appearance.

Trim back the plant lightly after the main flowering period in late summer or early autumn to encourage dense, compact growth and prevent legginess. Remove any dead or damaged foliage as needed.

Azure bluets can be propagated by division in early spring or autumn. Carefully dig up clumps and separate them into smaller sections, ensuring each section has roots and shoots.

Alternatively, collect seeds in late summer or autumn and sow them in a cold frame or directly in the garden. They may also self-seed readily.

Established plants generally do not require frequent repotting and prefer to be slightly root-bound. If repotting is necessary, typically every 2-3 years, do so in early spring or autumn.

Choose a pot only slightly larger than the current one with ample drainage holes. Use a well-draining potting mix.
