Aquilegia eximia prefers consistently moist soil, especially during its active growth and flowering period. Water deeply when the top few centimeters of soil feel dry.

Reduce watering during the dormant season, allowing the soil to dry out slightly between waterings to prevent root rot.

Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding if not desired.

After flowering, you can cut back the foliage to tidy the plant and encourage a second flush of growth, or leave it for winter interest. Remove any dead or damaged stems promptly.

Aquilegia eximia is best propagated from fresh seed sown in late autumn or early spring. Seedlings can be transplanted when large enough to handle.

Division of established clumps is possible in early spring, but this species often prefers to be left undisturbed and may not respond as well to division.

Repotting is generally not necessary for Aquilegia eximia, as it prefers to establish in its permanent location.

If container-grown plants become root-bound, repot in early spring into a slightly larger container using well-draining potting mix. Ensure the new pot has adequate drainage holes.
