Water Borago pygmaea regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogging, especially during cooler months.

In hot, dry weather, increase watering frequency to keep the soil consistently moist but not saturated. Overwatering can lead to root rot.

Pruning is generally minimal for Borago pygmaea. Deadhead spent flowers to encourage further blooming and prevent self-seeding if desired.

Remove any yellowing or damaged foliage as it appears to maintain a tidy appearance and good air circulation. Cut back after flowering if it becomes leggy.

Borago pygmaea is easily propagated from seed, typically sown directly outdoors in early spring or autumn. Seeds germinate readily under favorable conditions.

You can also take cuttings from young shoots in late spring or early summer, rooting them in moist, well-draining potting mix.

Repotting is not a frequent requirement for Borago pygmaea, as it is often treated as an annual or short-lived perennial.

If grown in a container and it outgrows its pot, repot in spring into a slightly larger container with fresh, well-draining potting soil. Ensure the new pot has adequate drainage holes.
