Borage prefers consistently moist soil but dislikes waterlogging. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering during cooler months when growth slows. Ensure good drainage to prevent root rot.

Overwatering can lead to fungal diseases.

Pinch back young plants to encourage bushier growth. Deadhead spent flowers to promote continuous blooming and prevent self-seeding if not desired.

Prune away any diseased or damaged foliage promptly to maintain plant health and vigor.

Borage is easily grown from seed. Sow seeds directly in the garden after the last frost or start indoors 4-6 weeks prior. Seeds germinate readily and young plants transplant well. It also readily self-seeds.

As borage is typically grown as an annual or biennial and prefers direct sowing, repotting is rarely necessary. If grown in a container and it becomes root-bound, a slightly larger pot with fresh potting mix can be used in spring.
