Cannas thrive in consistently moist soil, especially during their active growing season. Water regularly, allowing the top few centimeters of soil to dry slightly between waterings.

Reduce watering in autumn as the plant prepares for dormancy. Avoid waterlogged conditions, which can lead to root rot.

Deadhead spent flowers regularly to encourage continuous blooming and prevent seed formation. In autumn, after the first frost has blackened the foliage, cut the stalks back to ground level.

This removes dead material and prepares the rhizomes for overwintering.

Cannas are easily propagated by dividing their rhizomes in spring before new growth emerges. Each division should have at least one growth bud.

Alternatively, they can be grown from seed, though this may result in variations from the parent plant and requires stratification.

Cannas are heavy feeders and benefit from repotting every 1-2 years, ideally in early spring before active growth begins. Choose a pot that is slightly larger than the previous one, ensuring good drainage.

Use a rich, well-draining potting mix.
