Canna indica thrives in consistently moist soil. Water regularly, especially during the growing season, to prevent the soil from drying out.

Aim for saturation but avoid waterlogged conditions, as this can lead to root rot. Reduce watering slightly during dormancy.

Deadhead spent flower stalks to encourage continuous blooming and prevent seed formation. In late autumn, after the foliage has died back, cut the stems down to the ground.

Remove any diseased or damaged leaves as they appear during the growing season.

Canna indica is easily propagated by division of rhizomes. In spring, carefully divide the fleshy rhizomes, ensuring each section has at least one eye or bud.

Replant these divisions in well-draining soil, or start them indoors before transplanting after the last frost.

Rhizomatous plants like Canna indica benefit from repotting every 2-3 years, or when they become pot-bound. Repot in early spring before new growth emerges.

Choose a pot that is slightly larger than the previous one and use fresh, well-draining potting mix.
