Keep the soil consistently moist, especially during the growing season. Water deeply when the top inch of soil begins to dry. Reduce watering in fall and winter, allowing the soil to dry slightly between waterings.

Avoid waterlogged conditions, which can lead to root rot.

Remove spent flower stalks to encourage more blooms and maintain a tidy appearance. Cut back foliage in late autumn or early winter after it has yellowed and died back.

This helps prevent disease and tidies up the plant for overwintering.

Propagate Canna flaccida by dividing its rhizomes in spring. Ensure each division has at least one growth bud. Plant the divisions 5-10 cm deep in well-draining soil. New plants will emerge in warmer weather.

Repot Canna flaccida every 2-3 years, or when the rhizomes have filled the pot. This is best done in spring before new growth begins.

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