The waterings

Canna indica plants are very demanding in terms of water and humidity: throughout the flowering period they need constant watering, the ideal would be every 2 or 3 days, avoiding that the cultivation soil does not dry out completely between a watering and the other. By doing this, not only will you ensure abundant and prolonged flowering, but also a healthy and luxuriant leaf system. With the arrival of the first colds, however, the watering must be completely suspended in order to allow the plants to enter vegetative rest. In this period, in fact, they particularly fear water and humidity and, when extracting the rhizomes from the ground to make them winter from frost, it is necessary to pay close attention so that they are not wet or damp.


How to cultivate

The Canna indica rhizomes should be buried in the spring in a soft soil with good drainage. When planting them, keep in mind that the plants will become very large, so place them well apart from each other. To increase the development of the buds, as soon as the flowers wither, proceed with their removal otherwise the plants will spend too much energy in the production of fruits and seeds from the pollinated flowers. In winter the Canna fiorifera plants grown in pots and the unearthed rhizomes of the plants grown in the garden must be placed in cold rooms with temperatures around 10 ° C, because they need this temperature range to start their vegetative rest. In the spring, avoid the frosts, you can place them outside again.
