Light Canna iridifloraSole pieno
The Canna iridiflora should be preferably located in a place where it can have at least a few hours a day of direct solar light. If you desire cleaning the ground from the bulbous plants after flowering, wait for the leaves to dry; later itís possible to take the bulbs out of the ground and place them somewhere dark, cool and dry, until the best season to plant them again.These plants are grown in apartment or in a temperated green house; they can be brought outdoors when the minimum temperatures are above 15į C.

Cultivation Canna iridiflora
The development is erect, they tend to grow both in height and in width, giving origin to a rounded shrub. This plant in the summer assumes a orange colouring; it is large in size and can reach 3 m high. It doesn't keep its leaves in the winter. These plants are bulbeous.

Fertilize Canna iridiflora
Letís use a slow release fertilizer, or manure, when planting, mixing the product to the ground; during the spring letís mix, every 15-20 days, a specific fertilizer for bulbous plants to our irrigation water, starting from the moment in which the first flowers are withering.

Water Canna iridifloraTenere Umido
Water regularly, every 1-2 weeks , wetting the soil deeply with about 1-2 glasses of water ,but waiting for the substratum to dry completely between one watering and another; avoid leaving stagnant water. We suggest not to exceed with the waterings: if the soil remains damp too long, it can favour the development of rotten in the bulbs.

Pests Canna iridiflora
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there arenít flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
