If necessary we can extract the bulbs from the ground, during the vegetative rest; after letting them dry we should place them in a cool, dry and dark place. During the most indicated season we can plant them again. These plants don't like cold weather, therefore in the Spring it is best to set them outside only when the temperatures are above 15°C.the Canna generalis should be grown in a bright place, with direct sunlight.
Watering Canna generalis
These plants don't need too much water; staying in a soil which is too damp, can easily cause the development of rotten in the bulbs. During this period of the year the the Canna generalis needs regular watering, which should be done letting the soil dry between one watering and the other; let’s irrigate every 1-2 weeks with about 1-2 glasses of water .
Fertilization Canna generalis
Bulbous plants use nutritious substances stored from the previous year for their flowering ; this is why usually the soil should be enriched, during planting, with a slow release or organic fertilizer. Later we must fertilize with a specific fertilizer for bulbous plants, every 15-20 days, starting from the moment in which the first flowers are withering.

Treatments Canna generalis
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
Soil Canna generalis
We suggest an averagely drained substratum, which slightly withholds humidity.
