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. Plant which needs at least a few hours a day of sunlight.We suggest growing the the Imperial fritillary outdoors year round, as they don't fear cold weather.
Feed Imperial fritillary
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.
Care Imperial fritillary
These plants give origin to a brush with a rounded form. These plants have trunks or roots which store nourishment, originating bulbs or tubers. The Imperial fritillary is large in size and 1,5 m in height; in the spring it assumes a orangered colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
Irrigation Imperial fritillary
Watering takes place only when the soil has been dry for days, usually every 1-2 weeks can be enough; if the climate is particularly hot we can slightly intensify the irrigations, using 1-2 glasses of water . 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.
Adversity Imperial fritillary
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.
Substrate Imperial fritillary
Locate in a deep and dissolved soil, with an accentuated drainage.
