The African-lily should be grown in a bright place, with direct sunlight. 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.The African-lily can't stand temperatures below zero; they should be grown in cold green houses or at least in a place where they are sheltered by the wind; when every risk of late freezings has gone by we can place them outside or remove the protections.
These plants give origin to a brush with a rounded form. The African-lily is medium in size and 1 m in height; in the summer it assumes a blue colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. The African-lily is a perennial herb plant.
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.
During this period of the year the The African-lily needs regular watering, which should be done letting the soil dry between one watering and the other; letís irrigate every 1-2 weeks with about 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.
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.
We suggest an averagely drained substratum, which slightly withholds humidity.
When wanted we can grow these plants in a vase. The indications given in this article are related to a medium size plant.
