Plant which needs at least a few hours a day of 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.Let's grow the The African-lily In a cold green house or in the house, as they fear frost; we can move them outside in late spring, with minimum temperatures above zero.
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.
The African-lily needs to be watered quite frequently, every 1-2 weeks ; if there are abundant rains we can diminish watering, which should be done only when the soil is dry. The suggested quantity is 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.
