We suggest growing the The Allium caeruleum in the garden; these are very rustic plants. 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.We suggest to position the The Allium caeruleum in a sunny spot at least a few hours a day.
Cultivation Allium caeruleum
These plants have trunks or roots which store nourishment, originating bulbs or tubers. The Allium caeruleum is medium in size and 80 cm 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. These plants grow covering the whole land at their disposal.
Fertilize Allium caeruleum
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.
Water Allium caeruleum
Water sporadically, with 1-2 glasses of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 1-2 weeks . 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.
Pests Allium caeruleum
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.
Mold Allium caeruleum
Locate in a deep and dissolved soil, with an accentuated drainage.
Plant Allium caeruleum
When wanted we can grow these plants in a vase. The indications given in this article are related to a medium size plant.
