These plants don't agree with cold temperatures during this time of year. They can be grown outside. 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 Dahl's cup lichen should be grown in a bright place, with direct sunlight.
Generalities Dahl's cup lichen
These plants have trunks or roots which store nourishment, originating bulbs or tubers. The Dahl's cup lichen is large in size and 50 cm in height; in the summer it assumes a white colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. These plants give origin to a brush with a rounded form.
Fertilization Dahl's cup lichen
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.
Watering Dahl's cup lichen
Water rarely, about once every 1-2 weeks with 1-2 glasses of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down. 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.
Treatments Dahl's cup lichen
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 Dahl's cup lichen
Locate in a deep and dissolved soil, with an accentuated drainage.
