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 Corydalis diphylla should be grown in a bright place, with direct sunlight.These plants don't agree with cold temperatures during this time of year. They can be grown outside.
Fertilization Corydalis diphylla
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.
Generalities Corydalis diphylla
These plants grow covering the whole land at their disposal. The Corydalis diphylla is a plant for a rock garden. The Corydalis diphylla is small in size and 15 cm in height; in the spring it assumes a purple colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
Watering Corydalis diphylla
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 Corydalis diphylla
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 Corydalis diphylla
Locate in a deep and dissolved soil, with an accentuated drainage.
