Light Requirements
Draba asprella Greene var. typica C.L. Hitchc. prefers full sun to partial shade. It can thrive in relatively shaded conditions but may not flower as much. In contrast, it may suffer from sunburn and stunted growth if exposed to intense sunlight for too long.
Temperature Requirements
This plant species can tolerate a wide range of temperatures. The optimal temperature range for growth is from 50° F to 65° F (10°C to 18°C). However, it can survive in temperatures as low as -20°F (-29°C) and as high as 80°F (27°C).
Soil Requirements
Draba asprella Greene var. typica C.L. Hitchc. prefers well-drained soils that are rich in organic matter. The soil should have a pH between 6.0 to 7.5. This plant species is adaptable to different types of soil, including sandy and clayey soils. It can also survive in nutrient-poor soils but may require extra fertilization to promote optimal growth.
Cultivation Methods
The Draba asprella Greene var. typica C.L. Hitchc. plant prefers to grow in well-drained soils that are slightly acidic to neutral in pH. They thrive well in full sunlight and require at least six hours of direct sunlight a day. It is essential to ensure that the plant has access to adequate air circulation to prevent fungal infections.
Watering Needs
The Draba asprella Greene var. typica C.L. Hitchc. plant requires regular watering to establish a deep and healthy root system. Watering should be done infrequently but deeply to avoid waterlogging the plant. It is best to water the plant in the early morning hours, allowing the excess water to evaporate throughout the day.
Fertilization
The Draba asprella Greene var. typica C.L. Hitchc. plant requires fertilization with a balanced fertilizer during the active growing season to thrive successfully. Fertilization should be done at least once every two weeks, following the recommended dosage as stated in the fertilizer's instructions. Over-fertilizing the plant can cause a buildup of salts in the soil, ultimately leading to root burn and stunting plant growth.
Pruning
The Draba asprella Greene var. typica C.L. Hitchc. plant requires occasional pruning to promote bushier growth and encourage flower production. Pruning should be done, preferably in late fall or early spring, ensuring that the plant is dormant. It is best to remove any damaged, diseased, or dead parts of the plant, making the cuts as close as possible to the healthy tissue. Pruning back the plant's growth can help renew the plant's vigor and encourage new growth.
Propagation of Draba asprella Greene var. typica C.L. Hitchc.
Draba asprella Greene var. typica C.L. Hitchc. is a perennial herb that belongs to the mustard family. It is native to the western United States, particularly in the Rocky Mountains region. The plant can grow up to 10 cm in height and has small white flowers that bloom from April to August. Propagation of Draba asprella Greene var. typica C.L. Hitchc. can be done through several methods.
Seed propagation
Seeds of Draba asprella Greene var. typica C.L. Hitchc. can be obtained from mature plants. The seeds need to be sown in individual pots or trays filled with well-draining soil, and kept in a cold frame or greenhouse for stratification. The ideal temperature for germination is 15-20°C, and germination usually occurs within 2-3 weeks.
Cuttings propagation
Draba asprella Greene var. typica C.L. Hitchc. can also be propagated through stem cuttings. This method is usually done in early summer, when the plant is actively growing. Cuttings should be taken from the newer growth and should be about 10 cm long. The cuttings should be dipped in rooting hormone before planting them in a well-draining soil mix.
Division propagation
Division propagation can also be used to propagate Draba asprella Greene var. typica C.L. Hitchc. This is done by dividing the plant during its dormant stage, usually in early spring or fall. The plant should be dug up and carefully separated into smaller clumps, ensuring that each clump has roots attached. The smaller clumps should be replanted in a well-draining soil mix.
Overall, Draba asprella Greene var. typica C.L. Hitchc. is a relatively easy plant to propagate, and can be propagated with seeds, cuttings, or division.
