The plant can also tolerate poor soils but prefers an organically rich soil that is amended with compost or aged manure. The plant grows best in sandy or loamy soils that retain moisture but do not become waterlogged. Vigorous drainage is essential to prevent root rot, which may damage the plant's growth.
Cultivation Methods
Arabis divaricarpa A. Nels. var. dacotica (Greene) Boivin is a hardy perennial plant that can grow in a wide range of soils. It prefers well-draining soil with a pH range of 6.0 to 7.5. It can tolerate full sun to partial shade and grows well in USDA hardiness zones 3 through 7.
The best time to plant this plant is in the spring or fall. You can propagate this plant by collecting seeds, taking stem cuttings, or dividing the root ball. Once planted, provide the plant with adequate water and mulch to retain moisture.
Watering Needs
Arabis divaricarpa A. Nels. var. dacotica (Greene) Boivin prefers moderate watering. Water the plant regularly but do not overwater it. Overwatering can lead to root rot and other diseases. Allow the soil to dry slightly between watering. Provide adequate water during hot summer months and drought conditions.
Fertilization
Arabis divaricarpa A. Nels. var. dacotica (Greene) Boivin does not require heavy fertilization. Fertilize once a year in the spring with a slow-release fertilizer. Avoid using chemical fertilizers as it can damage the plant.
Pruning

Propagation of Arabis divaricarpa var. dacotica
Arabis divaricarpa var. dacotica is a flowering plant native to North America and commonly known as Dakota rockcress or Spreading rockcress. It belongs to the Brassicaceae family and is characterized by its small white or pink flowers, basal rosettes, and deeply lobed leaves.
There are several propagation methods that can be used to propagate Arabis divaricarpa var. dacotica:
1. Seed propagation
One of the most common propagation methods for Arabis divaricarpa var. dacotica is by seed. Seeds should be collected from mature plants in the fall or early spring. The seeds require a period of stratification to break dormancy and should be stored in a cool, dry place until planting in the spring.
To plant the seeds, the soil should be moistened, and the seeds should be sprinkled on the surface, then lightly covered with soil. The seeds will germinate in two to three weeks, and the seedlings can be transplanted once they have developed their first true leaves.
2. Vegetative propagation
Another propagation method for Arabis divaricarpa var. dacotica is through vegetative propagation. This involves taking cuttings from the parent plant and rooting them in soil.
To take a cutting, select a healthy, non-flowering stem and cut a 4- to 6-inch section. Remove the lower leaves, and dip the cut end in rooting hormone. Place the cutting in a container filled with moist soil, and cover it with a plastic bag to retain moisture. Rooting should occur in four to six weeks and the new plant can be transplanted when it has established roots.
3. Division
Division is another propagation method for Arabis divaricarpa var. dacotica that can be used to increase the number of plants. This method is best done in the spring when the plant is actively growing.
To divide the plant, dig up the entire plant and separate the crown and root system into sections. Each section should have several stems and a healthy root system. Replant the sections in a well-draining soil mixture and water until established.
