Light Requirements
Arabis cuneifolia grows best in full sun to partial shade. It needs at least six hours of direct sunlight a day to thrive. If the plant is grown in too much shade, it may become leggy and not produce as many flowers.
Temperature Requirements
This plant requires a cool to moderate temperature to thrive. In hot weather, it may become stressed and wilt. It prefers to grow in temperatures between 60 and 75 degrees Fahrenheit (15.5-24°C). In warmer climates, it is best to plant the Arabis cuneifolia in a location that provides afternoon shade.
Soil Requirements
The Arabis cuneifolia prefers well-draining soil that is slightly acidic with a pH range of 5.5 to 6.5. It can grow in a variety of soil types, but it does best in sandy or loamy soil. If the soil is too heavy or compacted, it may cause the plant to develop root rot. It is important to amend the soil with organic matter to improve drainage, which will promote healthy root development.
Additionally, the soil should be kept evenly moist but not soggy. Overwatering can lead to fungal diseases and root rot, which can kill the plant. Regular watering during dry periods is essential for the plant's health.
Cultivation
Arabis cuneifolia Hochst. ex A.Rich. is a low-growing plant that grows best in well-draining soil. The plant can tolerate a range of soil types but prefers slightly acidic to neutral soil. It grows well in full sun but can tolerate some shade.
The best time to plant Arabis cuneifolia is in spring, once the danger of frost has passed. Plant the seedlings at least 12 inches apart to allow enough room for growth.
Watering Needs
Arabis cuneifolia prefers moist soil but can tolerate short periods of drought. Regular watering is necessary during the plant's growing season. Once established, the plant can survive on rainfall, but it is best to water it during extended droughts or when the soil feels dry to the touch.
Fertilization
Arabis cuneifolia does not require heavy fertilizer application. However, a light application of fertilizer in early spring can promote healthy growth. Use a balanced fertilizer with an equal ratio of nitrogen, phosphorus, and potassium. Follow the manufacturer's instructions for application rates and timing.
Pruning
Arabis cuneifolia is a low-maintenance plant that does not require much pruning. Deadhead the plant regularly to promote continuous blooming. After blooming, cut back the stems to encourage new growth and bushier habit. You can also trim back the plant after winter to remove any damaged or dead growth.
Propagation of Arabis cuneifolia Hochst. ex A.Rich.
Arabis cuneifolia Hochst. ex A.Rich. can be propagated through a variety of methods such as seeds, cuttings, and division.

Propagation by Cuttings
Propagation by stem cuttings is also possible. Take cuttings from the plant during the growing season and plant them in rooting medium with good drainage. Keep the cuttings moist and provide them with bright light. When roots have formed, transplant them into a pot or the garden.
Propagation by Division
Propagation by division is also possible. Divide clumps in the early spring before growth begins. Dig up the clumps and separate them into smaller plants which can be planted in well-draining soil. Water the newly transplanted divisions well, and provide them with good sunlight.
With proper care and attention, Arabis cuneifolia Hochst. ex A.Rich. can be easily propagated through seeds, cuttings, and division.
