Light Requirements
The Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins plant is a sun-loving plant and requires full sunlight for its growth and development. It can tolerate partial shade but the plant may have inadequate growth with a lack of sufficient sunlight. Therefore, it is recommended to plant the Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins plant in a location that receives full sunlight for at least 6 hours per day to ensure optimal growth and flowering.
Temperature Requirements
The Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins plant is adaptable to a wide range of temperatures and can grow in both hot and cold climates. The plant can withstand extreme temperatures ranging from -34°C to 43°C but thrives optimally in a temperature range between 15 – 26°C. The plant’s growth is slowed down or stunted when subjected to temperature extremes for a prolonged period of time. A warm climate with a cool night is ideal for this plant’s growth and development.
Soil Requirements
The Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins plant prefers a well-draining soil type that is rich in organic matter. The plant thrives best in a slightly acidic to neutral soil pH ranging between 6.0 – 7.2. This plant is adaptable to different soil types including sandy, loamy, and clay. Similarly, the plant prefers a moist soil environment but is drought-tolerant. Therefore, it is crucial to ensure that the plant is watered regularly but not excessively. Additionally, the addition of organic matter to the soil before planting helps to improve soil texture, fertility, and water-holding capacity, which leads to optimal plant growth and development.
Cultivation Methods
Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins is a perennial plant that is native to California. The plant prefers full sun to partial shade and well-drained soils. It requires moderate watering during the growing season and little watering in the dormant season.
Propagation of the plant can be done through seeds or cuttings. Seeds can be directly sown in the soil or started indoors and transplanted when the seedlings reach 3-4 inches. Cuttings can be taken in the spring when stem tips are soft but not yet woody. Place the cuttings in a rooting hormone and plant them in well-drained soil.
Watering Needs
Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins has moderate water needs during the growing season. The plant should be watered when the top layer of soil is dry to the touch. Overwatering can lead to root rot and other issues. In the dormant season, the plant requires little watering.
Fertilization
The plant benefits from the application of a slow-release fertilizer in the spring. A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable. Follow the instructions on the fertilizer packaging for the appropriate application rate.
Pruning
Pruning is not necessary for this plant, but it can be done in the spring to encourage bushier growth. Prune back the stems by one-third to one-half their length. Deadheading spent flowers can also promote continued blooming throughout the season.
Propagation Methods for Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins
Propagation of Arabis pycnocarpa M. Hopkins var. adpressipilis M. Hopkins, commonly known as the Spreading Rockcress, can be done using several methods, including:
Seed Propagation
Seeds can be sown directly into the garden bed or started indoors in trays. To improve germination rates, soak the seeds in water for 24 hours before planting. Cover the seeds lightly with soil and ensure that the soil remains moist until germination occurs.
Cuttings Propagation
Propagation by cuttings may produce faster results than seed propagation, but the success rate may vary. Take softwood cuttings in the spring or semi-hardwood cuttings in fall, dip them in rooting hormone, and insert them into well-draining soil. Cuttings will root within a few weeks, and they can be transplanted into a permanent location.
Division Propagation
Propagation by division can be done in early spring or fall when the plant is not actively growing. Dig up the plant and separate the root clumps, making sure each division has some roots and several shoots. Replant the divisions in a well-draining soil mix and water them thoroughly.
