Light
The plant Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin requires full sun to partial shade. It is adapted to grow in areas with long periods of daylight and short periods of darkness, which is typical of the Arctic region where it grows naturally.
Temperature
The plant Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin is adapted to grow in cold temperatures. It thrives in the Arctic region where temperatures can remain below freezing for long periods. The plant can withstand temperatures as low as -20°C. It is important to note that the plant requires a certain amount of temperature fluctuation throughout the year to properly flower.
Soil
The plant Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin grows best in well-draining soil that is free of salts. It requires moist soil but cannot tolerate waterlogging. The plant is adapted to grow in the Arctic region, which has low nutrient soil. Therefore, the plant requires little fertilizer and can grow in nutrient-poor soils.
Cultivation
Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin is a hardy plant that can tolerate the harsh conditions of the Arctic. It prefers well-drained soil and can grow in rocky areas. Gardeners can cultivate it in pots or in the ground.
Watering
Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin requires medium watering. Overwatering is not recommended as it can harm the plant. It is ideal to allow the top two inches of soil to dry out before watering the plant again. During the dormant season, this plant requires less water.
Fertilization
Fertilizing Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin is not necessary. However, if the plant is grown in pots or indoor, it may require a monthly dose of a weak, balanced fertilizer during the growing season. During the dormant season, avoid fertilizing the plant as it may hinder its growth.
Pruning
Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin does not require extensive pruning. However, gardeners can pinch off any dead or dying leaves to maintain its neat look. Additionally, cutting back the stem to promote bushy growth can be done in the beginning of the growing season.
Propagation of Braya humilis var. abbei
There are a few different methods for propagating Braya humilis var. abbei, including seed propagation, stem cuttings, and division.
Seed propagation
Seed propagation is the most common method for propagating Braya humilis var. abbei. Seeds should be collected from the plant in the fall and sown immediately or stored over the winter in a cool, dry place until spring. Seeds should be sown thinly in trays or pots filled with a well-draining seed-starting mix. The trays or pots should be kept in a cold frame or other sheltered position outside, where they can be exposed to fluctuating winter temperatures that will help to break down the seed coat. Germination typically occurs in the spring, and seedlings should be transplanted to their permanent location as soon as possible.
Stem cuttings
Stem cuttings can also be taken in late spring or early summer when the plant is actively growing. Select healthy, non-flowering stems and cut them just below a leaf node. Remove the lower leaves from the cutting and dip the cut end into rooting hormone powder. Place the cutting in a pot filled with a well-draining potting mix and keep it moist but not waterlogged. Cover the pot with a plastic bag to create a humid environment. The cutting should root within a few weeks, at which point the plastic bag can be removed and the new plant can be transplanted to its permanent location.
Division
Division is another method for propagating Braya humilis var. abbei. This method involves separating the plant's root ball into smaller sections and replanting them individually. This should only be done on mature plants that have become too large for their current location. Carefully dig up the plant and use a sharp knife or spade to separate the root ball into sections. Each section should contain some leaves and roots. Replant these sections immediately in their new location, making sure that the soil is well-draining and kept moist until new growth appears.
Disease and Pest Management for Braya humilis (C.A. Mey.) B.L. Robins. var. abbei (Böcher) Boivin
Although Braya humilis is a hardy, cold-climate plant that is resistant to many pests and diseases, it is not entirely immune. Here are some common diseases and pests that might affect Braya humilis, along with ways to manage them:
Diseases
Phytophthora root rot: This disease is caused by the Phytophthora fungus and leads to browning and rotting of the plant's roots. It can be controlled by improving soil drainage and avoiding over-watering. Treating with a fungicide can also help.
White rust: A fungus-like organism called Albugo candida causes this disease. It appears as white, powdery spots on the leaves. To prevent white rust, plant in well-drained soil and avoid overcrowding. Fungicides can also be used to treat the disease.
Black spot: This fungal disease causes black spots on the leaves. It can be controlled by removing infected leaves promptly. A copper-based fungicide can also be used.
Pests
Aphids: These small, green insects suck sap from the leaves, which can lead to stunted growth. They can be managed through the use of natural predators, such as ladybugs or lacewings, or through the application of insecticidal soap.
Cabbage looper: The larvae of this moth feed on the leaves of the plant and can cause extensive damage. Hand-picking the larvae is the most effective way to control infestations.
Wireworms: These are the larvae of click beetles and they feed on the roots of the plant, causing stunted growth and yellow leaves. Crop rotation and removing nearby grassy areas can help manage wireworms. Nematodes can also be applied to the soil to control their population.
