Light Requirements
Phlox subulata L. ssp. brittonii (Small) Wherry commonly grows in full sun to partial shade. It needs at least 6 hours of direct sunlight per day to thrive. However, in hotter regions, it can benefit from afternoon shade to prevent the leaves from burning.
Temperature Requirements
This plant is hardy and adapts well to different weather conditions. It can tolerate cold temperatures and can survive winters in USDA zones 3-9. The optimal temperature range for Phlox subulata L. ssp. brittonii (Small) Wherry growth is between 50 and 80 degrees Fahrenheit.
Soil Requirements
This plant prefers well-draining soil that is rich in organic matter. The soil pH level should be slightly acidic to neutral, ranging from 5.5 to 7.0. It can grow in sandy or rocky soil, but the addition of compost or organic matter can improve soil fertility.
Cultivation
Phlox subulata L. ssp. brittonii (Small) Wherry is a low-growing, mat-forming perennial that prefers well-drained soil and full sunlight. It is tolerant of drought, poor soil conditions, and colder temperatures, making it suitable for growth in the USDA hardiness zones 3 to 9.
Propagation can be done by division of mature plants in spring or by seed sowing indoors in late winter.
Watering Needs
Phlox subulata L. ssp. brittonii (Small) Wherry prefers medium moisture levels in the soil and is moderately drought tolerant. It is essential not to overwater the plant as it can lead to root rot.
Watering the plant once a week, providing an inch of water, can keep the plant sufficiently hydrated. However, during dry periods, it may require more frequent watering.
Fertilization
Phlox subulata L. ssp. brittonii (Small) Wherry does not require frequent fertilization. In early spring, a slow-release fertilizer can be incorporated into the soil to enhance growth and development. Alternatively, a balanced liquid fertilizer can be applied every 4-6 weeks during the active growing season.
Pruning
Cutting back Phlox subulata L. ssp. brittonii (Small) Wherry after flowering in late spring or early summer can enhance its appearance, encourage vigorous growth, and promote reblooming. Deadheading also helps to prevent the plant from setting seed and redirects its energy towards the production of new growth and flowers.
It is also recommended to thin out old, woody growth and remove any yellow or dead foliage to promote new shoots and a healthy appearance of the plant.
Propagation of Phlox subulata L. ssp. brittonii (Small) Wherry
Phlox subulata L. ssp. brittonii, commonly known as Britton's creeping phlox or mountain phlox, is a herbaceous perennial plant native to North America. It is a popular garden plant due to its attractive appearance and ability to withstand harsh growing conditions.
Propagation of Phlox subulata L. ssp. brittonii can be done through several methods, including seed propagation, division, and stem cuttings.
Seed Propagation
Phlox subulata L. ssp. brittonii can be propagated from seeds, which can be sown indoors in late winter or directly in the garden after the last frost. The seeds should be lightly covered with soil and kept moist until germination, which usually takes about 2-3 weeks. Once the seedlings have developed their second set of true leaves, they can be transplanted to their permanent location in the garden.
Division
Division is another method of propagating Phlox subulata L. ssp. brittonii. It is best to divide the plant in early spring before new growth appears or in the fall after blooming has ended. The plant should be lifted carefully and the root system divided into several clumps. Each clump should have some roots and foliage, then replanted in a new location with well-draining soil.
Stem Cuttings
Stem cuttings can also be used to propagate Phlox subulata L. ssp. brittonii. The cuttings should be taken from new growth in the spring when the plant is actively growing. Using a sharp knife, cut a 4-6 inch section of stem just below a node and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with a well-draining potting mix. Keep the soil moist and place the pot in a warm, brightly lit area. Roots should begin to develop in 2-4 weeks, at which point the new plant can be transplanted to a permanent location in the garden.
Disease Management
Phlox subulata L. ssp. brittonii is susceptible to various diseases that can negatively impact its growth and overall health. Below are some of the common diseases affecting this plant and ways to manage them:
Phytophthora Root Rot
Phytophthora root rot is a fungal disease that affects the roots of the plant. It can cause the plant to wilt, turn yellow, and eventually die. To manage this disease, ensure proper drainage in the soil and avoid overwatering. Fungicide applications may also help in controlling the disease.
Botrytis Blight
Botrytis blight is a fungal disease that affects the leaves and flowers of the plant. It causes greyish-brown spots on the leaves and petals, leading to withering and eventual death. To manage this disease, remove infected plant parts and ensure proper air circulation to prevent high humidity. Fungicide applications may also help in controlling the disease.
Verticillium Wilt
Verticillium wilt is a fungal disease that affects the plant's vascular system, causing wilting and yellowing of the leaves. It may also cause stunted growth and eventual death of the plant. To manage this disease, remove infected plant parts and avoid replanting phlox in the same soil where wilt disease has occurred. Fungicide applications may also help in controlling the disease.
Pest Management
Phlox subulata L. ssp. brittonii is also vulnerable to various pests. Below are some of the common pests infesting this plant and ways to manage them:
Spider Mites
Spider mites are tiny pests that suck sap from the leaves, resulting in yellowing and brown spots. They also produce webs, giving the plant a dusty appearance. To manage this pest, wash the plant with a mild soap solution or blast it with water. In severe cases, apply an insecticide.
Aphids
Aphids are small, soft-bodied insects that suck sap from the leaves, causing curling, yellowing, and distortion. They also produce honeydew, attracting ants and other pests. To manage this pest, wash the plant with a mild soap solution or blast it with water. In severe cases, apply an insecticide.
Leafhoppers
Leafhoppers are small, wedge-shaped insects that hop around when disturbed. They suck sap from the leaves, causing yellowing and stunted growth. They also transmit viruses, causing yellowing and mottling of the leaves. To manage this pest, wash the plant with a mild soap solution or blast it with water. In severe cases, apply an insecticide.
