This plant can also grow in poor soils, but it will not thrive. It is recommended to amend the soil with organic matter to provide additional nutrients.
Cultivation
Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston, commonly known as soft-haired popcorn flower, is a lovely plant that's easy to grow and maintain. It's a drought-tolerant plant and can thrive in poor soils. It prefers sunny areas but can tolerate some shade. It's best to plant it in the spring after the last frost.
The plant grows up to 12 inches tall and about 18 inches wide. It's a great option for rock gardens or as a low border plant. It attracts bees and butterflies, making it a great addition to any pollinator garden.
Watering Needs
Soft-haired popcorn flower is a drought-tolerant plant, but regular watering is necessary during the early stages of growth. Water the plant deeply once a week until it's well established. Once it's mature, it can survive on rainfall alone but will benefit from occasional watering during prolonged drought periods.
Fertilization
Soft-haired popcorn flower doesn't require fertilization if grown in fertile soil. However, if grown in poor soil, you can fertilize it in early spring with a light application of balanced fertilizer. Avoid over-fertilization as it can lead to weaker growth and fewer blooms.
Pruning
Soft-haired popcorn flower doesn't require extensive pruning. You can deadhead the spent blooms to promote more flowering throughout the season. The plant can also benefit from a light trimming in the fall to ensure a neat appearance. Avoid trimming too much, so the plant doesn't lose its natural shape.
Propagation of Plagiobothrys mollis var. vestitus
Plagiobothrys mollis var. vestitus, commonly known as soft popcornflower, can be propagated through various methods including seed propagation, stem cuttings, division, and layering.
Seed propagation
Soft popcornflower produces small seeds that can be collected and sown directly into the soil or started indoors in pots. The seeds should be sown in the fall or early spring in well-draining soil and kept moist until they germinate in 7 to 14 days.
Stem cuttings
Stem cuttings can be taken from the plant in the summer when the plant is actively growing. The cuttings should be about 4 inches long and taken from healthy, disease-free plants. The cuttings should be planted in a soil mixture of sand and peat moss and kept in a humid environment until they root in 3 to 6 weeks.
Division
Dividing the plant is another method of propagation for Plagiobothrys mollis var. vestitus. The plant should be dug up in the fall or early spring and divided into sections, each containing a portion of the root system and some foliage. The divided sections can be replanted in well-draining soil and kept moist until they establish roots.
Layering
Layering is a propagation method that involves bending a low-lying stem to the ground and burying a portion of it in the soil. The stem should be secured in place with a rock or stake and kept moist until roots develop from the buried portion of stem. Once the roots have formed, the stem can be cut from the parent plant and transplanted to its new location.
Disease Management for Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston
Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston is a hardy plant that is resistant to many diseases. However, certain diseases can still affect the plant, and it is best to take preventive measures to keep the plant healthy.
One of the most common diseases that can affect Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston is powdery mildew. Powdery mildew can be easily prevented by avoiding overhead watering and providing good air circulation. If powdery mildew is present, it can be treated with horticultural oil or a fungicide spray.
Another disease that can affect the plant is root rot. Root rot can occur if the plant is overwatered or if it is planted in poorly draining soil. The best way to prevent root rot is by ensuring that the soil is well-draining, and the plant is not overwatered. If root rot is present, it can be treated by removing the infected plant parts and treating the soil with a fungicide.
Pest Management for Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston
Plagiobothrys mollis (Gray) I.M. Johnston var. vestitus (Greene) I.M. Johnston is also a relatively pest-resistant plant. However, certain pests can still cause damage to the plant, especially if it is stressed or weakened.
