Too much fertilization can lead to excessive foliage growth and reduce flower production.Pruning
Onosmodium bejariense DC. ex A. DC. var. occidentale (Mackenzie) B.L. Turner requires minimal pruning. It is a low-maintenance plant that does not require systematic pruning. However, to encourage bushier growth, pruning should be done in the early spring when new growth appears. Deadheading spent flowers can also encourage the plant to produce more blooms. Pruning should not be done during the fall as it can damage the plant's winter hardiness.Propagation of Onosmodium bejariense DC. ex A. DC. var. occidentale (Mackenzie) B.L. Turner
Onosmodium bejariense DC. ex A. DC. var. occidentale (Mackenzie) B.L. Turner, commonly known as western marbleseed, is a perennial herb that grows in the western United States. Propagation of the plant can be achieved through several methods.
Seed Propagation
One way to propagate Onosmodium bejariense var. occidentale is by seed. The seeds can be collected from the plant when they are fully matured and have turned brown. The collected seeds can be stored in a cool, dry place until the appropriate planting time. The seeds can then be sown in well-drained soil that has been amended with organic matter. The soil should be kept moist, but not wet, until the seedlings emerge and established.
Division Propagation
Another way to propagate Onosmodium bejariense var. occidentale is through division. This method is best carried out in the early spring when the plant starts to show new growth. The root ball can be carefully dug up, and the plant can be separated into sections with a knife or sharp spade. Each section should have a healthy root system and a sufficient number of shoots.
Cuttings Propagation
Onosmodium bejariense var. occidentale can also be propagated through cuttings. This method is best carried out in the early spring or late fall. Cuttings should be taken from the top of the plant, and the leaves should be removed from the bottom of the cutting. The cuttings should be treated with rooting hormone and planted in well-drained soil that has been amended with organic matter. The soil should be kept moist, but not wet, until the cuttings have established roots.
Disease and Pest Management for Onosmodium bejariense var. occidentale
Onosmodium bejariense var. occidentale, commonly known as Western Marbleseed, is a native herbaceous perennial that grows in rocky soils and open forests of western North America. Although it is a hardy plant, it can be affected by several diseases and pests that need proper management to ensure its healthy growth and survival.
Common Diseases of Onosmodium bejariense var. occidentale
The following are some common diseases that can affect Onosmodium bejariense var. occidentale:
Leaf Spots
Leaf spot is a common fungal disease that affects the leaves of Onosmodium bejariense var. occidentale. The initial symptoms are small, dark spots that appear on the leaves, which can eventually lead to yellowing and defoliation. To manage this disease, it is essential to remove the infected leaves and keep the area clean and dry. Fungicides can also be applied as a preventive measure.
Powdery Mildew
Powdery mildew is another fungal disease that affects Onosmodium bejariense var. occidentale. It appears as a white powdery coating on the leaves, stem, and flowers. The infection can weaken the plant and reduce its yield, so proper management is crucial. Fungicides and cultural practices such as adequate spacing, pruning, and air circulation can help prevent and manage powdery mildew.
Common Pests of Onosmodium bejariense var. occidentale
Onosmodium bejariense var. occidentale can also be affected by several pests, including:
Aphids
Aphids are small, soft-bodied insects that suck the sap from the leaves, flowers, and stems of the plant, causing curling and deformation. In severe infestations, they can weaken the plant and transmit viral diseases. To manage aphids, it is essential to remove the affected parts and apply insecticidal soap or neem oil.
Spider Mites
Spider mites are tiny pests that feed on the sap of the plant, causing yellowing, discoloration, and defoliation. They thrive in hot and dry conditions, so watering and spraying the plant regularly with water can help prevent their infestation. Insecticidal soap and neem oil are also effective in managing spider mites.
