Cultivation methods for Machaeranthera canescens
Machaeranthera canescens, commonly known as Hoary Tansyaster, is a native plant of North America. It is a hardy, perennial plant that requires well-drained soil and full sunlight to grow. You can cultivate it either from seeds or by transplanting a mature plant to your garden.
Watering needs for Machaeranthera canescens
Since Machaeranthera canescens is a drought-tolerant plant, it does not require frequent watering. Water it only when the top inches of soil have dried out, which should be limited to once or twice a week. Ensure that you do not overwater it as it can lead to root rot.
Fertilization for Machaeranthera canescens

Trim any dead, damaged, or diseased branches using pruning shears. If you want to promote more blooms, you can deadhead the spent flowers throughout the growing season.
Propagation of Machaeranthera canescens var. latifolia
Machaeranthera canescens var. latifolia can be propagated via seed or vegetative methods such as division and stem cuttings.
Seed Propagation
The seeds of Machaeranthera canescens var. latifolia can be directly sowed into well-drained soil in the spring or fall. The seeds should be pressed lightly into the soil and covered with a thin layer of vermiculite. The soil should be kept moist until the seeds germinate, which can take up to three weeks. Once the seedlings have a few sets of true leaves, they can be transplanted to their permanent location.
Division
Division is a method of propagation that involves separating a mature plant into several smaller plants. To propagate Machaeranthera canescens var. latifolia via division, carefully dig up the plant in the spring or fall. Gently separate the individual clumps and replant them in a well-draining soil mix. Water the newly transplanted divisions frequently until they become established.
Stem Cuttings
Stem cuttings is a propagation method that involves taking a cutting from a mature plant and rooting it. Take a cutting from a healthy, mature plant in the spring or summer. The cutting should be about 3-4 inches in length and have several sets of leaves. Remove the bottom sets of leaves and dip the cut end of the stem into rooting hormone. Plant the cutting into a well-draining soil mix and keep the soil moist until it becomes established.
Disease and Pest Management for Machaeranthera canescens (Pursh) Gray var. latifolia (A. Nels.) Welsh
Machaeranthera canescens (Pursh) Gray var. latifolia (A. Nels.) Welsh is relatively resistant to diseases and pests. However, there are still some common issues that can affect the plant. Here are some important disease and pest management strategies to keep in mind:
Diseases
One of the main diseases that can affect Machaeranthera canescens (Pursh) Gray var. latifolia (A. Nels.) Welsh is rust. Rust is a fungal disease that causes orange or brown spots on the foliage of the plant. To manage rust, it is important to remove and destroy any infected plant material, as the spores can survive on dead plant material. Additionally, providing good ventilation and spacing the plants out can help to prevent the disease from spreading.
Another disease that can affect the plant is powdery mildew. Powdery mildew is a fungal disease that causes a white or gray powdery coating on the leaves and stems of the plant. To manage powdery mildew, it is important to remove and destroy any infected plant material, and to improve air circulation around the plant by spacing them out. Additionally, spraying the plant with a fungicide can help to control the disease.
Pests
One of the most common pests that can affect Machaeranthera canescens (Pursh) Gray var. latifolia (A. Nels.) Welsh is aphids. Aphids are small, soft-bodied insects that feed on the sap of the plant, causing stunted growth and distorted foliage. To manage aphids, it is important to remove them from the plant using a strong stream of water from a hose or by using an insecticidal soap or oil. Additionally, attracting beneficial insects such as ladybugs and lacewings can help to control aphid populations.
Spider mites are another common pest that can affect the plant. Spider mites are tiny, red or green insects that feed on the undersides of leaves, causing a stippling or discoloration. To manage spider mites, the plants should be monitored regularly, and any signs of infestation should be treated immediately with a miticide. Additionally, providing good air circulation can help to prevent spider mites from becoming a problem.
By following these disease and pest management strategies, you can help to ensure that your Machaeranthera canescens (Pursh) Gray var. latifolia (A. Nels.) Welsh remains healthy and productive.
