Light Requirements
Machaeranthera viscosa requires full sun exposure for optimal growth and development. It is a highly adaptable plant species, but it thrives in bright light conditions. Inadequate sunlight may lead to weak stems and an overall smaller size. Therefore, it is best to plant Machaeranthera viscosa in an open area that receives at least 6 hours of direct sunlight per day.
Temperature Requirements
This plant species prefers moderate temperatures in the range of 60-80°F (15-27°C). Although it can withstand occasional frosts in the winter, it does best in a warmer climate. Low temperatures can cause damage to the leaves and flowers, so it is important to avoid exposing Machaeranthera viscosa to extremely cold weather.
Soil Requirements
Machaeranthera viscosa can grow in a variety of soil types, including sandy, loamy, and rocky soils. However, the ideal soil for this species is well-drained, fertile soil that is slightly acidic to neutral (pH 6.0-7.5). It can tolerate drought conditions, but it requires occasional watering during dry periods to thrive. It is important to avoid waterlogged soil, as this can lead to root rot and other diseases.
Cultivation Methods
Machaeranthera viscosa, commonly known as Sticky Goldenweed, is a fast-growing plant that thrives in well-draining soils. It can be propagated either by seeds or stem cuttings. When planting from seeds, ensure the soil you use is moist and free of weeds. Sow the seeds at a depth of about 1/8 inch, and water the planted area regularly until the seedlings emerge. For stem cuttings, select a healthy and mature stem, cut it at an angle, and plant it in well-draining soil. Keep its soil moist but avoid overwatering.
Watering Needs
Machaeranthera viscosa requires moderate watering. During the hotter months, it is recommended to water it twice a week to maintain the soil's moisture level. In winter, however, the watering can be scaled back to once a week as the plant's growth slows down. Avoid over-watering as this can lead to root rot, which is likely to kill the plant
Fertilization
This plant does not require much fertilization, and it can do well with a well-balanced fertilizer applied once a month. Using a slow-release fertilizer is advised as it releases the nutrients slowly and for a more extended period. Do not fertilize during winter as the plant's growth slows down, and over-fertilizing can cause plant stress.
Pruning
Pruning is not necessary for Machaeranthera viscosa. However, it is recommended to trim off the spent flowers to promote new growth and encourage bushier growth. Also, pruning can be done to shape the plant as required. Choose the parts that seem straggly and may bring imbalance to the plant's shape and cut them off neatly with a clean pair of pruning shears.
Propagation of Machaeranthera viscosa (Nutt.) Greene
Machaeranthera viscosa (Nutt.) Greene is commonly known as sticky goldenweed. The plant can be propagated using different methods, including seeds, cuttings, and division.
Propagation by Seeds
Propagation by seeds is the most common method used to produce Machaeranthera viscosa. The seeds are relatively small and can be easily obtained from mature plants. The best time to collect the seeds is after the flowers have bloomed and the seed pods have started to dry. Seeds can be sown outdoors in the fall or early spring. The seeds should be planted in well-draining soil that has been enriched with organic matter. Water the seeds regularly and keep the soil moist until they germinate.
Propagation by Cuttings
Propagation by cuttings is another method used to produce Machaeranthera viscosa. The cuttings should be taken during early summer and should be around 3-4 inches in length. Remove the lower leaves and dip the cut end in rooting hormone before planting it in soil. Water the cutting regularly and keep it in a location with bright, indirect sunlight. The cutting should root within four to six weeks.
Propagation by Division
Propagation by division is a method used to reproduce Machaeranthera viscosa that has already been established. This method involves dividing the plant into sections and replanting them in separate pots. The best time to divide the plant is in late fall or early spring when the plant is dormant. Dig up the plant and gently separate the sections. Replant each section in a well-draining soil mix and water it regularly until it establishes itself.
Disease and Pest Management for Machaeranthera Viscosa
Machaeranthera viscosa (Nutt.) Greene is a hardy plant that belongs to the Asteraceae family. It is commonly referred to as the sticky purple aster because of its sticky hairy leaves and bright purple flowers. While this plant is resistant to many diseases and pests, it is still susceptible to some. Let's take a look at some common diseases and pests that might affect Machaeranthera viscosa and learn how to manage them.
Common Diseases
Machaeranthera viscosa is not known to be affected by many diseases. However, some fungal diseases can cause issues.
- Gray Mold: Gray mold is caused by the fungus Botrytis cinerea and can cause wilting and a grayish mold on the plant's leaves. To manage this disease, remove all affected plant parts and create good airflow around the plant.
- Root Rot: Root rot is caused by overwatering and can cause the plant to wilt and die. To manage this disease, make sure not to overwater and ensure proper soil drainage.
Common Pests
Machaeranthera viscosa is also relatively pest-resistant. However, some common pests can still thrive on this plant.
- Aphids: Aphids are small insects that feed on the plant sap and can cause yellowing and distortion of leaves. To manage these pests, hose off the plant with water and use insecticidal soap if necessary.
- Spider Mites: Spider mites are tiny insects that cause yellowing and webbing on plant leaves. To manage these pests, use an organic miticide or insecticidal soap.
Overall, Machaeranthera viscosa is a hardy plant that is relatively disease and pest-resistant. However, if you notice any issues with your plant, be sure to take action promptly to prevent the issue from spreading.
