The hollow stem of the plant can reach up to 50 cm in height. The flower heads are yellow and are composed of numerous tiny yellow petals. The plant's fruit is a small, brownish achene with a tuft of white hairs.
Uses
The plant has a variety of traditional medicinal uses. In Siberia, it has been used to treat a range of ailments, including stomach disorders and respiratory problems. The plant is also used in traditional Chinese medicine, where it is believed to have anti-inflammatory and antitumor properties. The leaves and roots of the plant have also been used as a food source in some regions, either raw or cooked.
Growth Conditions for Taraxacum lyratum (Ledeb.) DC.
Taraxacum lyratum (Ledeb.) DC. is a perennial plant species that belongs to the family Asteraceae. It is an herbaceous plant that grows up to 50 cm tall with linear leaves and yellow flowers. The plant is known for its medicinal properties and is used for treating various diseases.
Light Requirements
Taraxacum lyratum (Ledeb.) DC. requires full sunlight for its growth. It is a sun-loving plant that needs at least six hours of direct sunlight every day. Inadequate sunlight can cause stunted growth and poor flowering. Therefore, the plant should be grown in a location that receives full sunlight without any obstruction.
Temperature Requirements
Taraxacum lyratum (Ledeb.) DC. is a hardy plant that can tolerate a wide range of temperatures. However, the ideal temperature for its growth is between 18°C to 25°C. Temperatures lower than 5°C and higher than 30°C can hamper the plant's growth. The plant should be protected from frost and extreme heat to prevent damage.
Soil Requirements
Taraxacum lyratum (Ledeb.) DC. can grow in a variety of soils, but it prefers well-draining soil that is rich in organic matter. The soil pH should be between 6.0 to 7.5, which is slightly acidic to neutral. The plant cannot tolerate waterlogged soil, so the soil should be well-drained to prevent waterlogging. The plant can also grow in poor soil conditions, but it would require frequent fertilizing.
Cultivation Methods
Taraxacum lyratum (Ledeb.) DC. commonly known as the dandelion, can grow in a variety of soil types as long as it is well-drained. It can be propagated by either seed or division of crowns. Plant the seeds or seedlings at a depth of ¼ inch and give them enough space to grow, usually 6-12 inches apart. Dandelions are very hardy and can survive in both sun and shade conditions.
Watering Needs
Dandelions require regular watering, particularly when they are young and establishing roots. They also require consistent moisture throughout their growing season. Watering once a week should be sufficient, but more frequent watering may be necessary during long, dry spells.
Fertilization
Dandelions do not require a lot of fertilization, but it is beneficial to add compost or other organic matter to the soil before planting. This will provide the necessary nutrients to encourage healthy growth. Additionally, a balanced fertilizer with equal amounts of nitrogen, phosphorous, and potassium can be applied in early spring to promote growth and flowering.
Pruning
Pruning is not required for dandelions as they grow low to the ground and maintain their shape fairly well. However, deadheading (removing spent flowers) can promote additional blooms and prevent the plant from going to seed too quickly. If the plant becomes too large or out of control, it can be trimmed back in the fall after it has finished blooming.
Propagation of Taraxacum lyratum (Ledeb.) DC.
Taraxacum lyratum (Ledeb.) DC. is a perennial herb that belongs to the Asteraceae family. It is commonly known as the Armenian dandelion. The plant produces a rosette of basal leaves and yellow flowers on erect stems. It is mainly propagated through seeds, but vegetative propagation is also possible.
Seed Propagation
The most common method for propagating Taraxacum lyratum is by seed. Seeds can be collected from mature plants by waiting for the flower heads to dry and then collecting the pappus-bearing fruits. The seeds should be cleaned and stored in a cool, dry place until ready for planting. The best time to sow the seeds is in early spring or autumn. The seeds should be sown thinly in prepared soil and covered with a thin layer of compost or vermiculite. The soil should be kept moist but not waterlogged, and the seedlings should be thinned out once they reach a suitable size.
Vegetative Propagation
Vegetative propagation of Taraxacum lyratum is also possible but less common. This method involves using plant parts other than seeds, such as root cuttings or runners. Root cuttings should be taken from mature plants during the dormant season. The cuttings should be about 2-3 inches long and planted in compost-rich soil, keeping the soil moist until new growth appears. Runners can be taken from mature plants during the growing season and planted in soil after they have developed roots. Vegetative propagation is advantageous because it can produce genetically identical plants, but it is more labor-intensive and time-consuming compared to seed propagation.
In conclusion, Taraxacum lyratum (Ledeb.) DC. can be propagated by seeds or vegetative methods such as root cuttings or runners. Seed propagation is faster and less labour-intensive, but vegetative propagation can produce identical plants. Regardless of the propagation method used, it is important to maintain optimal growing conditions to ensure the best chances of success.
Disease Management
Taraxacum lyratum (Ledeb.) DC. is a robust plant that is relatively resistant to disease, but it can still be affected by some common diseases. Here are the most common diseases that affect Taraxacum lyratum (Ledeb.) DC.:
Leaf spot: Leaf spot is a fungal disease that causes black or brown spots on the leaves of the plant. To manage this disease, it is essential to remove and destroy the infected leaves periodically. Fungicides can also be used to control leaf spot disease.
Rust: Rust is another fungal disease that causes yellow or orange spots on the leaves of the plant. Rust usually affects plants grown in humid conditions. To manage this disease, it is important to remove and destroy the infected leaves and provide adequate ventilation to reduce humidity.
Mosaic virus: Mosaic virus causes yellow mottling or distortion of the leaves of the plant. There is no cure for this viral disease, so infected plants should be removed and destroyed immediately to prevent the spread of the disease to healthy plants
Pest Management
Taraxacum lyratum (Ledeb.) DC. is infrequently attacked by pests; however, it can still be susceptible to some pests that can cause damage to the plant. Here are the most common pests that affect Taraxacum lyratum (Ledeb.) DC.:
Aphids: Aphids are soft-bodied insects that feed on the sap of the plant. They can cause stunted growth and yellowing of the leaves. To manage aphids, it is vital to remove them by hand or treat the plant with insecticides.
Slugs and snails: Slugs and snails feed on the leaves of the plant. To manage these pests, it is important to handpick them or use baits such as beer traps.
Caterpillars: Caterpillars can cause significant damage to the leaves of the plant by feeding on them. To manage caterpillars, it is vital to remove them by hand or treat the plant with insecticides.
Implementing preventive measures, such as maintaining the health of the plant by watering and fertilizing it appropriately, can go a long way in preventing pests and diseases from attacking Taraxacum lyratum (Ledeb.) DC.
