Uses
The Eastern dandelion has been used for various purposes. Its roots have been used as a natural remedy to treat liver and digestive problems, as well as for its diuretic properties. The leaves and flowers have been used in salads, and the plant has been brewed as a tea. Additionally, the Eastern dandelion has been used as a natural dye for fabrics.
General Appearance

The stem is hollow and produces a solitary yellow flower head that blooms from May to September. The flower head is composed of tiny yellow disk flowers and is surrounded by green bracts that fold downward during its blooming period.
Light Requirements
Taraxacum bessarabicum grows best in full sun to partial shade conditions. They require a minimum of 4-6 hours of sunlight each day to thrive. In shady conditions, their growth is slow and they may not produce flowers as frequently or abundantly.
Temperature Requirements
Taraxacum bessarabicum can grow in a wide range of temperatures. They can withstand frosts, but extreme heat and dry conditions can negatively affect their growth. The optimal temperature range for growth is between 15 to 25°C.
Soil Requirements
The soil for Taraxacum bessarabicum should be rich in nutrients and have good drainage. The pH range for the soil should be between 6 and 7.5, preferably neutral. They can tolerate a wide range of soil types, including clay, loam, and sand. It is important to note that these plants are highly adaptable to poor soil conditions, but they will not grow well in waterlogged soil.
Cultivation of Taraxacum bessarabicum
Taraxacum bessarabicum is a versatile plant that can be grown in several types of soil. However, it thrives best in well-drained, sandy loam soil with a pH between 6 and 7. To cultivate the plant, prepare the soil by tilling it to a depth of about eight inches and adding organic matter to improve the soil's composition and fertility.
Watering Needs
Taraxacum bessarabicum requires adequate water supply to grow and develop well. Water the plant deeply at least once per week to ensure that the roots receive enough moisture. However, ensure that the soil is not waterlogged as overwatering can lead to root rot. The plant's water needs may vary depending on the climatic conditions and the growth stage.
Fertilization
For the successful cultivation of Taraxacum bessarabicum, proper fertilization is crucial. Apply a balanced fertilizer, such as a 10-10-10 NPK fertilizer, during the growing season. Apply the fertilizer when the plant is actively growing but avoid fertilizing during dormancy. Over-fertilization can cause excessive vegetative growth at the expense of root development.
Pruning
Pruning is an essential aspect of maintaining the health of Taraxacum bessarabicum plants. Deadhead the spent flowers regularly to encourage more blooms and prevent the plant from self-seeding excessively. Additionally, thinning out the plant's canopy can increase light penetration and air circulation, promoting better plant health. Prune the plant in the early spring before new growth appears.
Propagation of Taraxacum bessarabicum
Taraxacum bessarabicum, also known as Bessarabian dandelion, is a herbaceous perennial plant that belongs to the Asteraceae family. It is native to Eastern Europe and known for its edible leaves and roots, which have medicinal properties.
Propagation from Seeds
The most common way to propagate Taraxacum bessarabicum is through seeds. The plant produces small, fluffy seeds that disperse easily in the wind. To grow the plant from seed, follow these steps:
- Collect the seeds when the plant has finished flowering and the seed heads have turned fluffy.
- Clean the seeds and store them in a cool, dry place until ready to plant.
- Sow the seeds directly into soil in the spring or fall.
- Keep the soil moist and warm until the seeds germinate, which can take two to three weeks.
Propagation from Division
Another way to propagate Taraxacum bessarabicum is through division. This method is best done in the spring or fall when the plant is dormant. Follow these steps:
- Choose a healthy plant and dig up the entire root system.
- Divide the root system into sections, making sure that each section has at least one shoot and a good amount of roots.
- Plant each section in a hole in the ground, making sure the crown is level with the soil surface.
- Water well and keep the soil moist until the plant becomes established.
Propagation from Cuttings
Propagation of Taraxacum bessarabicum from cuttings is less common but still possible. It is best done in the spring or early summer when the plant is actively growing. Follow these steps:
- Choose a healthy plant and cut off a 4-6 inch section of the stem.
- Remove the leaves from the bottom half of the cutting.
- Dip the cut end of the stem in rooting hormone.
- Plant the cutting in a pot filled with well-draining soil or directly in the ground.
- Keep the soil moist and warm until the cutting has rooted, which can take several weeks.
Overall, Taraxacum bessarabicum is an easy plant to propagate using any of these three methods. With proper care, it will grow into a healthy and productive plant that can be enjoyed for years to come.
Disease and Pest Management for Taraxacum bessarabicum
Taraxacum bessarabicum, also known as Ukrainian dandelion, is a plant species that is becoming popular for its potential to produce rubber. However, like any other plant, it is also prone to various diseases and pests that can affect its growth and yield. Here are some of the most common diseases and pests that might affect Taraxacum bessarabicum and the ways to manage them.
Diseases
Root Rot - Root rot is a fungal disease that attacks the roots of the plant and can cause wilting and death. The best way to prevent root rot is to make sure that the plant is not overwatered, and the soil is well-draining. If root rot is already present, remove the infected plant and replace the soil.
Leaf Spot - Leaf spot is a fungal disease that causes black or brown spots on the leaves of the plant. To manage leaf spot, remove the infected leaves and spray the plant with a fungicide. Make sure to keep the plant dry and avoid overhead watering.
Powdery Mildew - Powdery mildew is a fungal disease that causes a white powdery coating on the leaves of the plant. To manage powdery mildew, spray the plant with a fungicide and keep the plant dry. Make sure to avoid overcrowding, and provide proper air circulation to prevent the disease from spreading.
Pests
Aphids - Aphids are small insects that feed on the sap of the plant and can cause wilting and stunted growth. To manage aphids, spray the plant with insecticidal soap or neem oil. Make sure to remove any infected leaves and provide proper air circulation to prevent the infestation from spreading.
Slugs - Slugs are snail-like creatures that feed on the leaves of the plant. To manage slugs, handpick them from the plant and use a slug bait or a copper barrier to prevent them from feeding on the plant.
Cutworms - Cutworms are caterpillars that feed on the stem of the plant and can cause the plant to wilt and die. To manage cutworms, remove any infected plant and spray the area with insecticide. Make sure to avoid overwatering, as cutworms thrive in moist soil.
By paying close attention to the signs and symptoms of diseases and pests that might affect Taraxacum bessarabicum, you can take appropriate measures to prevent and manage them, thereby promoting the growth and yield of the plant.
