Common Names
Bidens frondosa L. var. puberula Wieg. is commonly known as Hairy beggarticks, Devil's sticktight, Needle-grass, Swamp beggarticks, and Cuckoo's-feet. The plant is called "beggarticks" because of its tendency to stick to clothing and animal fur, while "Devil's sticktight" refers to the plant's ability to cling onto surfaces.
Light Requirements
Bidens frondosa L. var. puberula Wieg. requires full sun to partial shade to grow properly. It is best to plant the seeds in areas where they can get a minimum of 6 hours of sunlight every day. If planting in areas that receive intense sunlight, ensure that the soil is moist enough to prevent the plant from drying up.
Soil Requirements
The plant requires soil that is well-draining and fertile. The soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.0. Adding organic matter to the soil, such as compost or well-rotted manure, can boost soil fertility and improve moisture retention. Bidens frondosa L. var. puberula Wieg. does not tolerate heavy, compacted soils. Therefore, aerating the soil before planting may be necessary.
Temperature Requirements
Bidens frondosa L. var. puberula Wieg. thrives in warm temperatures. The ideal temperature range for growth is between 60°F to 85°F (15.5°C to 29.4°C). Temperatures below 50°F (10°C) can damage young plants and delay growth. In regions with frost, the plant may not survive the winter season. Therefore, planting in spring or late summer is best to ensure that the plant has enough time to grow before the arrival of the cold season.
Cultivation
Bidens frondosa L. var. puberula Wieg. can be grown in a wide range of soils including sandy, loamy, and clay soils. It thrives in well-drained, fertile soils enriched with organic matter. The plant prefers full sun to partial shade for optimal growth. It can tolerate mild frost but cannot withstand extreme cold during the winter.
Watering Needs
Bidens frondosa L. var. puberula Wieg. requires regular watering, especially during the hot and dry periods of the year. The soil should be kept consistently moist but not waterlogged to avoid waterlogging and root rot. The plant requires about 1-2 inches of water per week from either rainfall or irrigation.
Fertilization
Bidens frondosa L. var. puberula Wieg. is not a heavy feeder, but regular fertilization is essential to promote healthy growth and flowering. A balanced fertilizer that contains equal portions of nitrogen, phosphorus, and potassium is ideal for the plant. The fertilizer should be applied twice a year, in early spring and late summer.
Pruning
Bidens frondosa L. var. puberula Wieg. requires minimal pruning to maintain its shape and appearance. Deadheading of spent blooms can encourage more flowers to appear throughout the growing season. However, excessive pruning of the plant can lead to stunted growth and reduced flowering.
Propagation of Bidens frondosa L. var. puberula Wieg.
Bidens frondosa L. var. puberula Wieg., commonly known as Hairy Beggarticks, is a herbaceous plant that belongs to the Asteraceae family. It originates from eastern and central North America and is predominantly found in meadows, pastures, and along roadsides. Propagation of this plant can be achieved through various methods.
Seed Propagation
The primary method of propagating Hairy Beggarticks is through seeds. Seeds of this plant can be collected in late summer or early fall when the seed heads have turned brown. The collected seeds should be stored in a cool and dry place until planting.
To propagate the plant from seeds, prepare the seedbed by loosening the soil. Sow the seeds on the surface of the soil and cover them with a thin layer of soil. Water the seedbed immediately after planting and keep the soil moist until the seeds germinate.
Seedlings should be thinned to a spacing of 12 to 18 inches apart to allow the plants to grow to their full potential. Hairy Beggarticks will bloom in their first year after seed propagation.
Vegetative Propagation
Hairy Beggarticks can also be propagated through vegetative means such as stem cuttings and division.
Stem cuttings can be taken in late spring or early summer when new growth is present. Cut a 2-3 inch stem that is free of flowers and buds. Remove the lower leaves, leaving only a few at the top. Plant the cutting in a rooting medium and keep it moist until the roots and new growth emerge.
Division of Hairy Beggarticks is possible but is not the most effective method. The plant should be dug up and divided into sections in spring or fall. Each section should contain at least one shoot and a good root system. Replant the divided sections immediately, keeping the soil moist.
By implementing these propagation methods, Hairy Beggarticks can be easily propagated and grown in a variety of settings.
Disease and Pest Management for Bidens frondosa L. var. puberula Wieg.
Bidens frondosa L. var. puberula Wieg. is generally a hardy plant that is not susceptible to many diseases or pests. However, there are a few common problems that can occur and it's important to be aware of them in order to manage them effectively.
Diseases
One of the most common diseases that can affect Bidens frondosa is powdery mildew. This fungal disease appears as a white or gray powdery coating on the leaves, stems, and flowers of the plant. To manage powdery mildew, it's important to keep the plant well-ventilated and to avoid getting the leaves wet when watering. In severe cases, it may be necessary to apply a fungicide.
Anthrax is another potential disease that can affect Bidens frondosa. This bacterial disease causes yellowing and wilting of the leaves, as well as dark spots on the stem. To manage anthrax, it's important to remove any affected plant parts and to avoid overcrowding plants as this can increase the risk of infection.
Pests
One of the most common pests that can affect Bidens frondosa is the leafhopper. These small insects feed on the sap of the plant, causing leaves to turn yellow and eventually die. To manage leafhoppers, it's important to keep the plant well-watered as stressed plants are more susceptible to infestations. It may also be necessary to use an insecticide to control the population.
Another pest that can affect Bidens frondosa is the aphid. These small insects also feed on the sap of the plant and can cause stunted growth, curled leaves, and a general decline in plant health. To manage aphids, it's important to keep the plant well-watered and to introduce natural predators such as ladybugs or lacewings. In severe cases, it may be necessary to use an insecticide.
Conclusion
Overall, Bidens frondosa L. var. puberula Wieg. is a hardy plant that is not susceptible to many diseases or pests. However, it's important to be aware of the potential problems and to manage them effectively in order to maintain the health and beauty of the plant.
