Bidens heterophylla Ortega or Beggars tick requires a minimum of 6 hours of direct sunlight per day. They grow best in full sun exposure, but they can tolerate partial shade from taller plants during the day.
Temperature Requirements
These type of plants are native to North America and they can tolerate a wide range of temperatures ranging from -12.2? to 40?. They thrive better in temperatures between 21? and 26?, which is optimal for their growth and development.
Soil Requirements
Bidens heterophylla prefers moist and well-draining soils. Although they can tolerate various soil types from sandy to clayey soils, they perform excellently in rich loam soil. It is essential to maintain a slightly acidic pH level between 6.0 and 6.5 to prevent nutrient deficiencies.
Cultivation Methods
Bidens heterophylla Ortega, also known as Bidens pilosa, is an easy-to-grow annual plant that thrives in full sun or partial shade and well-drained soil. The seeds of the plant can be sown directly outdoors in spring or fall, or they can be started indoors in early spring and transplanted outdoors after the last frost. The plant grows well in containers, raised beds, or on the ground, and it has a mature height of between 1 to 3 feet.
Watering Needs
Bidens heterophylla Ortega requires regular watering to keep the soil moist, but not waterlogged. During the hot and dry summer months, the plant may need watering at least twice a week. A good practice is to water the plant in the morning or late afternoon to avoid evaporation and fungal diseases. Additionally, it is important to avoid getting water on the foliage, as this can lead to fungal attacks and disease.
Fertilization
Bidens heterophylla Ortega is not a heavy feeder, so fertilization requirements are generally minimal. However, supplementing with a general-purpose fertilizer during the initial planting and then every 4-6 weeks can keep the plant healthy and enhance flowering. Organic compost or well-rotted manure can also be added to the soil in spring to boost nutrient levels and improve soil structure.
Pruning
Bidens heterophylla Ortega does not require extensive pruning. However, deadheading or removing dead flowers regularly promotes continuous flowering and improves the plant's overall appearance. Pruning can also be done to control the size and shape of the plant, though this should be done sparingly. Use clean, sharp pruning shears and cut back the plants' stem just above a healthy leaf node.
Propagation of Bidens Heterophylla Ortega Plant
Bidens heterophylla Ortega, also known as the showy tickseed sunflower, is a perennial plant that belongs to the Asteraceae family. Propagation of this plant can be done through seed and vegetative cuttings.
Propagation by Seed
The easiest method to propagate Bidens heterophylla Ortega is through seeds. Collect mature seeds from the plant after the end of the growing season, which is around late summer. You can store the seeds in a cool, dry place. Before sowing the seeds, scarify them to improve germination rates, or soak them in water for an entire day.
Sow the seeds in well-drained soil and keep them moist. The ideal temperature for germination is 70 to 75 degrees Fahrenheit. Seeds will germinate in about ten to fourteen days. After the seedlings have developed, you can transplant them into larger pots or an outdoor garden.
Propagation by Vegetative Cuttings
Bidens heterophylla Ortega can also be propagated through vegetative cuttings. Take stem cuttings from healthy plants during the growing season. The cuttings' length should be about 4 to 6 inches, and they should have several leaves. Remove the lower leaves and dip the cuttings in rooting hormone before planting them in a well-draining soil mix.
Place the cuttings in bright, indirect light and keep them damp. You can cover the cuttings with a plastic bag to create a humid environment and facilitate the rooting process. Roots will generally develop in four to six weeks, and the new plant can be transplanted when it has established roots.
