Tickseed-sunflower thrives in full sun, requiring at least 6 hours of direct sunlight daily. It exhibits excellent heat tolerance, making it suitable for hot climates. Tickseed-sunflower can withstand cold temperatures down to USDA Zone 4, but may benefit from mulching in colder regions. It prefers an optimum temperature range between 65-75°F (18-24°C). During summer, ensure adequate watering to prevent wilting. In winter, protect from frost by covering with a frost cloth. Place Tickseed-sunflower in well-draining soil to avoid waterlogging. It is a sun-loving plant, so ensure it receives ample sunlight throughout the day. Avoid shading from nearby structures or trees. Tickseed-sunflower's strength lies in its ability to thrive in bright, direct sunlight.

What is Tickseed-sunflower (Bidens aristosa)?
What is Tickseed-sunflower (Bidens aristosa)
Flower meaning
Tickseed-sunflower thrives in well-drained soil with a pH level between 6.0 and 7.0. It requires a balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium. Fertilizer should be applied in early spring before new growth begins and again in mid-summer to support blooming. A slow-release fertilizer is recommended to prevent nutrient leaching. The amount of fertilizer applied should follow the manufacturer's instructions based on the size and age of the plant. Regular soil testing is essential to monitor nutrient levels and adjust fertilizer applications accordingly. High-quality soil rich in organic matter promotes healthy growth and flowering in Tickseed-sunflower.
Calendar of Tickseed-sunflower (Bidens aristosa)
Calendar
Tickseed-sunflower, also known as "Coreopsis," symbolizes cheerfulness, joy, and happiness in the language of flowers commonly used in America. For example, gifting Tickseed-sunflowers conveys a message of positivity and brightening someone's day. This flower language is often associated with warm feelings and spreading smiles.

How to grow Tickseed-sunflower (Bidens aristosa)
Watering
Tickseed-sunflower benefits from pruning to maintain its shape, encourage new growth, and improve flowering. Pruning is necessary to remove dead or damaged branches, enhance air circulation, and prevent disease. The best time to prune Tickseed-sunflower is in early spring before new growth appears. When pruning, use clean, sharp tools to make precise cuts just above a leaf node or lateral branch. After pruning, remove any debris from around the plant to prevent the spread of pests and diseases. Additionally, water the plant thoroughly to help it recover from the pruning stress. Regular pruning will help Tickseed-sunflower thrive and remain healthy.
Soil and Fertilizer
Tickseed-sunflower can be propagated through seeds, division, and cuttings. Seeds are sown in well-draining soil, kept moist until germination. Division involves separating the plant into sections with roots for replanting. Cuttings are taken from healthy stems, rooted in a growing medium. Leaf cuttings can also be used by planting healthy leaves in soil or water until roots develop. To ensure successful propagation, it is recommended to use a combination of methods to increase the chances of success and produce more plants.
Sunlight and Place
Tickseed-sunflower thrives best when potted rather than planted in-ground. To pot Tickseed-sunflower, choose a container with drainage holes, fill it with well-draining soil, and plant the seedling at the same depth as it was in its nursery pot. Water thoroughly after planting, keeping the soil consistently moist but not waterlogged. When repotting, select a slightly larger pot to accommodate growth, gently loosen the roots, and place the plant in the new container. Ensure the plant is centered and add fresh soil around it. Mist the plant after repotting to reduce transplant shock. If mishowing occurs, check for pests, adjust watering, and provide adequate sunlight.
Advanced Information of Tickseed-sunflower (Bidens aristosa)
Pruning
Tickseed-sunflower is susceptible to various pests and diseases, including aphids, spider mites, powdery mildew, and rust. These pests and diseases can weaken the plant, causing wilting and stunted growth. Aphids and spider mites feed on the plant sap, leading to yellowing of leaves and distorted growth. Regularly inspecting the plant for these pests and using insecticidal soap can help prevent infestations. Powdery mildew appears as a white powdery substance on leaves, affecting photosynthesis. To prevent powdery mildew, ensure good air circulation around the plant and avoid overhead watering. Rust is characterized by orange or yellow spots on leaves, causing them to wither and die prematurely. Removing infected leaves and avoiding overhead watering can help control rust.
Planting and Harvest
Tickseed-sunflower typically blooms from late spring to early fall in the United States. The flowers are at their peak in midsummer, usually in July and August. Blooming occurs once a year, lasting for several weeks. It takes about 2 to 3 weeks for the flowers to fully bloom. To extend the blooming period, deadhead spent flowers regularly and provide adequate sunlight and well-drained soil. Maintaining consistent moisture levels can also help prolong the flowering time. Tickseed-sunflowers are known for their vibrant colors and are attractive to pollinators like bees and butterflies. They are a popular choice for garden borders and landscaping due to their long-lasting blooms.
Propagation
Tickseed-sunflower offers various varieties such as 'Goldilocks', 'Moonshine', and 'Zagreb'. 'Goldilocks' features golden-yellow petals with a compact growth habit. 'Moonshine' displays pale yellow flowers atop tall stems. 'Zagreb' showcases bright yellow blooms and finely cut foliage. When selecting seeds, opt for plump, firm ones without signs of damage. For seedlings, choose those with healthy green leaves and sturdy stems. Ensure the roots are well-developed and not root-bound. It is essential to select varieties and seeds that suit your garden's sunlight and soil conditions for optimal growth.
Pests and Diseases
Tickseed-sunflower, scientifically known as Bidens aristosa, is a perennial plant native to North America. It belongs to the Asteraceae family and is characterized by its slender stems, toothed leaves, and yellow daisy-like flowers. The flowers typically bloom in late summer to fall, attracting pollinators like bees and butterflies. Bidens aristosa is commonly found in wetlands, meadows, and along stream banks. The plant can reach a height of 3 to 6 feet and produces small, dark fruits with barbed awns that aid in seed dispersal. Its name "Bidens" is derived from the Latin word "bi" meaning two and "dens" meaning tooth, referring to the two-pronged awns on its seeds. This plant is relatively easy to grow in moist, well-drained soil and full sun to partial shade. It is often used in native plant gardens and natural landscaping due to its attractive flowers and wildlife benefits.

Q&A of Tickseed-sunflower (Bidens aristosa)
- Is there a recommended way to choose Tickseed-sunflower?
Tickseed-sunflowers require watering once a week during the growing season. In the spring and summer, water deeply until the top 1-2 inches of soil are moist. During the fall and winter, reduce watering frequency to once every two weeks. Ensure the soil dries out slightly between waterings to prevent root rot. Adjust watering based on soil humidity levels and weather conditions. Avoid overwatering as it can lead to fungal diseases. Use a watering can or drip irrigation to deliver water directly to the base of the plant. Monitor the plant's response to watering to fine-tune the schedule.
