Bidens
Bidens, also known as tickseed or beggarticks, is a genus of flowering plants that belong to the Asteraceae family. These plants are native to North and South America and are widely cultivated for their vibrant yellow flowers and delicate foliage.
Bidens thrive in full sun. They require at least 6-8 hours of direct sunlight per day to produce abundant blooms. Bidens are warm-season plants and prefer temperatures between 60°F and 80°F (15°C - 27°C). They are not frost-tolerant, so it's important to protect them from cold temperatures.
Bidens prefer well-draining soil with a pH level between 6.0 and 7.0. Before planting, it's recommended to amend the soil with organic matter to improve drainage and fertility. Bidens have moderate water needs. It's important to keep the soil evenly moist, but not waterlogged, as excessive moisture can lead to root rot.
Applying a balanced, slow-release fertilizer once a month during the growing season can help promote healthy growth and abundant blooms. Look for a fertilizer with an NPK ratio of 10-10-10 or 14-14-14, which provides a balanced mix of nitrogen, phosphorus, and potassium.
Regular pruning and deadheading are essential for maintaining the shape and prolonging the blooming period of Bidens. Deadheading, which involves removing spent flowers, encourages the plant to produce more blooms. Additionally, pruning helps to control the size and shape of the plant, preventing it from becoming leggy or overgrown.
While bidens are generally resistant to pests and diseases, they can occasionally be affected by aphids, spider mites, or powdery mildew. To prevent infestations, regularly inspect your plants and take prompt action if any signs of pests or diseases are detected. In some cases, using organic insecticidal soap or neem oil can help control pests.
