Bidens can grow in partial sun conditions, but for the biggest and best blooms, full sun is preferred. Any location you choose to plant Bidens should receive at least 4 hours of direct sunlight per day. Without adequate light, the plant will still grow but may not produce as many blooms and is likely to be leggier.
Whether you’re planting Bidens in an outdoor garden or a container, ensure that they have well-drained soil to avoid problems with root rot. Also, this abundantly blooming plant thrives in rich, humus soil. It can tolerate a variety of pH levels in soil but is generally considered to do best in neutral to slightly acidic soil types.
These plants are not frost-resistant and will die under 40 degrees Fahrenheit. In climates that keep above this threshold, the plant will return year after year as a perennial. Otherwise, it will need to be re-planted as an annual each year.
These plants are considered fairly drought-resistant. However, they do require regular watering for their best appearance and longevity. An inch of water per week is typically sufficient. Water before wilting begins.
To flourish, the abundantly flowering Bidens plant will require nutrient-rich soil. How much fertilizer to use and what type is generally specified by the specific type of Bidens plant you’re growing. It’s generally recommended to supplement this plant with a general-purpose fertilizer or to use a timed-release fertilizer when planting. Fertilizer is especially important if you are growing Bidens in a container.
Bidens are easy to maintain and don’t need to be pruned or deadheaded. However, in favorable growing conditions, you might choose to prune the plant back if it becomes too large.
Good job! You are taking good care of your Bidens.
Scout and monitor for insects, including whiteflies, aphids, and thrips. If these pests appear, deal with them with a spray of insecticidal soap. Diseases to watch for include botrytis and pythium. Drench with broad-spectrum fungicides as a preventative measure.

Sreten null
Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
