How to Plant and Care for Bidens
A Guide to Growing Bidens Ferulifolia
Bidens ferulifolia, commonly known as Goldmarie or Zweizahn, is a popular flowering plant that adds vibrant colors and attracts pollinators to your garden. This easy-to-grow plant offers a profusion of daisy-like blooms in shades of yellow, orange, and red, creating a cheerful and lively display throughout the summer months.
Choosing the Right Bidens Variety
There are numerous varieties of Bidens, each with its own unique characteristics. Some of the most commonly grown varieties include:
- 'Sun Drop': A bushy plant with bright yellow blooms that reach up to 2 inches in diameter
- 'Golden Pom-Pom': A compact variety with large, golden-yellow pom-pom-like flowers
- 'Orange Sunshine': A vigorous plant with a profusion of orange-yellow blooms
- 'Red Planet': A unique variety with deep red flowers that resemble daisies
- 'Cupcake Pink': A charming variety with soft pink blooms that resemble miniature cupcakes
Planting and Care Tips
Bidens prefers full sun to partial shade and well-drained soil. It is important to choose a planting location that receives at least 6 hours of sunlight per day. When planting, space the plants 12-18 inches apart to allow for proper growth and air circulation.
Water the plants regularly, especially during hot and dry weather. Avoid overwatering, as this can lead to root rot. Fertilize the plants every few weeks with a balanced liquid fertilizer to promote healthy growth and flowering.
Bidens is a relatively low-maintenance plant, but it may benefit from occasional pruning to remove spent flowers and encourage new growth. Regular pruning also helps to maintain a compact and bushy shape.
Overwintering Bidens
Bidens ferulifolia is not winter hardy in most climates and will need to be overwintered indoors if you want to preserve it for the following season. Dig up the plants in the fall and transplant them into pots filled with fresh potting soil. Place the pots in a bright spot with temperatures between 50 and 60 degrees Fahrenheit.
Water the plants sparingly over the winter months and fertilize them once a month with a diluted liquid fertilizer. In the spring, when temperatures warm up and the threat of frost has passed, gradually introduce the plants to outdoor conditions before transplanting them back into the garden.
