Dahlia Collarette Growing Guide

Dahlia collarette flowers are a type of dahlia known for their distinctive appearance and intricate, layered petals. They are a member of the Asteraceae family and are native to Central and South America, although they are now widely cultivated and appreciated all over the world.

Collarette dahlias are characterized by a single row of larger petals surrounding a central disc of smaller petals, giving them a unique and eye-catching appearance. They typically grow to a height of 2 to 4 feet and produce flowers that can be up to 6 inches in diameter. The flowers come in a wide range of colours, including red, pink, orange, yellow, white, and bi-colours, and are popular for use in cut flower arrangements and as a colourful addition to garden beds and borders.

Collarette dahlias are fairly easy to grow, but they do require well-draining soil and regular watering to thrive. They are generally planted in the spring and bloom in late summer or early fall, depending on the climate. With their unique and eye-catching appearance, collarette dahlias are a popular choice for gardeners and florists alike.

Growing Dahlia collarette flowers is relatively easy, but it requires a bit of planning and attention to detail. Here are some steps to help you grow these beautiful flowers:

  1. Choose a sunny location: Dahlias need full sun to grow and thrive. Choose a spot in your garden that receives at least 6-8 hours of direct sunlight per day.
  2. Prepare the soil: Dahlias prefer well-drained soil that is rich in organic matter. Before planting, work some compost or well-rotted manure into the soil to improve its fertility and structure.
  3. Plant the tubers: Dahlia tubers should be planted in the spring, after the last frost has passed. Dig a hole that is about 6-8 inches deep and place the tuber in the hole with the concave side facing up. Cover the tuber with soil, and water it well.
  4. Water and fertilize: Dahlias need regular watering to keep their soil moist but not waterlogged. Water deeply once a week, or more often during dry spells. Fertilize every 3-4 weeks with a balanced fertilizer, such as a 10-10-10 formula.
  5. Support the plants: Collarette dahlias can grow quite tall, so they may need support to prevent them from falling over in strong winds or heavy rain. Stake the plants or use cages to keep them upright.
  6. Deadhead regularly: To encourage continued blooming, remove spent flowers regularly. This will also help prevent disease and keep the plants looking tidy.
  7. Dig up the tubers: In colder climates, Dahlia tubers need to be dug up in the fall and stored indoors for the winter. Allow the foliage to die back naturally, then dig up the tubers, clean them off, and store them in a cool, dry place until spring.
