Dahlia is a genus of flowering plants that belong to the Asteraceae family. This group of plants has around 42 species that can vary in size, shape, and color. Dahlias are native to Central America, but they can be found growing all over the world. Dahlias can grow up to six feet tall.
Caring for Dahlia
When planting Dahlias, choose a sunny location with well-draining soil. Make sure to provide support for taller varieties to prevent them from flopping over as they grow. Regular watering is crucial during the growing season, particularly during hot and dry periods, as dahlias require lots of water. Applying mulch around the base of the plants can help retain soil moisture and suppress weed growth.
Deadheading spent flowers encourages continuous blooming and redirects the plant’s energy toward producing new blooms. Additionally, disbudding and removing extra side buds can result in larger and more impressive individual flowers. Dahlias are also susceptible to pests like aphids and slugs, so monitoring for signs of infestation and taking appropriate measures is essential for care.
Leaves and Flowers
The leaves of the Dahlia plant are dark green and can grow up to six inches long. They typically have large flowers which can range in size from two inches to twelve inches in diameter. The flowers can be single or double, with a variety of shapes, including pom-pom, cactus, and waterlily. Dahlia plants come in bright colors and they can also have multicolored petals.
