Dahlia Dahlia 'Magenta Magenta' (D)

Water

Dahlias, including the 'Magenta Magenta' variety, require a consistent watering schedule to thrive. They should be watered deeply a couple of times a week, more frequently if the weather is particularly hot or dry. Aim to provide about an inch of water per week, which translates to about 0.6 gallons for a small plant or more for larger specimens. The best method is to water at the base of the plant, avoiding the foliage to reduce the risk of disease. During the growing season, ensure the soil remains moist but not waterlogged, as Dahlias do not like to sit in water.

Light

Dahlias thrive in full sun and the 'Magenta Magenta' variant is no exception. It should receive at least 6-8 hours of direct sunlight per day. The best spot for planting is in an area with clear exposure to the sun for the majority of the day without being shaded by trees or structures.

Temperature

Dahlias, such as 'Magenta Magenta,' prefer a temperate climate and do best in temperatures ranging from 60°F to 70°F. Intermediate temperatures in this range are ideal for their growth. Dahlias can survive in temperatures as low as the upper 40s°F for a short period but are not frost-hardy. Prolonged exposure to temperatures above 75°F can stress the plants and affect their blooming.

Pruning

Pruning Dahlias like 'Magenta Magenta' helps to encourage bushier growth and more blooms. Pinch out the growing tips once the plant reaches about 16 inches tall. Throughout the season, deadhead regularly to promote continued flowering. The best time to prune is in the early growing season and as needed to remove dead or damaged tissue.

Cleaning

As needed

Soil

Dahlias prefer a well-draining soil with a pH range of 6.5 to 7.0. Mix equal parts of garden soil, peat moss, and perlite or sand to create the ideal soil for these plants. A nutrient-rich loamy soil with compost incorporated will also support their growth. Regular fertilization during the growing season is recommended.

Repotting

Dahlias should typically be repotted annually. Best repotting time for dahlias is in the spring, after any danger of frost has passed and when new growth begins to emerge. If grown from tubers, dahlias may be repotted when the tubers are planted out.

Humidity & Misting

Dahlias thrive in moderate humidity conditions and do not require excessively high humidity levels. They are adaptable to the humidity found in most outdoor environments where they are typically grown, avoiding overly wet or dry extremes.

Suitable locations

• Indoor

  Ensure bright light, consistent moisture, and good airflow.

• Outdoor

  Plant in sunny spot, provide stakes, water regularly.

• Hardiness zone

Life cycle

The life cycle of the Dahlia 'Magenta Star' begins with seed germination, which requires warm soil and consistent moisture, typically occurring in spring. Following germination, the seedling stage is characterized by the emergence of the cotyledons and the first set of true leaves. As the plant enters the vegetative stage, it develops a robust stem structure and a lush foliage canopy, which prepares it for the flowering stage. Flowering occurs in late summer to fall, where the 'Magenta Star' showcases its vibrant, magenta-colored blooms that attract pollinators. After pollination, the plant may produce seeds if conditions are right, or more commonly tubers are developed, which can be overwintered underground or stored for replanting the following season. Finally, as temperatures drop in winter, the plant enters dormancy, with above-ground growth dying back, and the lifecycle can begin anew from the tubers the following spring.

Propogation

  Spring-Early Summer

• The most popular method of propagation for the Dahlia 'Magenta Star' is by dividing tubers. This process typically takes place in the spring, after the last frost when the soil has warmed up sufficiently. Gardeners will dig up the tuberous roots of the plant, which have been overwintered in a frost-free location, and carefully divide the clump ensuring that each division has at least one eye or growing point. Divisions should then be planted directly into the ground, with the top of the tuber being just below the surface, approximately an inch or two deep (2.5 to 5 centimeters). Soil should be well-draining and the tubers should be spaced approximately 18 to 24 inches apart (45 to 60 centimeters) to allow adequate room for growth. It's crucial to maintain consistent moisture after planting until new growth appears, indicating that the tuber has successfully established.
