As needed
  • water dropWater

    Dahlias require a consistent watering schedule, and 'Ragged Robin' is no exception. They should be watered deeply two to three times per week, depending on weather conditions, to encourage deep root growth. Each watering session should provide the equivalent of approximately 1 inch of rainfall; this translates to about 0.6 gallons per square foot. During particularly hot or dry spells, increase the frequency to ensure the soil remains moist but not waterlogged. It's best to water early in the morning to reduce evaporation and help prevent fungal diseases.

  • sunLight

    Dahlias thrive in full sunlight and 'Ragged Robin' benefits from at least 6 to 8 hours of direct sunlight daily. The ideal location would be in an area that receives morning sun and is protected from the harsh afternoon sun, which can sometimes be too intense, especially in hotter climates. Avoid planting in areas that are shaded for a significant portion of the day, as this will hinder flowering.

  • thermometerTemperature

    'Ragged Robin' dahlias prefer warm conditions with temperatures ranging from 60 to 75 degrees Fahrenheit for optimal growth. They can survive in temperatures as low as 50 degrees Fahrenheit but won't thrive if temperatures dip below this. It's crucial to ensure that the plants are not exposed to frost, as dahlias are sensitive to cold and cannot withstand freezing conditions.

  • scissorsPruning

    Pruning 'Ragged Robin' dahlias is essential for maintaining strong stems and promoting prolific blooming. Pinch out the tips of the main shoots when they are about 12 inches tall to encourage bushier plants. Throughout the blooming season, regularly deadhead spent flowers to stimulate continuous blooms. The best time for major pruning and cutting back is just before the first frost when the foliage begins to yellow.

  • bambooSoil

    Dahlias prefer well-draining soil rich in organic matter with a slightly acidic to neutral pH between 6.5 and 7.0. A good soil mix for Dahlias like 'Ragged Robin' includes two parts loam, one part peat moss, and one part sand to ensure proper drainage and fertility.

  • plantRepotting

    Dahlias, including 'Ragged Robin', usually don’t need repotting as they are not grown as long-term potted plants. Instead, lift and store tubers annually after the first frost if you are in a colder zone, and replant them after the last frost in spring.

  • circleLife cycle

    Dahlia 'Ragged Robin' begins its life as a tuber, which is planted in the ground after the risk of frost has passed. The tuber sprouts and develops a strong stem and leafy growth, drawing nutrients and energy from the soil and sunlight. As the plant matures, it starts to form buds, which eventually bloom into the distinctive ragged, colorful flowers that dahlias are known for. After the flowering stage, which can last through summer and into fall, the plant sets seeds, although many gardeners propagate dahlias vegetatively through their tubers. As temperatures drop towards winter, the aerial parts of the plant die back, and the tuber enters a dormant phase. Before the frost, gardeners typically dig up the tubers and store them in a cool, dry place over winter, to be replanted the following spring, thus repeating the life cycle.

      Spring-Early Summer

    • The popular method for propagating the Dahlia 'Ragged Robin' is by dividing its tubers. This should be done in the spring when the soil has warmed up and the tubers start to sprout, guaranteeing that the pieces have a chance to grow when planted. Carefully lift the clump of tubers from the ground using a spade or fork. Gently brush off any excess soil and use a sharp knife to cut through the tubers, ensuring that each division has at least one eye or shoot. Divisions should be allowed to dry for a few days to form a callus over the cut areas, which helps to prevent rot. Once callused, the tuber sections can be planted about 6 to 8 inches (15 to 20 centimeters) deep and spaced about 18 to 24 inches (45 to 60 centimeters) apart in well-draining soil and in a location that receives full sun for robust growth.
