  • water dropWater

    Dahlias require a consistent watering schedule to maintain moist but not soggy soil, especially during the growing season. Generally, Dahlias should be watered two to three times a week, with adjustments made for rainfall and temperature. A good method is to provide a deep watering which encourages the roots to grow deeper into the ground; this translates roughly to about 1-2 gallons per plant each time, depending on the soil type and weather conditions. This could sum up to around 2-6 gallons per week. It's important to water at the base of the plant to keep the foliage dry and prevent fungal diseases.

  • sunLight

    Dahlias thrive in a location where they can receive full sun, which means at least 6-8 hours of direct sunlight daily. An ideal spot for Dahlias is in a garden bed that is exposed to the morning sun but has some protection from the intense afternoon heat, particularly in hotter climates. These plants bloom best with plenty of light, so avoid planting in shaded areas that could hinder their growth.

  • thermometerTemperature

    Dahlias grow best in temperatures ranging from 60°F to 70°F and require a frost-free period to thrive. They can tolerate a minimum temperature of about 50°F and a maximum of 90°F, but prolonged exposure outside this range can be detrimental. Ideally, Dahlias should be planted when the danger of spring frost has passed and dug up after the first fall frost, if in a region with harsh winters.

  • scissorsPruning

    Regular pruning, also known as deadheading, is necessary for Dahlias to encourage continuous flowering throughout the season. Cut off spent flowers and any broken or damaged stems to redirect the plant's energy into producing new blooms. The best time to prune is late winter or early spring before new growth begins. Dahlias should also be cut back before overwintering or after the first killing frost if they are lifted from the ground.

    Dahlias prefer well-draining, fertile soil with a pH ranging from 6.5 to 7.0. A mix of garden soil, compost, and perlite or sand is beneficial for Dahlia 'Carol Klein' to ensure proper drainage and aeration. Regular incorporation of organic matter will also support vibrant blooms and healthy growth.

  • plantRepotting

    Dahlias, including Dahlia 'Carol Klein', generally don't need repotting as they are typically grown as annuals in most climates. Instead, the tubers are lifted after the first frost in the fall, stored during the winter, and replanted in the spring.

  • circleLife cycle

    The life cycle of the Dahlia 'Carol Klein' (Dahlia x hybrida) begins with a dormant tuberous root, which sprouts in spring when soil temperatures rise and daylight increases. It grows rapidly, producing a sturdy stem and lush foliage as it enters the vegetative stage. Flower buds develop in early summer and, when conditions are favorable, blossom into the plant's striking flowers by mid to late summer. The plant continues to bloom prolifically until the first frost, which marks the end of its active growth period. After flowering, the Dahlia 'Carol Klein' begins to wilt and retreat into dormancy; it's then that the tubers can be dug up, stored over winter, and replanted the following spring, completing the cycle. This perennial plant relies on the careful overwintering of its tubers to survive year after year, providing a continual seasonal display of blooms.

      Spring-Early Summer

    • Dahlia 'Carol Klein', commonly known as simply Dahlia, is most commonly propagated through division, which is typically done in the spring just before new growth begins. To propagate by division, you should carefully lift the tuberous root clumps from the ground after the foliage has died back and the soil is dry. Using a sharp, clean knife, divide the clump so that each division has at least one eye, the point from which the new growth emerges. These divisions should be planted about 4-6 inches (10-15 cm) deep in well-draining soil, spaced about 18-24 inches (45-60 cm) apart, allowing for adequate growth space. Ensure that the eyes are facing upwards when planting. It's crucial to water the divisions evenly to encourage growth but avoid waterlogging, as this can cause the tubers to rot.
