    Dahlias require a consistent watering schedule, aiming to keep the soil moist but not soggy. For the Dahlia 'Witteman's Superba', it's best to water deeply a couple of times a week, providing about one to two gallons per plant each week, depending on weather conditions. Reduce watering frequency to once a week or less during cooler or rainy periods. Always water at the base of the plant to avoid wetting the foliage, which can lead to disease. During peak blooming season, they may need more water, so adjust accordingly.

  • sunLight

    Dahlias thrive in a location with full sun exposure, meaning at least six to eight hours of direct sunlight daily. The Dahlia 'Witteman's Superba' should be planted in a spot where it will receive unfiltered sunlight throughout the day. Partial shade is acceptable, particularly in hot climates, but may reduce blooming.

  • thermometerTemperature

    Dahlias prefer a temperature range between 60°F and 75°F for optimal growth. The Dahlia 'Witteman's Superba' can survive a minimum temperature of about 50°F but should not be exposed to frost conditions. The tubers should be lifted or protected if temperatures drop below this point as cold can damage or kill the plant.

  • scissorsPruning

    Regular pruning encourages Dahlias to produce more blooms and maintain a tidy appearance. For the Dahlia 'Witteman's Superba', deadheading, or removing spent flowers, is crucial to promote continuous blooming throughout the season. Cut back the stems of spent flowers to the next set of leaves. Pruning should be done throughout the blooming season, usually from mid-summer until fall.

  • plantRepotting

  • circleLife cycle

    Dahlia 'Witteman's Superba' begins its cycle in spring when the tuberous roots are planted after the last frost, as the soil warms up. The plant then develops a strong stem and foliage system, with the foliage sprouting from the nodes on the stem in a spiral pattern. Around mid-summer, it starts producing its first flower buds, which will eventually bloom into the characteristic large and vibrant flowers known for Dahlias. After blooming throughout the summer and into early fall, the flowers eventually wilt and the plant prepares for dormancy. With the first frost, the aerial parts of the plant die back, and the tubers must be dug up and stored in a cool, frost-free place over the winter. The stored tubers are then ready to be replanted the following spring, thus repeating the life cycle.

  • sproutPropogation

    • Propogation time


    • The most popular method for propagating Dahlia 'Witteman's Superba', known to many simply as Dahlia, involves the division of tubers. This process should ideally be undertaken in the spring, just as the new growth begins to emerge from the tuber. Gardeners can divide the tubers by using a clean, sharp knife to cut through the tuber ensuring that each division has at least one eye, which is a point on the tuber from which new growth will sprout. Divisions should be allowed to dry for a day or two to form a callous over the cuts, which helps to prevent rot. The divided tubers can then be planted about 4 to 6 inches (10 to 15 centimeters) deep in well-draining soil, with the eye facing upwards, and spaced about 18 to 24 inches (45 to 60 centimeters) apart to provide sufficient room for growth.
