  • circleLife cycle

    Dahlias, including the 'John Street' variety, begin their life cycle when their tubers are planted in the ground after the last frost, usually in spring. They undergo vegetative growth, developing a strong root system and foliage as the soil temperature rises. Flower buds emerge following the foliage development, leading to flowering in late summer to early fall, showcasing their vibrant blooms. As the plant matures, the blooms eventually fade and the plant enters a period of dormancy with the onset of cooler temperatures in fall. During dormancy, the tubers can be lifted from the ground and stored in a cool, dry place to overwinter. The following spring, the tubers can be replanted, completing the cycle and beginning a new growth season.

      Spring-Early Summer

    • The Dahlia 'John Street' (Waterlily type) is best propagated through division, a process typically carried out in spring just before the new growth begins. To propagate by division, carefully lift the tuber clump from the ground after the plant has died back, usually after the first light frost. Gently clean the soil off of the tubers and proceed to cut them into separate clumps, ensuring each division has at least one eye, which is a bud from which the new plant will grow. The divisions should be made using a sharp, sterile knife to minimize damage and reduce the risk of disease. After cutting, it can be beneficial to let the cut surfaces dry and callous over for a day before planting. The divisions are then planted in well-draining soil at a depth approximately three times the height of the tuber, which is usually between 2 to 4 inches (5 to 10 centimeters). Water lightly just to moisten the soil and avoid watering again until you notice new growth to prevent rot.
