  • water dropWater

    Dahlias require regular watering, especially during dry periods. For the Dahlia 'Twyning's Chocolate', water thoroughly once or twice a week, providing about 1-2 inches of water each time. During hot, dry weather, you may need to water more frequently. Avoid overhead watering to prevent fungal diseases, and aim for the base of the plant to keep the foliage dry. Ideally, water in the morning so that any water that gets on the foliage will have time to dry before nightfall. Overwatering or allowing the plant to sit in water can lead to root rot, so ensure good drainage.

  • sunLight

    Dahlias thrive in full sunlight, and the 'Twyning's Chocolate' Dahlia is no exception. Place it in a spot where it will receive at least six to eight hours of direct sunlight daily. Some afternoon shade can be beneficial in extremely hot climates to prevent scorching. Avoid heavily shaded areas, as insufficient light can lead to poor flowering and weak growth.

  • thermometerTemperature

    Dahlias, including the 'Twyning's Chocolate', grow best in temperatures between 60°F and 75°F. They can survive minimum night temperatures of around 50°F but should be protected if temperatures are expected to drop lower to avoid damage. Dahlias are not frost-tolerant; exposure to temperatures below 32°F will damage or kill the plant. In climates with cold winters, the tubers need to be lifted from the ground and stored in a frost-free place.

  • scissorsPruning

    Prune 'Twyning's Chocolate' Dahlias during the growing season to encourage bushier growth and more blooms. Pinch out the tips of the main shoot down to the 3rd or 4th pair of leaves when the plant is about 12 inches tall to promote branching. Throughout the season, remove any dead or damaged stems and spent flowers (deadheading) to encourage continued blooming. The best time for pruning is late spring through summer, as the plant begins to grow and produces buds.

  • circleLife cycle

    The life of a Dahlia 'Twyning's Chocolate', also known as Chocolate Dahlia, begins when the tuber is planted in well-draining soil after the last frost of spring. The plant emerges from dormancy and starts vegetative growth, developing a stout stem and leaves. During the growing season, the Chocolate Dahlia will produce distinctive burgundy-black foliage and flower stalks, leading to its unique creamy-white flowers with dark red flecks starting in early summer. This blooming period can last until the first frost of fall, during which flowers can be deadheaded to encourage further blooming. As temperatures drop, the Chocolate Dahlia enters senescence, and the aerial parts die back, signaling the time to dig up and store the tubers for winter if the climate is prone to freezing. The next growing season begins when these tubers are replanted, thus repeating the plant's life cycle.

      Spring-Early Summer

    • The most popular method of propagating Dahlia 'Twyning's Chocolate', also known simply as dahlia, is through division of tubers. This is typically done in the spring, just before the growing season starts when the tubers begin to sprout and you can clearly see the eyes or growth points. The clump of tubers should be carefully lifted from the ground and any excess soil gently shaken off. Using a sharp, clean knife, the tuber clump is divided so that each division contains at least one eye, along with a good amount of tuber attached to sustain the plant. It's essential to make clean cuts to minimize the risk of disease. After cutting, the divisions can be planted directly into the garden or potted up, placed in a sunny location, and kept moist until the new dahlia plants begin to grow vigorously. It's important to ensure that the soil temperature is around 60°F (15.5°C) for optimal growth.
