  • water dropWater

    Dahlias require a consistent watering schedule. Typically, water once or twice a week, applying approximately one gallon per plant each time, depending on weather conditions. Ensure the soil around your Dahlia is kept moist but not waterlogged. During peak bloom time or particularly hot days, you may need to water more frequently. Cut back on watering as the plant goes dormant in the fall.

  • sunLight

    Dahlias thrive in a spot that receives full sun, which is defined as at least 6 to 8 hours of direct sunlight daily. Place your Dahlia 'Westerton Lilian' in an area where it will receive unfiltered morning light followed by some partial shade during the hottest part of the afternoon if you're in a particularly hot climate.

  • thermometerTemperature

    Dahlias prefer a growing environment where the temperature is between 60 to 70 degrees Fahrenheit during the day. They can survive in temperatures down to 50 degrees Fahrenheit at night, but they will not thrive in temperatures below that. Gardeners should also ensure that Dahlias are not exposed to frost, as temperatures below freezing can damage or kill the plant.

  • scissorsPruning

    Pruning dahlias helps encourage bushier growth and more blooms. Deadheading, or removing spent flowers, should be done regularly throughout the blooming season. Cut back the stems to about 1/4 inch above a set of leaves. For larger blooms, pinch back the side shoots as the plant grows. The best time for major pruning is early spring.

  • plantRepotting

    Dahlias, including the 'Westerton Lilian', do not need to be repotted frequently. They are typically replanted annually from tubers after the last frost in spring. However, if growing in containers, consider repotting every year with fresh soil to replenish nutrients.

  • circleLife cycle

    Dahlia 'Westerton Lilian' begins its life cycle as a tuber planted in the ground after the last frost has passed, usually in spring. The tuber sprouts and a stem emerges, developing leaves and eventually forming flower buds. As summer progresses, the plant blossoms, showing off its vibrant flowers which may attract pollinators such as bees and butterflies. After blooming, the flowers fade and the plant channels its energy into the growth and storage of nutrients back into the tubers. As temperatures drop in the fall, the aerial parts of the plant start to wither, and it enters dormancy through the winter months. To complete the cycle, the tubers can be left in the ground or dug up, stored, and replanted the following spring to start the process anew.

    • Propogation time

      Spring-Early Summer

    • The Dahlia 'Westerton Lilian', commonly known as a type of garden dahlia, is effectively propagated through division of tubers. The appropriate time to propagate dahlias through division is in the spring after the danger of frost has passed and when the sprouts begin to emerge from the tubers. This typically occurs when the soil has warmed to about 60°F (15.5°C). To propagate by division, carefully lift the dahlia clump from the ground with a spade, ensuring not to damage the tubers. Wash away the soil gently to reveal the natural dividing lines between the tubers. Each division should include at least one eye or bud from which the new stem will grow. Use a clean, sharp knife to cut the tubers apart, and allow the cut surfaces to dry for a few days to form a callus over the wound. Once the cut has healed, the tuber divisions can be planted in well-draining soil with the eyes facing upwards, buried about 4 to 6 inches (10 to 15 cm) deep.
