    Dahlia Tubers (Waterlily) - R Mona FAQs

    When do I plant dahlia tubers?

    Think of planting your dahlias when you plant your tomatoes. Plant in spring after the danger of frost has passed and the soil has warmed to at least 60°F. In warmer climates, planting can begin earlier than in regions with colder springs.

    What is a waterlily dahlia?

    Waterlily dahlias have fully double blooms with broad, gently cupped petals arranged in a relatively flat, symmetrical shape. Their elegant appearance resembles a waterlily floating on water, giving Blue Wish its graceful flower form.

    Do dahlias need staking?

    Staking is recommended, particularly in windy locations or when plants become heavily loaded with flowers. Providing support early helps protect stems as the plant grows.

    How can I prevent powdery mildew on R Mona Dahlia?

    Provide adequate spacing and good air circulation, avoid overcrowding, and water at the soil level rather than wetting the foliage. Remove affected leaves promptly and keep the planting area free of fallen plant debris.

    Will dahlias come back every year?

    Dahlias are tender perennials that can overwinter in the ground in sufficiently warm climates with good drainage. In colder regions, tubers should be lifted after frost and stored in a cool, frost-free location until spring.
