    Dahlia Tubers (Decorative) - Yellow Jill 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 decorative dahlia?

    Decorative dahlias feature fully double blooms with broad, relatively flat petals that overlap in lush layers, completely concealing the flower's center. Their blooms range from small to dinnerplate-sized, making them a popular choice.

    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.

    Can I plant Yellow Jill Dahlia alongside other dahlia varieties?

    Absolutely. Combining decorative dahlias with ball, cactus, or collarette varieties creates an interesting mix of flower shapes and textures. Allow approximately 18 to 24 inches between plants to promote healthy growth and good air circulation.

    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.
