Learn about Dinnerplate Dahlia seed germination, flower size, and growing requirements.
Dinnerplate dahlias can be grown from seeds, but seedlings may vary in flower color, size, and form. Named cultivars are generally propagated from tubers or cuttings to preserve their characteristics. Check the seed packet for the expected variety and flower traits.
Choose a suitable large-flowered variety, provide full sun, fertile well-drained soil, consistent moisture, and appropriate spacing. Some large-flowered dahlias benefit from removing side buds so more energy goes into selected blooms. Flower size also depends on the genetics of the plant grown from seed.
Start Dinnerplate Dahlia Seeds indoors several weeks before the last expected frost. Transplant seedlings outdoors after frost danger has passed and the soil has warmed. In regions with long, warm growing seasons, outdoor sowing may also be possible under suitable conditions.
