• When and how should I plant my Giant Ball Dahlia tubers?
  Plant the tubers in spring after the danger of frost has passed and the soil has warmed. Choose a sunny spot with well-draining soil. Plant each tuber about 2 inches deep with the “eye” (growing point) facing up. Space them about 24 inches apart to give them room to grow.
• How tall do these dahlias get, and do they need support?
  Giant Ball Dahlias typically grow 3 to 4 feet tall. Thanks to their thick stems, they’re sturdier than most—but staking is still a smart idea, especially in windy areas or once those big blooms start to weigh in. A simple stake or cage will do the trick.
• Will they come back every year?
  In zones 8–10, yes—these dahlias can overwinter in the ground. In colder zones, you’ll need to dig up the tubers after the first frost and store them in a cool, dry place over winter. They’re perennial by nature, but need a little help in chillier climates.
• Can I grow Giant Ball Dahlias in containers?
  Absolutely. Choose a large container (at least 12 inches deep) with good drainage. Container-grown dahlias are great for patios or balconies and give you flexibility to move them for the best sunlight. Just be sure to water regularly—they dry out faster than in-ground plants.
• How long do the flowers last, and when can I cut them?
  You can start harvesting blooms midsummer and enjoy them through fall. For the best vase life—up to 5 days—cut the blooms early in the morning when they're fully open. Use sharp, clean snips and place them straight into cool water.
