Fleurel® Dahlias

How to Plant and Care for dahlias

When to Plant

• Wait until all danger of frost has passed and soil is at least 60°F.
• Store tubers in a cool, dark, dry place until ready. Do not refrigerate.

Planting Dahlia Tubers in the Ground

• Choose a full sun location with well-drained soil.
• Dig a hole at least 2" deep and wide enough for the tuber or clump.
• Place tuber with the eyes or cut stem facing up (or lay on its side if unsure).
• Cover with soil. Do not water immediately unless soil is dry.

Planting in Containers

• Use a large container (minimum 12" deep) with drainage holes.
• Fill with high-quality potting mix. Plant tuber as above.
• Place in full sun and water only when the soil dries out.

Ongoing Care

• Water deeply 2–3 times per week once growth appears; keep soil evenly moist.
• Mulch to retain moisture and reduce weeds.
• Support with stakes as plants grow to prevent flopping.
• Fertilize monthly with a low-nitrogen fertilizer (5-10-10 or similar).
• Deadhead spent blooms to encourage more flowers.

In Zones 7 and colder, dig up tubers after first frost and store indoors for next year.

Fleurel® Dahlia FAQs

• 1. How big do Fleurel Dahlias get, and where should I plant them?
  Fleurel Dahlias grow to about 3 to 4 feet tall, with blooms up to 8 inches across—think dinner-plate size! Plant them in full sun with well-drained soil. They're stunning in garden beds, borders, or containers where they’ll get at least 6 hours of sun daily.
• 2. Can Fleurel Dahlias grow in pots or containers?
  Yes, and they look incredible doing it! Choose a large container (at least 12–16" wide and deep) with good drainage. Container-grown Fleurels let you spotlight those huge white blooms on patios, balconies, or near entryways for maximum visual impact.
• 3. How do I care for Fleurel Dahlias once they start growing?
  Stake them early to support those heavy blooms, and keep the soil evenly moist (but not soggy). Deadhead spent flowers to encourage more blooms. Feed monthly with a low-nitrogen fertilizer for best flowering.
• 4. Are Fleurel Dahlias good for cut flower arrangements?
  Absolutely—they're a florist favorite! With long, sturdy stems and blooms that last up to a week in a vase, Fleurels make elegant centerpieces or bridal-worthy bouquets. Cut in the morning once blooms are fully open for the best vase life.
• 5. Do Fleurel Dahlias need to be dug up in winter?
  Yes, in zones colder than USDA Zone 8, you'll need to lift the tubers after the first frost. Let them dry, then store in a cool, frost-free spot over winter. In warmer zones, you can mulch heavily and leave them in the ground.
