Tuber Pack Options:  Available in packs of 1, 5, 10, or 20 tubers

Planting Tubers

Dahlias typically take 90 to 120 days from planting to fully bloom, depending on the variety and growing conditions. After planting tubers in spring (after the last frost), you can expect to see the first flowers by mid to late summer, with continuous blooms lasting until the first fall frost. Proper sunlight, well-drained soil, and regular watering help ensure healthy growth and vibrant flowers.

Climate Zones

Dahlia tubers should be stored in a cool place (DO NOT FREEZE) and planted in the spring after the last frost when the soil has warmed to at least 60°F (16°C). Here’s a general guide based on USDA hardiness zones:

When to Plant Dahlia Tubers by Climate Zone

• Zone 3-5 (Cold Climates) → Late May - Early June
  Start tubers indoors 4-6 weeks before the last frost and transplant when the soil warms up.

• Zone 6-7 (Moderate Climates) → Mid to Late April
  Plant tubers once the risk of frost has passed and the soil is warm.

• Zone 8-9 (Mild Climates) → March - Early April
  Plant directly in the ground after the last frost or start earlier in containers.

• Zone 10-11 (Warm Climates) → Late February - Early March
  Dahlias can be planted earlier, but they may struggle with extreme summer heat—provide afternoon shade if needed.

For colder zones (3-7), tubers must be dug up and stored before the first frost in fall, while in warmer zones (8-11), they can often be left in the ground year-round with proper mulching.

Growing Guidance

To grow healthy and vibrant dahlias, they need:

1. Full Sun – At least 6-8 hours of direct sunlight per day.
2. Well-Drained Soil – Loose, fertile soil with good drainage; slightly acidic to neutral (pH 6.5-7.0) is ideal.
3. Proper Spacing – 12-24 inches apart, depending on the variety, for good air circulation.
4. Regular Watering – Deep watering 2-3 times per week, keeping soil moist but not soggy.
5. Support for Tall Varieties – Staking or caging taller dahlias to prevent them from falling over.
6. Balanced Fertilization – Low-nitrogen fertilizer (5-10-10 or 10-20-20) every few weeks for strong blooms.
7. Pinching & Deadheading – Pinch young plants for bushier growth and remove spent flowers to encourage continuous blooming.
8. Pest & Disease Control – Watch for aphids, slugs, and powdery mildew; use organic or chemical treatments as needed.
9. Frost Protection – Lift and store tubers in cold climates before the first frost for next season’s planting.
