For the past ten years, we've had the good fortune of ordering thousands of bulbs from A.D.R. each fall to help further beautify Newport, RI. Not only is the quality of the bulbs outstanding, so is their customer service and attention to detail.

Dahlia 'Bumble Rumble' is a charming collarette variety with soft pink outer petals overlaid in raspberry tones that fade before reaching the tips. A smaller ring of white petaloids encircles the bright yellow center, creating a striking contrast. Blooms typically measure 3 to 4 inches in diameter. Flowering from midsummer until frost, 'Bumble Rumble' grows to about 36 inches tall and thrives in full sun with well-drained soil. Especially attractive to pollinators—particularly bees, which often gather at its open centers—it’s an excellent choice for borders, beds, and cutting gardens.

Planting: In spring, plant tubers 3 to 4 inches deep with the eye facing up, once soil has warmed to at least 60°F. Space 18 to 24 inches apart to allow for airflow and mature spread.
Location: Full sun (6–8 hours daily) is essential for strong stems and vibrant blooms.
Soil: Well-drained, fertile loam with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost or well-rotted manure before planting.
Watering: Water deeply 1–2 times per week, keeping soil evenly moist but not soggy. Mulch helps retain moisture and regulate temperature.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift tubers after frost and store in a cool, dry place.
Fertilization: Apply a balanced fertilizer (e.g., 10-10-10) monthly or use a slow-release formula. Avoid high-nitrogen feeds.
Pruning: Pinch back when plants reach 12 inches tall to encourage bushiness. Deadhead regularly to prolong bloom.
Pest & Disease: Watch for aphids, slugs, and fungal issues. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each has at least one viable eye.
