We love the selection of bulbs available from A.D.R. The variety is great, the quality is excellent and the price is fair. However, the best part of working with A.D.R is the customer service from Chris, Walter and all of the team. They go out of their way to make sure ours needs are met.

Growing and Maintenance Tips for Dahlia Decorative 'Sam Hopkins' (Ships in Spring)

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 accommodate their full, bushy growth.
Location: Full sun (6–8 hours daily) is essential for strong stems and prolific blooms.
Soil: Fertile, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost or aged manure before planting.
Watering: Water deeply once or twice a week, keeping soil evenly moist but not soggy. Avoid watering until shoots emerge to prevent rot.
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 monthly or use a slow-release formula at planting and midsummer. Avoid high-nitrogen feeds to prevent leggy growth.
Pruning: Pinch back when plants reach 12 inches tall to encourage branching. Deadhead regularly to extend bloom time.
Pest & Disease: Watch for aphids, spider mites, and fungal issues. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each division has at least one viable eye.
