Growing and Maintenance Tips for Dahlia Blend 'Rainbow Mix' (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 varying growth habits.
Location: Full sun (6–8 hours daily) is ideal for all types. Taller varieties may benefit from wind protection or staking.
Soil: Fertile, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost 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.
Pruning: Pinch back when plants reach 12 inches tall to encourage bushier growth. Deadhead regularly to promote continuous bloom.
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.
