Growing and Maintenance Tips for Dahlia Dinnerplate 'Mingus Alex' (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 24 to 36 inches apart to accommodate their tall stature and massive blooms.
Location: Full sun (6–8 hours daily) is essential. Choose a sheltered spot to protect from wind, as the large flowers can be top-heavy.
Soil: Rich, loamy, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Amend with compost or decomposed leaves for aeration and fertility.
Watering: Water deeply 1–2 times per week, increasing during hot, dry spells. 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: Feed every 2–3 weeks with a balanced or low-nitrogen fertilizer. Overfeeding nitrogen can reduce bloom size.
Pruning: Pinch back when plants reach 12 inches tall to encourage branching. Disbud (remove side buds) to direct energy into fewer, larger blooms. Deadhead regularly to extend flowering.
Staking: Essential. Use tall stakes or cages early to support stems and prevent flopping under the weight of 10–12 inch blooms.
Pest & Disease: Watch for aphids, spider mites, and powdery mildew. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each has at least one viable eye.
