Growing Dahlias: Sun, Soil, and Care for Spectacular Blooms

Dahlias are among the most beautiful, exotic garden residents. Large blooms (1 inch to 1 foot) in varied colors and shapes—some like baseballs, others curving back to touch their stems—make them stars of any garden or flower show.

Growing Requirements

• Sun: At least half a day of direct sunlight.
• Water: 1–2 inches per week (rain or irrigation).
• Soil: Rich, with ample organic material.
• Maintenance: Regular pruning, staking as they grow, quality low-nitrogen fertilizer, insecticide for beetles/grasshoppers.

Planting and Overwintering

Dahlias grow from tubers (classified as bulb plants). Plant early June for October bloom; earlier planting gives late summer flowers. Dig up after first frost, divide tubers, store for winter, replant next year.

Popular Varieties

• David George: Deep red, medium bloom.
• Bonaventure: Large bronze flowers.
• Allie Yellow: Tiny yellow blooms.

Dahlias are staples at flower shows alongside orchids and roses, prized for striking beauty and size.
