How To Use Dahlias In The Garden
Dahlias, originally from Mexico, are well-known for their wide range of sizes, shapes, and colors. These tuberous plants are prolific bloomers from summer through fall, with flowers resembling balls, orchids, or pompons. Dahlia heights vary, but most grow to about 18 inches high and wide. A single tuber can multiply significantly within a season and create new plants to spread around the garden and share with friends.
Place shorter dahlias at the front of borders or in containers, where their unique blooms can be admired up close. Tuck taller varieties among perennials or ornamental grasses so their heavier stems are supported and lower foliage is hidden. Group them in sunny locations where consistent deadheading and occasional staking can keep plants looking neat. Consider selecting multiple sizes and colors to add eye-catching late-season interest and provide long-lasting cut flowers.
Dahlias Care
Plant dahlias in a sunny spot with at least six hours of light daily. Use well-draining soil with a pH of 6.5–7.0, and amend heavy soils for better drainage. Water sparingly until sprouts emerge, then provide about an inch weekly. Fertilize with low-nitrogen formulas like 5-10-10 to encourage growth and flowers.
Pinch stems early for bushier growth and deadhead regularly to extend blooming. In zones 8–10, cut back foliage after frost and mulch; in colder zones, dig up, clean, and store tubers in a cool, dry spot. For container growth, use a high-quality potting mix, water frequently, and fertilize bi-weekly during the growing season.

Dahlia Companion Plants
Give every plant at Dahlia’s side the same essentials—six‑plus hours of direct sun, loose soil that drains fast yet holds moderate fertility, and irrigation that keeps roots moist without waterlogging the tubers. Peonies and Shasta daisies stage the spring prelude, their sturdy stems and cool‑toned blooms fading just as dahlias rise to assume the starring role, so the border never lacks for color. All season long, airy bacopa weaves through the clumps to disguise bare stems while petunia carpets the front, echoing Dahlia’s hot shades and luring pollinators until frost.
