Dahlia Cactus – Cheerio | 1 Bulb

Bright, buoyant, and bursting with good cheer — the Cheerio Cactus Dahlia is a variety that brings an instant lift to any garden it graces. Its blooms erupt in a breathtaking starburst of long, quilled petals in vivid, jubilant colour that radiates warmth and positivity from the moment the first flower opens. Uplifting in spirit, generous in bloom, and impossible not to love, this is a dahlia that makes every day in the garden feel like a celebration.

A crowd-favourite of the cactus dahlia group, Cheerio produces large, fully double blooms with narrow, pointed petals that radiate outward in a bold, spiky silhouette. Its cheerful, vibrant tones create a striking contrast against lush green foliage, making it an exceptional choice for sunny garden borders, cutting gardens, and bright, joyful floral arrangements that spread happiness wherever they go. This listing includes 1 bulb — because every garden deserves a little Cheerio.

Soil & Position

Dahlias thrive in well-draining soil. If your garden has heavy clay, incorporate sand and compost to improve drainage and aeration. A layer of mulch over the soil surface will help retain moisture between waterings. Select a position in full sun — they can tolerate midday shade, which also reduces their water requirements. When planting, ensure tubers are positioned with the growing points facing upward.

Care & Maintenance

Feed regularly with Hadeco Bulb Food to promote vigorous growth and abundant blooms. Taller varieties may require staking as they develop. Routine pruning encourages fresh growth, and pinching out the two side buds flanking the central bud will channel the plant's energy into producing one magnificent, oversized flower.

As the season draws to a close, yellowing foliage is entirely natural — remove it as it dies back. To lift bulbs for winter storage, cut stems approximately 5 cm above ground level in July and carefully lift the tuberous root. Well-nourished bulbs will yield a generous increase in tuber size and quantity around the crown. Keep roots completely dry during storage.

Should you observe deformed growth, stunted development, or mottled foliage, remove and discard the affected plant immediately — these are indicators of infection.
