Dahlia Border – Carola | 2 Bulbs

Lush, luminous, and wonderfully generous — the Carola Border Dahlia is a variety that brings a warm, peachy glow and abundant charm to garden borders and beds. Its blooms open in layer upon layer of softly cupped petals in a rich, apricot-salmon tone that radiates warmth and welcome. Gentle in character, prolific in bloom, and deeply satisfying to grow, this is a dahlia that fills the garden with a soft, glowing radiance from December right through to May.

A much-loved classic of the border dahlia group, Carola produces beautifully formed, fully double blooms in a warm peachy-salmon hue that harmonises effortlessly with both cool and warm planting palettes. Its compact, free-flowering habit makes it an ideal choice for garden borders, patio containers, and heartfelt floral arrangements that bring warmth to any space. This listing includes 2 bulbs of this radiant variety.

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.
