Dahlia 'Café au Lait Royal'
Dahlia 'Café au Lait Royal' is a decorative dahlia grown for generous, ruffled blooms that read as soft blush-pink from a distance, with white and lilac tones up close. It’s a standout for borders and for cutting—perfect when you want romantic, pastel stems.
For best results, start tubers in pots from March or April in a frost-free place, then plant out once the risk of frost has passed. Choose full sun and a warm, sheltered position, and mix in plenty of garden compost to improve structure and drainage.
Plant tubers about 10–15cm deep with the ‘eye’ facing upwards, spacing plants roughly 45–60cm apart. Keep the soil evenly moist as shoots develop. If you’re growing taller stems or larger flower heads, add a cane early so support is in place before flowering.
Water deeply in dry weather and feed every two to three weeks through summer with a high-potash fertiliser to encourage buds. Deadhead regularly and cut stems often—removing spent blooms helps direct energy into new flowers, giving you a longer, heavier display.
After the first frosts blacken the foliage, cut stems back and lift the tubers to store somewhere cool, dry and frost-free. In very mild areas you can mulch heavily, but lifting is safest. Replant next spring and you’ll usually see stronger plants each year.
