Dahlia Pink

Dahlia ‘Pink’ is a brilliant way to add classic, feel-good colour to the summer garden. Its blooms open in gorgeous pink shades—fresh, vibrant and wonderfully versatile—making it easy to pair with almost anything in the border. Whether you love a romantic cottage-garden look or prefer a brighter, modern planting scheme, pink dahlias are always a winner, bringing long-lasting colour from midsummer right through to the first frosts.

It’s also a fantastic cut flower. The more you pick (or deadhead), the more blooms you’ll get—so you can enjoy flowers in the garden and in the vase for weeks on end

Planting Instructions

When to Plant:

Plant Dahlia tubers in spring. For the earliest flowers, start tubers in pots indoors from March to April, then plant out once the risk of frost has passed. If planting directly outside, wait until late spring when the soil has warmed.

Where to Plant:
Choose a sunny, sheltered position with fertile, well-drained soil. Dahlias are ideal for mixed borders, cutting gardens and patio containers. They love warmth and perform best in full sun.

How to Plant:

• Depth: Plant tubers about 10–15 cm (4–6 inches) deep, with the old stem (or growing point) facing upwards.
• Spacing: Space plants 45–60 cm (18–24 inches) apart, depending on the final size.
• Soil Prep: Enrich the planting area with well-rotted compost or manure. In heavy soil, improve drainage with grit.

Watering:
Water after planting. Once shoots appear and growth is underway, keep soil evenly moist, especially in dry spells. Avoid waterlogging. Container-grown Dahlias may need watering daily in hot weather.

Aftercare Tips:

• Pinch out the growing tip once plants are around 30 cm tall to encourage bushier growth and more flowers.
• Stake taller stems if needed, especially in exposed borders.
• Deadhead regularly (or cut for the vase) to keep plants flowering until autumn.
• After the first frost blackens the foliage, lift tubers and store dry and frost-free over winter, or protect in the ground with a thick mulch in milder areas.

Top Tip:
Pink dahlias are brilliant for mixing and matching—pair with whites for a romantic look, or add purples and deep reds for a bolder, more dramatic border.
