Invaluable as cut flowers, in patio pots or for the summer border, dahlias such as this ‘Red/Red-White’ Cactus mix are the perfect summer garden perennial. Containing a mix of either pure deep red or red and white variegated blooms, this curated combination will look stunning in any garden, blooming from July through to the first frosts.

Plant these dahlia tubers into well-draining soil in a sunny spot. The tubers should be planted approximately 15cm/6″ deep and spaced around 60cm/24″ apart. As the plants grow, they will reach a height of around 100cm/40″, making them a great choice for the back of a border or as a standalone feature. They will also be ideal as cut flowers.

For maintenance, regular deadheading is advised to encourage more blooms, alongside regular watering, making sure not to over-water as this can lead to the tubers rotting.
