Dahlias are half hardy, so keep them protected from frost. Pot tubers individually between February and April and grow them on in a greenhouse or bright indoor position. Alternatively, start them outside in May, once the risk of frost has passed.

Dahlia
'Maxime'
If you appreciate art, you’ll love the amazing mandala-like blooms of Dahlia 'Maxime'. Each unique flower is a masterpiece of soothingly symmetrical design with precisely sequenced petals which form the most wondrous whorls. Every scarlet red petal is edged with an ultra-fine golden margin, defining that distinct and attention-grabbing petal pattern. In addition to its dazzling, exotic looks, Dahlia 'Maxime' is strong and robust. Blooms are produced by the plenty through summer and autumn. They last well and the generous, sturdy stems make it a worthwhile candidate for the cutting patch. With all that going for it, it’s not surprising if you feel powerless to resist the divine Dahlia 'Maxime'!
Dahlias are the superstars of the late summer garden and Dahlia 'Maxime' is no exception. All dahlias tend to be at their peak in late August/September and that’s the case whether they’re planted in early or late spring. If you can’t wait to see your dahlias, encourage your 'Maxime' dahlias to start flowering from as early as June by potting them up indoors in early spring and growing them on before planting them out after risk of frost has past. Keep cutting and deadheading these fantastic flowers through the season and more will continue to grow, all the way up until the first frosts.

For planting out later, use a snug-fitting 15–20cm pot filled with peat-free multipurpose compost. For a patio display, plant directly into a container at least 30cm wide and keep it somewhere bright and frost free until it can move outdoors.
Position the old stem facing upwards, with the tubers covered and the stem stump level with the compost. Tubers naturally vary in size and shape and may arrive without visible buds. Bent necks are usually fine if they remain firmly attached, so do not remove them.
Water after planting, then allow the compost to become almost dry before watering again while the tuber remains dormant. Once shoots and leaves are growing strongly, water more regularly, always allowing excess water to drain away.
Plant out after the last frost, once the plant is around 20–30cm tall and its roots hold the compost together. Space dahlias approximately 30–50cm apart in borders, allowing less room for compact varieties. Water thoroughly after planting.
Water regularly during active growth and deadhead or cut flowers often. Dahlias usually bloom from July or August until the first frost, although later-planted tubers may start in late August or September. In autumn, lift, clean and dry the tubers, then store them somewhere cool, dry, airy and frost free.
