How to care for A tale of summer blooms dahlia collection:
Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being overcrowded.
While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch.
In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.

What's included:
In each collection you will receive one tuber of each of the following:
Dahlia 'White Isa': Initially the petals are inrolled, and are a soft lemon-cream with just a hint of pink, but as the 7cm (3in) wide flowers mature fully, the petals flatten out and become paler. Creating a sublime and slightly ethereal effect, the flowers are excellent for bouquets or borders. Grows to 80cm.
Dahlia 'Purple Gem': A tuberous-rooted perennial with mid-green foliage and striking cactus-style flowers from mid-summer to the first frosts. Its rich purple blooms, up to 12 cm (4.7in) across, have quilled, spiky petals that deepen in colour towards the centre, carried on strong burgundy-purple stems. 'Purple Gem' is an excellent and popular cultivar, that brings bold structure and long-lasting colour to borders, especially when paired with pinks, purples, and dark maroons. Thriving in full sun and moist, well-drained soil, it also makes a superb cut flower. Grows to 1.2m.
Dahlia 'Babylon': A remarkable dinnerplate dahlia cultivar, with its deep-red, double flowers spanning an impressive width of nearly 20cm (8in). 'Babylon' is a stunning tuberous perennial provides a burst of colour from midsummer through to autumn, gracing borders, patio containers and floral arrangements with a vibrant display. Grows to 1m.
