Dahlia 'Great Hercules'

decorative (dinnerplate) dahlia

Product Image
Magnificent heads up to 20cm across are packed with slightly ruffled, chunky 'petals', each with a pointed tip. When they first start to appear, these are initially bronze with just a hint of pink, but their colour quickly changes to soft orange as they unfurl fully. It looks stunning when teamed with rich plums, claret red or warm yellows.

How to care for Dahlia Great Hercules:

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.
