Dahlia 'Yellow Jill'
decorative dahlia tuber
- Position: full sun
- Soil: fertile, humus-rich soil
- Rate of growth: average
- Flowering period: July to September
- Hardiness: half hardy (may need winter protection)
The perfectly formed heads of these unusual dahlias are made up of mahogany tipped yellow 'petals', which turn rich amber as they age. It looks wonderful when woven through a border with a tropical feel, and they will add lashings of colourful blooms over several months from midsummer. - Garden care: 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.
