Provide horisontal plant support when growing in windy areas. Water often in summer and feed regularly with a low Nitrogen fertiliser.
Harvest early morning and into fresh, clean water. A "cut and come again" favourite, dahlias produce for months when harvested frequently. Don't be afraid to cut tall stems so that new growth can branch out from lower down on the plant.
