Everyone loves zinnias – at least, everyone whom I come across does. They are such vibrant flowers and superb cut flowers, and they flower for weeks on end. The only hiccough is the leaves can get powdery mildew in humid areas. Other than that, they’re easy-care.
Head to your garden centre and you’ll find zinnias in the potted colour section, or in multiple seedling packs. Plant in a sunny spot in the garden and feed and deadhead regularly for a continuous supply of blooms. If you do that, your zinnias will flower right throughout summer and autumn.
If you want to grow your zinnias as cut flowers, snip off the centre flowers when plants are about 40cm high (do this on regular zinnias, not bedding, or dwarf, zinnias). This encourages the plants to branch low and produce taller stems.
