How to grow zinnias
Cut them and they flower more.
Overview
Zinnias are heat-loving annuals grown easily from seed. They flower for months and make excellent cut flowers — in fact cutting them is what keeps the plant producing.
Common problems and what to do
Powdery mildew
The main zinnia problem. Space generously, water the soil not the leaves, and remove affected foliage.
Short, single stems
Pinch the growing tip of young plants to get branching and more cutting stems.
Flowering slowing down
Old blooms left on the plant. Cut or deadhead often.
Harvesting
Cut when the stem below the flower feels firm rather than floppy — a wobbly stem means it is too early.
Beginner tips
- Sow direct rather than transplanting; zinnias resent root disturbance.
- Pinch once at about 12 in (30 cm) tall for far more flowers.
- Plant a row alongside vegetables to draw in pollinators.
