Plant Propagation:
Zinnias are grown from seed. Zinnia seeds can be directly seeded into your flower garden, or seeded indoors for transplanting later. We recommend planting Zinnia seeds in pots and containers indoors, then transplanting them outdoors. This allows you to make the proper spacing and not have to thin seedlings.
Sow Zinnia seeds early in the season and cover lightly with soil. Water thoroughly once. The seeds germinate easily, and grow quickly, producing their first of a continual display of blooms, by mid-summer.
Transplant young Zinnia plants into your garden after the last frost date for your area. Spacing depends upon size, with miniature varieties spaced four to six inches apart, and Giant varieties one to two feet apart.
Days to Germination: 5 - 10
How to Grow Zinnia Plants:
Growing Zinnias is a cinch! They are one of the easiest flower plants to grow in your home flower garden.
Grow plants in full sun. They like warm to hot weather.
Zinnia plants like rich, well drained soil. But, they are very tolerant of average to slightly poor soils. Improving your soil quality will produce much healthier plants and flowers, so add plenty of compost. Add a general purpose fertilizer once a month, especially with average soils.
Once Zinnia plants are established, they should grow well. Soil should be moist, but not wet. Water plants during dry periods, once or twice per week.
Add mulch around the plants for appearance, and to keep weeds down.
Around mid-summer, your Zinnia plants will begin to produce flowers. The blooms will continue, up to the first frost. Remove dead flower blooms, to encourage new growth and blooms. Improve appearance of Giant Zinnias, by trimming back stems that have grown long or gangly. Do not over trim them.
Zinnias are annuals, and are susceptible to frost. They may survive the first light frost with only a little damage. They will not survive a hard frost or freeze.
Flowers Bloom: Summer thru Fall
Cuttings for Indoors:
Giant Zinnias have long stalks for flower vases and other arrangements. Cut the stem low, check for insects hiding in the flower head, on the stem, and under the leaves. Bring them indoors and place in water immediately.
For miniatures, use a small container or vase and cut stem a couple inches long. Bunch up a variety of colors for an eye-appealing arrangement. Add a small sprig or two of Baby's Breath.
Insect and Disease:
Zinnias are somewhat resistant to insects and disease. If insect or disease problems occur, treat early with organic or chemical insect repellents and fungicide.
