Zinnias are one of the most enjoyable plants to grow because of their large brightly colored flowers. In addition, they make good cut flowers. They are a good choice for the beginning or weekend gardener, and will produce blossoms from early summer into fall. Although there are numerous varieties, it is not always easy to find them in established plants. Therefore, it is sometimes necessary to start them from seeds if you are a looking for a particular type of zinnia.
Zinnias require a sunny location, and soil that drains well. If you are planning on growing them from seed, wait until there is no danger from frost before sowing them. Plant them about one quarter inch deep, and cover loosely with soil. They germinate fairly quickly and will need to be thinned to at least 6 inches apart. Follow the directions on the seed package, as the distance between plants will vary depending on the size. Water them well. If you are purchasing established plants, space them 8 to 12 inches apart. Dig a hole large enough to accommodate the dirt enclosures in which they came. Water thoroughly. Try to avoid getting water on the leaves, as this will encourage disease. Remove dead flowers to allow the plant to spend its energy on creating more blossoms.
