Zinnias are easy-to-grow flowers that add a bright touch to any garden and wow you with their beauty. Start zinnias before frost indoors or direct sow after frost in a prepared garden bed or container. When planting outside, choose a sunny location. Space the seeds 1 to 2 inches apart and cover with 1/2 inch of soil. Cover seeds lightly as zinnia requires light to germinate. Water the seeds generously.
Zinnias don't like to be transplanted, but can be started indoors 4-5 weeks before the last average frost. If starting indoors, plant one seed in each peat pot or soil block in seed-starting mix and place the pots next to a window where they will receive at least 6 hours of sunlight a day. Transplant zinnias to a sunny location when they are approximately 3 inches high. Wait until all danger of frost has passed. Keep the soil evenly moist during germination. A watering can is recommended outdoors to gently water the seeds without disrupting the germination process. If necessary, thin the plants to leave 2 to 3 inches of space between them.
Pinch the plants back when they reach 18 inches tall. This encourages branching, which produces additional blooms. However, for the largest single bloom, do not pinch the plant back.
Enjoy fabulous giant blooms all summer long. Cut some to bring inside; they make long-lasting cutting flowers.
Deadhead the plants as the blooms fade to extend the bloom period.
