Zinnia, Burpee's Big Tetra Mix

How to Sow Zinnias

Sow in average soil in full sun after danger of frost. Sow seeds about 12" apart and cover with 1⁄4" of fine soil. Firm lightly and keep evenly moist.

How to Grow Zinnias

Seedlings emerge in 7-10 days. Thin to stand 18-24" apart when seedlings are 1-2" tall. Zinnias need good air circulation to help prevent powdery mildew. Water seedlings regularly until they are established. After that, zinnias do not need watering except during extended droughts. Pinch plants to encourage branching, unless you are growing them exclusively for cut flowers and want long stems. Deadhead regularly to keep plants flowering until fall.

Harvesting Zinnias

Plant zinnias in mixed plantings with other summer-blooming annuals, or place small groups of zinnias among perennials. They are at home in cottage gardens and children's gardens, and they are often grown in cutting gardens. Cut the stems before the flower is completely open. Zinnia flowers also attract hummingbirds, butterflies, and beneficial insects.
