When to Plant Zinnia Seeds in Missouri

The best time to plant zinnia seeds in Missouri is in early spring, after the last frost date. Zinnia seeds can be started indoors about six weeks before the last frost date, or they can be direct-seeded outdoors after the soil has warmed up to at least 60 degrees Fahrenheit.

If you are starting zinnia seeds indoors, sow them in small pots filled with a well-draining potting mix. Cover the seeds with a thin layer of soil and mist them with water. Place the pots in a warm, sunny spot and keep the soil moist until the seeds germinate.

Once the seedlings have sprouted, thin them out so that they are about 6 inches apart. When the weather is warm and settled, you can transplant the seedlings outdoors. Space the plants about 12 inches apart.

Harvesting Zinnias

Zinnias are ready to harvest when the petals are fully open. Cut the flowers from the stem with a sharp pair of scissors. Zinnias can be used fresh in bouquets or dried for arrangements.
