Do zinnia seeds have to dry on plant?

What do viable zinnia seeds look like?

The seeds will be arrowhead-shaped, pointed on one end and broader on the other, each having a raised spine running up its back. They will measure about 3/8 to 1/2 inch long, if harvested from medium-sized zinnias, and usually slightly less than 1/4 inch across at their widest point and brownish in color.

How do you separate zinnia seeds from chaff?

Put the seed and chaff on a cookie sheet and place the cookie sheet on the box. Turn a fan on so the air blows across it and lift the end of the cookie sheet so the seeds roll down. If need be, repeat until the chaff has blown off. Sieves can also work to winnow the chaff from the seed.

Can zinnias be dried?

To dry dahlias, plumed celosia, zinnias, roses, marigolds, and other flowers with thick heads or delicate blooms, use a drying agent–borax, white cornmeal, rice, or silica gel (available at craft shops). These materials draw the moisture out of plant tissues while still retaining flower color.

Growing Zinnias From Seeds Plant the seeds only about ¼-inch deep. You’ll see seedlings sprout in four to seven days. Once the seedlings reach about three inches tall, thin them so that they’re 6 to 18 inches apart to maximize air circulation, a key to keeping zinnias looking good all season.

Do zinnia seeds need stratification?

The ancestors of our hybrid garden zinnias (Zinnia spp.) are plants native to Mexico, Central America and South America. They grow in hot climates without cold winters, so seeds don’t need cold treatment to germinate. Rather, they need warm temperatures, plenty of moisture and sunshine to germinate and grow well.

Do zinnias reseed themselves?

Zinnias (Zinnia spp.) reseed easily, creating a cut-and-come-again garden each summer, says the University of Wisconsin Extension. Heirloom varieties, cultivated for more than 50 years, are open pollinated and grow into plants identical to their parents.

Should you soak zinnia seeds before planting?

It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced, which means you can have happy, growing plants faster.

Do zinnia seeds need light to germinate?

Zinnias are very low-maintenance and simply need lots of sun, warmth, and well-drained soil in order to thrive and can be enjoyed from summer until the first heavy frost of fall. Cover zinnia seeds with just ¼ inch of soil because they need light to germinate. • Keep soil moist as the flowers develop.

Do zinnias come back every year?

Zinnias work year after year. It’s easy to save zinnia seeds. Simply let the flowers dry fully on the stem, then collect the seedheads and lightly crush them in your hand to release next year’s seed crop.
