Do zinnias reseed themselves?
Zinnias (Zinnia spp.) reseed easily, creating a cut-and-come-again garden each summer. Heirloom varieties, cultivated for more than 50 years, are open pollinated and grow into plants identical to their parents. Zinnia hybrids also reseed but may look quite different.
Can you get seeds from cut flowers?
When you’re ready for seed harvesting, you’ll need to know the best method on how to collect flower seeds.

Should you soak zinnia seeds before planting?

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.
What month do you plant zinnias?

Can zinnias grow in pots?

How many zinnia seeds are in a hole?
Plant seeds 1/4″ deep and 24” apart, using 3 seeds per hole. Keep the soil evenly moist until the seeds germinate in 8 – 10 days. Once the seedlings reach 2″, thin out so you have individual plants spaced 24” apart. Water regularly allowing the soil to go nearly dry between each watering.
