Growing Double Poppy Peony Seeds
In growing zones, 3 – 7, the Red Corn Poppy, Shirley Poppy – Mixed Colors, and the Shirley Poppy – Mixed Double seeds can be planted in late autumn or early spring when a light frost is still possible.
In zones 8 – 10, these poppy seeds should be sown in late autumn or winter.
WHERE TO PLANT POPPY SEEDS
Poppies only need soil that is ordinary and moist, but well-drained. They also do well in full sun.
HOW TO PLANT POPPY SEEDS
Poppy seeds need to be coldly stratified to germinate.
Papaver Rhoeas act as perennials in moderate climates, but they perform as annuals where freezing temperatures and snow occur in winter.
These poppies germinate most successfully in cool to moderate temperatures and they are, in fact, frost tolerant. Poppies flower best under cool spring weather conditions. Bloom decreases on poppies as temperatures increase in the summer months.
The seeds should not be planted deeply; they just need to be compressed into the soil, as they need light to germinate. The best method for planting is to mix one part seed with 5 parts sand and scatter over the prepared growing area.
If planting in rows, then plant the seeds 6” to 8” apart.
HOW TO CARE FOR DOUBLE POPPIES
These varieties of poppy seeds generally germinate in about 20 days. You can thin the seedlings to 6” to 8” apart after they emerge.
Poppies should be watered regularly, but they can tolerate dry conditions. It is not necessary to fertilize poppies.
It generally takes about 60 to 90 days for poppies to bloom after the seed is planted. This timing depends very much on your growing zone and when you plant, along with Mother Nature’s cooperation.
The bloom season for poppies is spring to summer. Poppy plants will bloom for a few weeks, but the length of bloom time can be extended by regular watering and application of mulch for moisture retention, as well as regular deadheading of spent flowers.
It is also recommended that the seed be sown in successive plantings to extend the bloom season of the poppies.
