Poppies should be watered regularly, but they can tolerate dry conditions. The entire peat pot can then be planted outdoors once the poppy seedlings are established. However, if necessary, they can be started in biodegradable peat pots indoors before the last spring frost. Poppies do best if planted directly outdoors in their intended location rather than transplanting them. If planting in rows, then plant the seeds 6” to 8” apart. You can thin the seedlings to 6” to 8” apart after they emerge. These varieties of poppy seeds generally germinate in about 20 days. The best method for planting is to mix one part seed with 5 parts sand and scatter over the prepared growing area. The seeds should not be planted deeply they just need to be covered with soil. Poppies only need soil that is ordinary and moist, but well drained. In zones 8 – 10, these poppy seeds should be sown in late autumn or winter. 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. Bloom decreases on poppies as temperatures increase in summer months. Poppies flower best under cool spring weather conditions. These poppies germinate most successfully in cool to moderate temperatures and they are, in fact, frost tolerant. Papaver Rhoeas act as perennials in moderate climates, but they perform as annuals where freezing temperatures and snow occur in winter. ![]()
