How to Raise Poppy Flowers From Seeds

Poppies (Papaver) are cool-season flowers. They bloom in spring and fall, decreasing production in the summer. The plants are perennial or annual, depending on the species, with heights ranging from 5 inches to 4 feet. Sow poppy seeds as soon as the ground thaws in late winter or early spring. Annual varieties self-seed, eliminating the need for planting them the following year. Select a species and cultivar hardy to your growing zone.

Instructions

    • 1

      Loosen the ground in an area of the garden that gets a minimum of six hours of sun daily. Select a site that drains within one hour of rain or irrigation. If drainage isn't as fast, incorporate 2 inches of compost into the ground to a depth of 4 to 6 inches. Rake the surface to smooth it out for planting.

    • 2

      Mix 1-part poppy seeds with 3 parts sand. The sand makes it easy to broadcast the very small seeds.

    • 3

      Sow the seeds on the soil surface 6 to 10 inches apart. If, despite the sand, it is difficult to pick the seeds one by one to space them out properly, plan on thinning the seedlings after germination.

    • 4

      Cover the seeds with a thin layer of topsoil. Some sunlight needs to reach the poppy seeds for germination to occur.

    • 5

      Install a soaker hose 2 inches away from the poppy seeds for gentle irrigation. Water the bed at planting. Maintain the soil moist to induce germination. When the soil temperature is at 55 degrees Fahrenheit, seedlings appear in two weeks.

    • 6

      Hand pull 1-inch-tall poppy seedlings to thin them to 6 to 10 inches apart.

    • 7

      Water established poppy flowers whenever the soil dries out. These plants thrive on little water and no fertilization. However, mulching them with a shallow layer of compost helps them to thrive.
