Plant as early as possible in spring, as poppies can handle frost and bloom best and longest when plants get a good start in cool weather. In mild winter climates, sow seed in late fall to overwinter for spring bloom. Weed and water young seedlings carefully. Mature plants can handle dry conditions but appreciate regular water in hot locations.
BEST TO START DIRECTLY IN THE GARDEN
Sow seeds directly into a finely textured garden bed in full sun as early in spring as ground can be worked. To help space the fine seeds, mix with dry sand before sowing. Cover very lightly with fine soil and keep seed bed moist as seedlings emerge over 7 to 14 days.
