Set plants 15 to 18 inches apart, and in full sun. Plants root deeply, so cultivate the soil well – a well-drained, good garden soil is best. We recommend a winter mulch the first year.
Water during periods of drought. Seed pods should be removed after the flowers are spent, and foliage should be cut back as it turns brown in midsummer. In planting, remember that the Oriental poppy dies back in midsummer and their foliage reappears in the late summer. A companion plant such as Gypsophila can fill the gap. Plants dislike being disturbed.
