Clear the planting bed of debris and weeds as soon as the ground thaws in spring. Poppies grow in cool weather. Select a planting site in full sun.
Break the ground with a shovel and spread 2 inches of manure or compost on the turned surface. Blend the organic matter with the soil to improve drainage. Rake the planting bed to smooth it out for planting.
Mix 1 part poppy seeds with 3 parts sand to keep the seeds separated from each other as you sow them.
Broadcast the poppy seeds on the surface for sunlight to reach them, promoting germination. Do not worry about spacing in this step. Throw a fine layer of soil over the light seeds to give them some protection from the wind.
Water the seeds using a soaker hose laid about 2 inches from them. The hose style provides a gentle method of keeping the seeds moist without dislodging them. Maintain the seedbed hydrated until the poppy seeds sprout. Germination occurs in about two weeks.
Thin 1-inch-tall seedlings to 6 inches apart. The spacing allows for adequate air circulation, which prevents fungal diseases.
