I just received a packet of California poppy seed. Can I plant them now (Sept) in Illinois?
Planting Poppy Seed
Certified GKH Gardening Expert
Direct sow your seeds outside in early spring. Prepare the area by raking loose the top few inches of soil, plant the seeds and cover lightly (only about 1/8 in. deep). Keep the soil moist after planting until the seeds germinate in 14 - 28 days, depending on the temperature.
