Poppy seeds require a period of stratification in order to germinate. That means they need to be exposed to cold or frost before they'll sprout. It's usually a safe bet to sow poppy seeds in very early spring, while there's still a good chance of frost. If you're in an area with mild winters, sow the seeds in the fall, so they get plenty of exposure to cooler temperatures before the weather warms up in the spring. After 14 to 28 days, the seeds will begin their germination, sending up shoots. Poppies are sown on the surface, rather than buried in holes. To prepare the soil, simply loosen its surface a bit with a garden rake. There's no need to till it to a depth of more than an inch or so, if that. In fact, doing so may make it more difficult for your poppies to grow. Sprinkle them over the freshly loosened dirt. In nature, poppies drop their seeds, which are small enough to easily be scattered across the ground by the wind. In this spirit, scatter the seeds and let them fall where they may, rather than trying to plant the poppies in rows. It will be difficult to keep the seeds confined to the spot where you drop them. Keep the area moist by sprinkling water over the soil. Don't soak it, though, or you may drown the delicate seeds. The seedlings will sprout when the weather warms in the spring. Thinning helps the plants to get bigger and produce more flowers. To thin it is a good idea to cut the plant tops off that you are thinning with scissors so  not to disturb the remaining poppies roots. When you see them sprout, you can thin out the poppies to allow each plant a bit of room to grow. Different varieties will come with different instructions as to how much spacing they need. This step isn't totally necessary, but it can give you more control over the final appearance of your flower bed. They do well in poor soil that other plants may not be able to survive in. The blooms will fall off and the pods will remain. You can harvest these to plant next season. Some varieties even produce edible seeds you can use to make treats such as poppy seed muffins. Most poppies don’t need much water once they have grown in a bit. In fact, over watering can create leggy, unattractive growth.  Water your poppies moderately and regularly when they’re in bloom or are almost in bloom. After the flowering period, only water your poppies when the top inch of soil is dry to the touch.
ابذر البذور في الربيع أو الخريف. فكك الوحل في منطقة الزراعة. ابذر البذور. اسق البذور. خفف الخشخاش. انزع البراعم حين يبدأ الإزهار لتضمن استمرار نموها، وهي تبلي حسنًا في التربة الضعيفة التي لا تعيش بها النباتات الأخرى. اترك قرنات البذور تتكون عند حلول الصيف. اسق الخشخاش باعتدال حين يرسخ.
