Once your poppies begin to sprout, use a spray bottle and give the seedlings a good few sprays to moisten the plant and wet the soil. The roots are extremely sensitive at this stage, and a big waterfall from a watering-can could kill your plant on the spot. Try to water in the morning or the afternoon. Night-time watering can encourage fungus growth. Also, try to give your poppies as much sun as your situation will allow. If you pay close attention to your plants, and maybe experiment here and there with some fertilizers, you'll most likely have an incredible looking poppy garden within a few months.
