As for all poppies, best time to be sown is late
autumn or early spring. The snow of winter helps "challenge" the poppies to grow good rooting systems, which results in a strong plant. Spacing for plants should be at the minimum of because the roots do not grow deep, and after just a few centimetres they start growing horizontally. The disadvantage of their roots is that poppies do not do well being transplanted. Caution must be taken when transplanting from peat pots. Another problem with the roots of any type of poppy is that the roots will rot if they do not have proper drainage. One should not over water, and to prevent complications one must use a spray bottle when
Papaver plants are maturing. ==Chemical composition==
