Since poppies are moderately cold tolerant you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant poppies in Berne is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant poppies and expect a good harvest is probably September. You probably don't want to wait any later than that or else your poppies may not have a chance to really do well. You can get started a little bit earlier by starting your poppies indoors.
