Sow directly in the field
From April you can sow the snapdragon directly in the field. The substrate should be rich in humus and well loosened so that the seeds germinate without problems. Since the snapdragon is a light germ, these must not be covered with earth, or at best covered with a thin layer of earth. Spread a net over the seeds to protect them from hungry birds.

If you want to be sure that as many seeds as possible will sprout, it is advisable to have the snapdragon in the house preferable. Since the snapdragon is a cold germ, seeds that you have collected yourself have to be stratified beforehand. Put the seeds mixed with some sand in the refrigerator for a few weeks. Then do the following:
