You must extract the water from harvested morning glory seeds before you store them. Otherwise, the water in the morning glory seeds can cause them to develop mold. This mold may kill the seed, preventing germination. Or, the mold may attack the germinating seedling and kill it before the plant can mature. One way to speed the drying process is to let mother nature do some of the work. Leave the morning glory seeds on the plant until the pods are brittle, brown and dry and the seeds rattle around inside.
Pick the dried morning glory seed pods from the plant.
Empty the seed pods onto the plate. Simply crumble the pods between your fingers. The mature seeds will fall out. Immature seeds will remain in the pod.
Spread the morning glory seeds out on a plate in a dry, well-ventilated area that remains room temperature. Leave them to air dry for at least 48 hours or until completely dry to the touch. Shake the seeds around once daily to make sure that they dry evenly on all sides.
Pour the morning glory seeds into a glass container and store in a cool, dark place until you are ready to use them.
