1. Soak the seeds for 24 hours in warm water. Soaking seeds in warm water with a dash of dish soap prior to stratification has helped improve the germination. It is thought that the soap pierces any oily residue on the surface of the seed allowing water to be imbibed.
2. Place the seeds in a handful of just slightly moist sand or vermiculite and then into a plastic ziplock bag. Seal the bag and leave it in the refrigerator for 60 days.
3. Sow seeds about 1mm deep in a Well drained seed sowing mix at about 12°C.
4. Ostrya seeds will germinate after the stratification done. Sometimes takes a long time, so please be patient.
