Many species of wetland seed need to be cold stratified to germinate. Many species also need light to germinate. Because so many of the species in our seed mixes need light to germinate, we do not recommend hydroseeding. We suggest broadcasting the seed, then lightly raking it in.
Cold stratification simulates the effect of winter weather on the seeds.
Twelve to 24 hours of soaking should be sufficient for seeds without hard seed coats or coverings. The medium should be moist but not so wet that water can be squeezed out. Check and turn the seeds regularly to ensure they do not dry out. Warm stratification is an identical procedure, only the seeds should be stored at room temperature rather than refrigerated.
