Hello.
Going to try a hybrid refrigerator/winter sowing stratification process in the fall/winter. In the past, I've used zip lock bags w/a little potting soil. Wondering...can you use just plain old sand? Or does something else work better? I've had ok success...though sometimes seeds grow mould and rot so I was looking for an alternative...any suggestions? I'm sowing seeds like Collinsonia canadensis, Elephantopus carolinianus etc...some of the seeds will be tiny.
What works for you? Thank-you!
