Please read both the seed guide and the plant specific sowing instructions. If you are unsure of the best way to germinate the seeds, DO NOT SOW ALL THE SEEDS. Keep some in case the germination method you use doesn’t work.
Cold stratify ALL perennials, shrub & tree seeds for at least 30 days unless the plant specific instructions indicate a longer period. Seeds WILL NOT germinate if you do not stratify.
If you are not ready to plant the seeds, keep it in the refrigerator (not freezer).
