Viability of grain for seeding
Seed is a living entity and once it is mature, it will begin to deteriorate. The rate of deterioration depends on;
- the species
- initial quality of the seed
- harvest and handling of the seed
- storage conditions.
Prior to seeding, get your retained seed tested by a seed testing laboratory such as DDLS Seed Testing and Certification or do your own germination test (see this page).
