Successful germination begins with viable seed, a suitable growing medium, appropriate moisture, and the temperature and light conditions needed by that variety.
Sow at the depth recommended for the seed. Very small seeds are often sown shallowly, while larger seeds may be covered more deeply. Keep the medium evenly moist rather than waterlogged.
Germination time varies widely. Check the packet or variety-specific guidance before deciding that a seed has failed.
