Will the seeds I have left over from last season still germinate?

Different types of seed will have different lengths of life and there is no general rule as to how long seeds will remain viable.  The conditions under which they are stored will affect the life of the seed and they should generally be kept somewhere cool and dry. 

Many types of seed are now sold in foil packets to maintain the freshness and viability.  Once these packets have been opened the natural ageing process will begin.  Some types of seed such as Impatiens and Parsnips have a very short life and fresh seed should be used each season.   Runner Bean seed will generally remain viable for up to 3 years.   

If old seed is to be used it is best to make a test sowing first.
