Using Old Seeds

[TheDrunkMonk]

Hi there

I've just found a tin of seeds that didn't get used when I moved house 2 years ago. Most say to sow by 2009 (spring/summer) but my question is: Is this date to do with how successfully they'll germinate? Or are there wider reasons, like the plants will be weaker or something? If it is solely germination, should I just try these seeds out and plant out the ones that grow?

depends on the seeds ... but try them on damp kitchen towel to see what your germination rate is...

There are a few notables that don't keep well - the worst seems to be parsnip. Brassicas and tomatoes can go well for 10 years after their use by date. I use them. If they don't come, THEN I shell out money!

Some seeds just die when kept too long - so they won't germinate. The proportion of seeds dying in a batch will increase over time - but it is always worth trying them out as suggested above as some may still be viable!

Thanks guys. I'll definitely give them a go next spring. I was amazed by how many different seeds I had. I do remember preparing for a very enthuiastic summer a few years ago at my old house, then moving. I must have packed them and forgotten about them.

I think a lot depends on how the seed is kept. If in a biscuit tin in a warm kitchen you may as well throw them out first as last, Also if kept in an old envelope in a damp shed.
But if kept cool and dry they can be viable for years!

Some seeds seem to be viable what ever you do with them. Have grown some very good lettuce this year from some old seeds (about 5 or 6 years old) which I found in a damp corner of the shed. Surprised me as well!
