Packet seed shelf life?
« on: March 26, 2020, 04:36:37 pm »
Anyone have experience of using 'out of date' seed from those packets of commercial seeds.  e.g. Moneymaker tomato seed from 2014   :)

Is it a case of may germinate, but not optimally..?

Pretty well, yes.
What have you got to lose? Give them a go, but don't expect stunning results.

A lot will depend on how you stored them, but as SteveC says, give it a try, why not.

Thanks.

Planted tomatoes, parsely, and two types of chilli, in covered indoor germinating trays, so will see what happens...

ETA. and mustard & cress.  All out of date.

I think it varies massively but crop. IIRC parsnip don't last very well but some do better. If you can I think they recommended putting some on damp kitchen roll and seeing if anything happens

yes, parsnip in particular need to be fairly fresh, >2 years and it's pretty poor germination

I bought quite a lot of new seed this year and have >90% so far.

Cool.


Next time grow something tastier than Moneymaker - they've got to be the worst of the ones you can grow yourself - in my opinion  ;)

Out of my 2007 seeds I have Cherry and Moneymaker toms plus chilli and leeks germinated from a soaked kitchen paper test of 10 seeds of each. 

No shows were the Broccoli Beetroot, Cabbage, sprouts and peppers.

3 year old french bean - 20% germination
this year's runner bean - 90% germination

The only older seed I've had good success with this year is red chard

Both chilli and parsley benefit from warmth - if you have an airing cupboard it’s good place to start them. Chilli in particular can benefit from putting in a plastic bag too.

Came here to ask about seeds too.

Have tried soaking the seed is peroxide https://balconygardenweb.com/soaking-seeds-in-hydrogen-peroxide-germination/ still failed as i left the seeds in peroxide for too long.

Well I sowed some seeds yesterday. One packet had an expiry of 2017 and the rest were all 2011/2012. Perpetual spinach, spring onion, cayenne pepper, bell pepper, tomato and butternut squash sown and in the patio window.

Not expecting a great deal but nothing to lose if they don't germinate. It's not like I can get to B&Q at the moment anyway.

Though I have just now remembered that our little Tesco have got a little seed stand at the moment. Could pick up a couple packets when we next shop.

Found some seeds that were over 10 years out of date.

Trying to see if they germinate by leaving them on a wet kitchen towel in a plastic bag.

I tried some more 4-6 yrso seeds including chillis, squash, melon, basil - nothing, not one. 

I now have 10 large tomato plants (2014 seeds) and around 20 getting bigger; itching to get ouside.  Will probably plant out 5-7, swap some with the neighbour for other veg plants (they have allotment), and the rest will go ouside for passersby pickup...

After the wet towel I have quite a few basil seedlings and all 6 courgette seeds have sprouted.

So potted them today in to poundshop multipurpose compost and lets see what comes up.

Dez was clearing out the shed and found a load of parsnip seeds, best before 2009. I sprinkled them liberally around the place, but I doubt that we will get any parsnips rom them.

Parsnips are one of those I would never try and use after the first year

Agreed. Even fresh parsnip seed is not great at germination.

Got a few packets of new seed in.  So far, going to try...

Tomato:
San Marzano 2 - apparently good for sauces.   Possibly with a few moneymaker again, from this year.

Chilli:
F1 Longhorn - high yield / less heat
Chocolate Habanero -  heat

Parsley & coriander.

If I can convert the area where we had a large trampoline to beds, & tree surgeon to get more light in, may expand the vegs grown...
