starting old seeds question
 

I haven't been able to get here very often. Missed you guys.

Craig, I'm trying to start some old seeds from one of your gardenweb seed offers. I put them in some seed starting medium beginning of February after soaking for several days. Not one has popped up yet, much to my dismay. I've done fairly well with your old seeds as you know. I'm not really sure what I can do now. They need to get up and running soon if they are to stand a chance here. They have been on a heat mat, watered when necessary and there are lights overhead. The lights are there because flats of newer seeds are nearby and have already sprouted. I have a new greenhouse set-up, and we have been fortunate to have more sun recently. Have been thinking I would put the old seeds out there and see what happens. It can get mighty toasty in there on a sunny day.

Do you have any ideas? I was thinking it might be time to make some compost tea, or use dilute fert of some sort on them.

By the way, this is in response to your post asking newbies to ask a question or two. Not exactly a newbie, but here I am anyway. And anyone is certainly invited to respond if you have an idea or three. :D

Blast it all. Sorry I put this in the wrong place. Do I need to move it? Heck, I don't know how to do that anyway.

maryinpnw

Mary, you can't move it but I could but with this new system we have I can see where I can move posts but not threads.

So unless someone comes along and wants to move it to the Seed Starting Forum, lets leave it here for now.

You directed your questions to Craig. If you read in the Conversations Forum you'll see that his father died this past week following a stroke and he and his wife are currently in RI and I doubt he has time to answer you, so I'll try since I also offered many old seeds, as well you know and I think you were a participant in some of my seed offers of old seeds as well.

Those seeds of Craig must be quite old now since he hasn't made such an offer in several years.

What did you soak the seeds in and how old are the seeds, for he usually writes the seed age on the pack?

I know for some old seeds I've had to wait over two months and some never did germinate.:(

I usually keep the seed starting mix moist with the same solution I used to soak the seeds. Have you been doing that? And if any of them are heart shaped varieties, several of us have noticed that seed viability for them is not as great as with non-hearts.

[QUOTE] I know for some old seeds I've had to wait over two months and some never did germinate.:sad:[/QUOTE]

:shock: Two months! Wow, very interesting. I think I must have missed the time aspect in the old seed starting threads. I am curious as to what, physiologically or mechanically, is taking two months to happen. It can't be just dryness of the seed. After a certain period--months or a year--all seeds not kept over a dessicant will have come into equilibrium with the ambient moisture, i.e. they should all be the same whether a year old or ten years old, yes? Or is it that the seed coat becomes less permeable with time? Is the nitrate soak (I forget what actually it is) dissolving something off the seed coat or does it stimulate an enzyme somewhere inside the seed?

Pardon me for thinking out loud here.:oops: It's the end of a long, long week. I need some tomato seeding therapy.

Hi Carolyn!
 

Thanks for stepping into the breach Carolyn. I missed the news about Craig's dad. I'm sorry for his loss.

Seeds from early to mid-90s I'm pretty sure. I shot my wad and planted everything and put the envelopes through the shredder. Yes, I'm giving myself a slap for that trick. :oops: They were all from the USDA as far as I know and he did not supply any info about them. Maybe you or others have grown these successfully and can tell me about them.

I soaked one for three days in water, one in water with a tiny amount of milk, (just for the heck of it), one in weak tea. I think I might have tried some extra seeds in a weak Miracle Grow solution. Talk about a failing effort.

I have kept the seed starting medium moist, but not soggy. Have not tried watering with any other solution. Maybe I should try.

The good news is I have lots of other seeds produced in the last few years that started nicely, so I'll probably be begging people to take seedlings again, but I love growing the mystery seeds. Thanks for any advice.

Craig did a small, informal offer of "Branscomb" seeds to a few on GW in spring '06 (perhaps late '05). Maybe that's what Mary is working with. :?:

If so, they were pretty old seeds, sent to Craig in '90 by Don Branscomb. I can't find the original offer, but here's a thread alluding to it--

Thanks Suze!
 

Well shut my mouth. I don't save these threads. I'm too much of a packrat about some things and have to slap myself sometimes.

Thanks for providing this info. :)

Did not have any luck with these last year. Any suggestions welcome.

Mary, I don't recall very many folks even posting back on results, which tends to make me think most didn't have much luck with the seeds. They would be close to 20 years old, since they were given to Craig in '90.

What I would do is soak them overnight to 24 hours in warm water containing a pinch of fertilizer. Then I would sow them in a soilless seed starting mix, being careful not to get them either too shallow or too deep. I'd probably also get the heat mat out, even though I usually only use it for pepper seeds (alternatively, find a warm spot to set the flat). Be prepared to wait 3 or even 4 weeks before you see germination (if at all).

The Best method by far-for germinating old seeds, is the ziplock plastic baggie method.

I personaly have had tremendous results this year on old seed germination, the method is simple- just a sheet of kitchen roll paper, folded into half and then folded over again-well dampened with water and lightly squeezed out so the paper is very damp but not saturated,water with a touch of seaweed liquid feed in it helps.

Then place the seeds in the middle of the fold and put back in bag and seal. But -I personaly just lay them on top of the damp paper so that I can see through the plastic bag and tell which ones are sprouting more easily.

wait five days until you notice plenty of condensation and water droplets in the bag (which is kept at about 74 degrees F, ) and you should get germination within the next week to ten days, depending on the age of the seeds, this method really draws them out and forces them to sprout, I would say that the germination rate on old seeds is improved by 75 % and your chances are much better, once you have fished them out of the bag carefully and into some seed compost to finish sprouting -they pop up within three days.;) :arrow:

thanks to all
 

Since the seeds have been in seed starting medium since early February, I don't know if I can fish any of them out. Suze, I have watered them with some dilute fertilizer and put the flat out in my greenhouse.

Michael, I will have to try your method. I think it's a bit late to start anything now, but weather in western Oregon is always a gamble. Maybe I will hunt through my oldest seeds from Craig and Carolyn and start a few to see what happens.

Well -failing the fishing out of seeds out of the seed compost, the next very best thing you can do if they are in little seperate pots -just put the individual pots into a plastic food bag and screw the bottom round to seal it so that the top skin is fairly tight accross the top, after one day heavy condensation will form on the top skin , its the same with seed trays-all you can do is tightly wrap them in saren wrap, or place the whole thing into a large clear plastic bag the same size as the seed tray and seal the end with an elastic band or tie,

Those two methods work nearly as good, and will quickly aid germination even up to the three week stage after the plastic bags have been put on.:arrow:

I have had lots of luck with random seeds germinating in my vermicompost bin- im going to try to start some old eggplant seeds and my one no-show tomato that I still have seeds for in Pro Mix and Vermicompost mixed.

Mary, I apologize for not following up on this thread. I guess it went to the next page and I forgot about it.

I know Patrina and Michael like the zip lock baggie deal but when I've tried it I tend to get lots of mold when working with old seeds b'c so often one has to wait from one to two months before anything germinates, if indeed it does.

And that's why I use the method I do, which I think I outlined above.

Tell me what old seeds you have of mine and I'll tell you if I have more recent versions of them.

And of course you can always have more OLD seeds, I guess, of most of the ones you got in those seed offers I made several years ago at GW.:)

thanks to all
 

Hi Carolyn,

No problem. You've got a lot of people who want your expertise.

I'd have to go back to my seed drawers to see what I have from you. I'm not growing any of your old seeds this year. What I really need is about 5 acres to grow everything I want to, but that isn't going to happen. Oh well. I don't see an ironic emoticon smilie. That's what I would put here now.

At this point, it might not hurt to try what a Michael is suggesting. I just hate to give up.

I'll let everyone know how it goes.

maryinpnw

it's a no go so far
 

Well, I have been keeping the seeds warm and watered, but so far, nothing has popped out of the seed starting mix. I'll keep at it for a while.
