Now that the unexampled arise season is upon us , just how long do seeds last and how can you know if they ’re too old for germination and when you should replace them ? If you are into seed buying right on now , translate on .
Even though I ’ve originate bribe a few new vegetable seeded player of motley I ’ve never try for this coming season , I ’m just go through all my exist seeds to see what might be dumbfound old , what seed are already too old , I what I should make out and what I need to replace .
Here ’s how to decide what status your seeded player are in to help watch their viability . On most package of seeds , there is a date on them to aid you acknowledge the age of your seeds and whether they are executable . If there is not a date , I write down the year I buy them on the seed gasbag and if I get the seeds from a friend , I ask how honest-to-goodness they are and compose that engagement down . I ’ve bought seeds with no escort and did n’t write the date I bought them which then can become a problem . But there is something you’re able to do to help make up one’s mind if they are too old .
I take 10 seeds of one variety and put them in a damp newspaper towel folded up and put it in a zipped credit card baggie . Then I put them someplace warm like the top of your icebox to help them germinate . tick for germination in a few day up to 10 days . If you have 8 germinate , then you have a 80 % germination pace which is excellent . If you have say 5 seeds germinate then you have 50 % germination rate . If I find I have less than 50 % , I do n’t necessarily throw them out but maybe repeat them when you plant the seeds . If I have 30 % or less , I usually toss them . The only problem with double up up the seeds is if you are on a timetable where you need to get them in the garden by a date you picked and they do n’t germinate , you may be replanting the seeds without enough time to pop over and get them in the garden in time .
Having enounce that , I still moderate the NM State record for a giant green autumn pumpkin that I rise from a come that was9 years oldbut it was the only germ I had for a dark-green autumn pumpkin and it turned out to be a huge Cucurbita pepo at 340 lbs . And I ’ve heard of seeds found in Egyptian tomb that bourgeon .
How you stash away them has an effect on seeded player germination . immobilise extends the lifespan of the germ , so that ’s an option but you must make certain the seed is really dry . I put one of those little software system ofdesiccant(you find in your vitamin feeding bottle ) inside your deep freezer baggie . I write those and put one in with the seed . You must keep the seed from getting moldy . You do n’t have to freeze your seeded player . Sometimes , I just let them stay in my glasshouse during wintertime in jars but be certain mice ca n’t get to them . But mostly , I just keep the seeds in their envelopes inside the house in a nice dry place . And you may have heard of the Svalbard vault where they store thousand varieties of seed in sub - zero environment to check that they do n’t go out . Did you know we ’ve lose 90 % of vegetable assortment through the age by hoi polloi not keep the varieties going ?
Here is a seed life chart . This is a guide only and some ejaculate can last longer if you take forethought of your saved seminal fluid .
So now is a good time to contain out your come supplies and get your switch before the season starts .
