If you ’re like me , hive away germ is a essential . You may have particular flowers that you grow every class like geranium , or a favorite kind of kale or Citrullus vulgaris that you love the gustatory modality of . But knowing how to store seeds is incredibly significant , as poorly - stored seed wo n’t germinate .
No matter if the seeds are large or little , these seed storage tips will aid you keep your seeds workable for long periods of clip . Even if you just take them to be viable until the next planting time of year , it ’s significant to have the right conditions in place !
So if you find that uncommon semen type you ’ve been look for at long last , go before and catch a package or two , and I ’ll go over the good way to save and lay in seeds for long term use !

Learn How To Store Seeds For Years
Those of us who are willing to collect and stock seeds year after year have a slight advantage . We do n’t need to look at years down the credit line , only how to get us as far as the next planting time of year .
Seed Saving: The First Step
Whether you ’re seek to make up one’s mind how to store vegetable seed or how to store flower seeds for next yr , the mental process is nearly the same . First , you have to save seeds . let the plant ’s seeds to senesce as they normally would , then start pull in source !
Once you take in seeds , if there is a gel ( such as in tomatoes ) , you ’ll need to murder that gelatin . It is an contribute generator of food for the source , but it does n’t help while keep the seeds .
To polish off this colloidal gel , place your gel - cake seeds in a trough of water with a hat . Once per day , shake them up or stir them . The colloidal gel will pause down and come off the seed , and you could then rinse them off wholly .
Drying & Storing Seeds
Once your seeded player are marginal , it ’s fourth dimension to dry them . Ideal drying temperatures are between 60 and 100 ° F ( 16 and 38 ° C ) , and your seeds should be spread out in a slight layer on a art object of lambskin paper . position them in a well - ventilated place . bring up them every day or two to ensure that they dry evenly .
If you have a food dehydrator that has extremely low - temperature preferences ( 80 - 90 ° degree Fahrenheit or 27 - 32 ° C ) , you may use this to help dry out your seeds . However , do not run it for more than a half hour at a metre to prevent unintentionally cook your seeds . If your dehydrator run hotter than that , do n’t use it !
A sports fan can assist ! Place your seeds between two ok - meshed screen ( I utilise line conditioning filter ) , and use bungee cord cords to secure the filters to the front of a box sports fan . Prop your lover on a duo of bricks to allow air to make out through the fan from underneath , and turn it on .
belittled seeds should dry via forced airflow from a sports fan in 24 - 48 hours . Large germ like pumpkin ejaculate demand much more time , 7 - 10 days or so .
Once dry , place your seeds into a storage container . This can be paper envelopes inside a Mason jar , a seed storage corner , even zip - closure bag with all the zephyr compress out . indite the type and date on your packets !
Place your seeds in a cool , dark location . 60 - 65 ° F ( 16 - 18 ° C ) should be fine for collecting seeds for a year .
How To Store Them Properly For The Long Term
What if you ’ve got a large seed collection , or are looking to swap out variety every other twelvemonth or so ? mayhap you ’re being proactive and saving seed for selection purposes ? The best way to stash away seeds foresightful - full term is to make the pure conditions for your seeds to lie in in .
The arcanum is in two words : cool and dry .
Ideally , there should be no wet around your seeds . The temperature should be 40 ° Fahrenheit ( 4 ° Celsius ) or lower , but should not drop into sub - freezing temperature as that kills some forms of plant embryo . It should be non-white or dim , and it should be pest and critter free .
Consider Cold Storage
I urge using a cold storage option such as a beverage cooler for your ejaculate storage . It ’s compact and can be insert into modest spaces easily . Consider getting one with full temperature control so you may set it to your best-loved frisson floor .
While you may hide cum in the back of your icebox , you ’re in all probability going to need to keep your seeds cool than your food is . Many the great unwashed stack away seeds at or around 35 - 40 ° F ( 2 - 4 ° nose candy ) , and the lower end of that shell may have frost legal injury to your solid food .
Having a disjoined , temperature - controlled placement for your seeds is a really good theme . Not only can you optimise for the best prospicient - term source storage , but you wo n’t let the cold out multiple times a day when you launch the door for solid food .
Avoid Moisture
A tank surround will make moisture to condense more readily . You will want a fully seal container to keep that moisture out . instead , you may sum moisture - absorbing parcel or fully dried Sir Tim Rice grains to your warehousing corner to keep humidity at bay .
Plastic bagful are not the enemy in this type of storage , but you have to be super thrifty that no wet is trammel inside the bag when you seal it . Press out all airwave if possible , and verify it ’s whole unsympathetic so wet does n’t get indoors .
Temperature & Light Conditions
Maintain the temperature at your optimum mountain range . It ’s hunky-dory if you have to spread your cooler every so often to put in or remove seed , but if there ’s too much fluctuation , it can become a trouble . I recommend aiming for 35 - 40 ° F ( 2 - 4 ° degree centigrade ) as the ideal temperature .
If you could , put your seeds into an unintelligible parcel or inside an unintelligible boxwood . This lend another bed of light prevention , although the temperature and humidness are the key factors in moth-eaten storage like this .
Taking Your Seeds Out Of Cold Storage
When removing your come from dusty storage , take the box seat or container they ’re in out and do not now afford it . Instead , set the container somewhere and walk away until it has reached ambient elbow room temperature .
Rapid temperature changes wo n’t shock your seeds , but a quick temporary worker modification can cause moisture to condense inside your container , and it can be difficult to take out before you put your semen away again . let it warm up up naturally avoids this publication .
For this cause , I recommend you organize your seeds in boxes based on the planting time of year . After all , if you to get ready to set in February , there ’s no tip in starting seeds slated for July or August , and they can continue to stay stored away .
Dry Storage
All the conditions needed to stack away seeds in a wry location are the same as they would be for cold computer memory — minus temperature . Keep moisture out of your germ packets , and control they are n’t expose to light . This keep them dormant while you ’re waiting to plant them .
ironic storage can be in any location that meets this canonical criteria . A cabinet , drawer , or shelf are all appropriate places for your seeds . you’re able to stack away them in their packets . you’re able to also impart an spare layer of protection by store the mail boat in jolt , portfolio , or even in photo box .
Jacques and Kevin of late acquired an old card catalog to store the monumental amounts of seminal fluid they have . Card catalogs are easy to notice 2nd - hand , and they ’re great for multitude who have an ever - growing seed assemblage . They offer the ripe luminousness and moisture controls for put in source .
picture box tend to be the preferred method acting of warehousing for many gardeners as they hold up over clip and organize seeds in a pleasing way . you may find absolved , opaque , or translucent edition of picture boxes in art store , and online easy .
How Long Are Seeds Good For?
This is a tricky question , and it really depends on what eccentric of seeds you ’re stash away as well as the conditions that they ’re salt away in .
Most annual flower seeds are workable for 1 - 3 years in optimal cold computer storage conditions without pregnant debasement . perennial can go a fleck longer , from 2 - 4 yr .
How long do veggie seed last ? That ’s more difficult to establish , and it may have to do with natural oils in the seed . The oilier the source , the more likely that the oil colour will spoil , and your seed will fail .
Approximate Storage Times
edible corn , spinach , parsnips , and alliums such as chives or garlic seem to have the shortest seed aliveness . These tend to have higher oil content than other vegetable types , and you should aim at replacing these case every twelvemonth .
Every two geezerhood , you should replace your onion or leek seeds , bush or rod edible bean , white pepper , beets , Petroselinum crispum , and Swiss chard .
Three year ? That ’s when you must replace your lettuce , melons , carrots , squash , tomato , cucumber , rutabagas , and Asiatic greens such as mizuna or bok choy .
Radish seed and turnip seed can last up to four years . Brassicas such as Brassica oleracea italica , Brassica oleracea , turnip cabbage , Brussels bourgeon , and Brassica oleracea botrytis tend to last 4 - 5 years , as do kail and collards .
What About Longer Storage?
These number are all estimates for the “ upright by ” escort . Much like food , seminal fluid do n’t right away go bad once they ’ve passed that engagement . Their germination degree just slowly proceed to drop , making it far less likely for them to produce a goodish live plant .
There are reports of people successfully germinating seeds that are decades previous , even 80 years later . The subsequent plant has to be very carefully cared for , as it will be ab initio quite weak . But it is potential ! It ’s just more and more improbable as time goes on .
I would not keep any seed for more than 10 twelvemonth at a time if I need them to remain viable . Even then , 5 years is a unspoiled maximum chain of mountains .
Seeds in the Freezer: Good Or Bad?
Should you freeze seeds ? I incline towards “ no ” overall .
For most , immobilize is a risky proposition . Your deep-freeze needs to be able to assert a constant temperature of -20 to -15 . Most of us open up our freezers far too on a regular basis to keep them cold enough to keep cum bear on .
Residential freezer also are n’t as cold , chilling to -10 to 0 degrees Fahrenheit . Now , if you desire to buy a chest Deepfreeze that can pass on -15 to -20 temps and freeze out seeds , they subsist , but again … what if the power goes out at an inopportune clip and your seeds start to warming ?
This is not to say that freeze is always a bad idea . Seed repositing banks do it !
But seed entrepot banks typically flash - block their cum to chill them very rapidly . They also use large deep freezer that are open at most twice a year , and have huge backup generator . At home , we do n’t have those option pronto uncommitted .
In the end , no matter what zombi Revelation of Saint John the Divine or public war we require to be prepare for , a freezer wo n’t help . Once the power lead out , your moth-eaten reposition ends , and you are back to square one . It ’s best to store smaller quantities of your favorites for unretentive periods of time .
Seed Storage Containers & Supplies
There are a few options for seed warehousing containment that I ’d definitely recommend !
I personally like to store my seeds in coin envelope . These newspaper publisher envelopes are a beneficial sizing to fit into an airtight boxful . If you want to be doubly good , you’re able to use a ironical corner with moisture - bar seals to keep moisture at bay .
If using paper envelopes , you ’ll desire some form of desiccant to reduce moisture as much as possible . There are two options : you could use dry white rice to absorb wet , or you could opt for a silica gel packet .
Do you have a vacuum sealer in the household ? If you do , conceive mylar bags . you’re able to vacuum - varnish these and keep your seed free from damp air . Larger mylar bags are usable if you purchase seed by the pound formicrogreens !
What if you ’ve got a lot of tiny seeds and do n’t desire to hoodwink parcel ? Consider a multiple - chambered storage box like a pic storage box . Each intragroup box holds multiple packets of seeds , and the seeds will persist neatly separated and organized .
Any of these options can be direct inside cold storage , allow you to reduce the temperature around your germ to make it less likely they ’ll attempt to germinate in their packets . And the better your seed are protect , the longer they ’ll last .
What Causes Seed Degradation?
Like all organic material , seeds will break down over meter .
Most of us learn in grade school about the various piece of a source . As a refresher , there are three major parts . The seed coat is the external hard carapace of the seed . Inside , there is the plant ’s conceptus , along with what ’s called the endosperm – a source of food to sustain the embryotic flora .
The flora is dormant while hidden within its unvoiced external shell if stored properly . In the incorrect environs , the plant life is going to have a hard time “ staying gone ” and may start up trying to develop .
Keeping the plant dormant is significant , but even if it is , the endosperm will gradually break down , just like any other food product . It is preponderantly made of starches , and those last for quite a while , but even they degrade in time .
In summation , some seed are oil colour - robust , and the oil can botch as well . Most often , these are the seed with the shortest lifespan .
There are other factors which will accelerate up this degradation . Let ’s examine these in a bit more particular !
Light
Sunlight is the enemy when storing many organic products . This is doubly on-key for seeds because the luminosity stimulates the tiny flora inside the seed . As plants feed on sunlight just as much as they do on the grease , a weak source encourages them to essay to sprout .
Therefore , it ’s essential that you keep your seeds in the dark as much as possible . Opaque container help quite a lot , but if you do n’t have opaque containers , seeds can be stored in a dark environment to foreclose as much light exposure as you could avoid .
Moisture
dirt is more than just a reservoir of nutriment for a plant . It ’s also what keeps body of water right at the root of the plant so the plant ’s able to get a drunkenness .
It should n’t come as a surprisal that wet can also goad sprouting . After all , when a seed is below the soil ’s surface , brightness level may not penetrate that far , but the wet will . That ’s great if you ’re stress to grow Medicago sativa sprout , but not so good when you ’re trying to stash away seeds !
Moisture can cause the kayoed seed paries to soften , which also opens the cum up to the peril of rot . This is the enemy when you ’re adjudicate to promote in force quiescency . nullify it as much as potential .
Temperature
Along with moisture , dirt temperature come as a signaling to a seed that it ’s germination fourth dimension . However , your cum does n’t know the difference between being planted in good potting stain and being stored inside a paper envelope .
Since most plant germinate at temperature above 60 degrees Fahrenheit , preserve them in atmospheric condition below that should prevent your cum from sprouting .
If it ’s warm enough that the plant will normally bourgeon , you ’re running the hazard of your carry on seed not stay abeyant . And in non - dormant conditions , they will take down more quickly .
Pests
Have you ever check a squirrel with an acorn ? If so , you know that cuss do go after seeds , and there ’s a long list . It ’s not limited to just gnawer like mice , chipmunk , squirrels , or rats . Many louse also ingest seeds , and of course , so do larger animate being .
It should go without pronounce that you take to be proactive . Use some phase of pest - proof containers . If they ’re moisture and pest - proof , that ’s even adept .
