- Cold stratifying seeds is simple and easy, but many gardeners fail to do it. This episode covers how to do it, what cold stratification is, which plants need it, and which ones don’t need it.
St. Johns, Artichoke, Strawberry, Mary Washington Asperigus, Catnip, Marshmellow, Thistle, Lemon Balm, Lavender, fruit trees, perrinials. 2-3 weeks in fridge. Thanks so much. Been a lavender issue for me.
No wonder I could not get lavender to grow! I did not put them in the freezer!
@@hopeking3588 same here
Thx for the list. I was short on time today so your list helped me skip watching. Thx again!
I keep a list and hope you will too...
24 hours in the freezer is all you need ...
I tried cold stratifying lavender both in the fridge and in the freezer last year and had success with both methods!
I did not know strawberries needed it though! That explains my 0% germination of my wild strawberries in my basement haha. They were a different company's seed though and a few years old.
I wish all seed companies would put "NEEDS COLD STRATIFICATION!!" in big bold letters on the package since it's so important for germination!!
Does the freezer method work faster?
@@rhyothemisprinceps1617 I don't remember if they germinated faster but they appeared to get enough of the cold stratification
I just go to the frozen fruit section of the grocery store and I buy the mixed bag of fruit with blackberries strawberries raspberries just throw the berries on the surface of my planter and I sprinkle dirt on top of it and leave it out over winter and in the spring I had almost every seed sprout. So if you want to skip that stratification and freezing just buy them already frozen fresh fruit.
@@zeldasmith1088 that's a great idea! And if you wanted a particular local variety, just buy a few extra when they're in season, and freeze the leftovers to do that with them the following season
@@FloraM44 I've started kiwis and mango and I just started 3 big pots with 2 kinds of blueberries,2 kinds of blackberries, and 2 kinds of raspberries and 5 small pots of lavender seeds. The frozen berries I planted last year all came up so this yr they will be 2. Hope you all have a wonderful gardening season 💯
No wonder I haven't been able to grow strawberries from seed, learn something new everyday!
I tried growing lavender from seed for 3 years. Nothing. Then I saw an older video of yours talking about cold stratification. I ordered lavender seeds from you and did the cold stratification and had over 90% germination which I'd heard was very high for lavender.
It’s amazing the difference it makes. Glad it helped!
I went through 3 packs of MI Gardner lavender seeds before I learned from his older video as well. I winter sowed them this year in milk jugs and got at least 90% also.. 😂
@@MIgardener but why is this information not on your seed packets? It's disappointing.
@@PreciousPatchesFarms, my lavender seeds from MIGardener says must be cold stratified.
This puzzles me a bit... I mean: why should seeds need a refrigerator and can't make it just on their own outside? I'm sure this method is science-backed and it really works but it still seems strange. 🤔
I would also like to see a list of seeds that shouldn't be dried out before planting such as citrus. You deserve to have a million subscribers! You have great videos!
I am on my 2nd year of planting a garden with my son. Watching your videos has been a blessing. I had NO knowledge of planting what so ever but our very first garden was a big success because of your videos. We had tomatoes as big as our hands. We had tried tomatoes a few times before and failed. We are in our second year for asparagus and can’t wait til a year more so maybe can eat some.
Thank you for giving us this opportunity to teach our 17 year old about gardening. He loves it.
People are really going to need to know how to garden with the supply chain situation going on. Canning supplies are already being purchased. Appreciate your channel.
Hey Luke! I've been waiting a while to catch a video within the first hour I just want to say thankyou so much for inspiring me and many more people to get into gardening. Congrats on the soon awaited million subscribers. Oh also thanks for the extra seeds! 👍😁
Thanks for your support! Happy gardening :)
Thank you, Luke! You are the first to tell me why I have never been successful at growing some plants from seed. I’m Sixty years old!😁
I just threw a bunch of perennial seeds in the ground last October before the freeze and prayed. We'll see what happens!
Did it work??????
How did it go?
Luke if some seeds need the cold to germinate, why would they leave that information out on the seed packet?
Shouldn't that be part of the information on the seed packets?
Because mabey they don't know,or the NWO wants us to stave!
I bought some seeds of etsy and it said it on mines. But u are right, they should all say it
Important step you forgot to mention: label the bags with marker or something so you don't forget which seeds are which. 😅
You don’t have photographic memory? 😜
“Oh I’ll remember what that is” I get side tracked and have no idea what seeds I started.😳
Came for the Cold fusion...stayed for The Cold Stratification
Thank you for this video! I only learned about Cold Stratification: today! Now I have to push a handful of things back a few weeks, but I would rather do that than be disappointed with poor germination rates.
I'm 1 in a million!....
Congrats on your channel's success!
Have never in 45 years of gardening heard about this so I'm all ears, will share with some others for new subs!
Thanks for your support! 🥰
Well, like I've always said, don't plant anything without watching MIgardener's videos!! I bought lavender and had no idea I had to use the cold stratification method for them!!! A gazillion thanks, Luke!!❤
Luke, you deserve every sub, and then some. I appreciate what you do. Thank you!
Awe thanks William!
Learn something new every day. That's what I love about gardening. I've been gardening since I was able to walk. Never knew about cold stratification. Probably because I've always had a tiny yard to grow in so I've always stuck with the basics. But we just bought 25 acres and can't wait to try growing so many new things. Thanks for the information
MIlkweed (non-invasive) also appreciates stratification. Last year - I germinated so much I had to give away. I have not had any luck with germinating lavender in my area (5a/b); this year I am trying Munstead which is supposed to be more cold hardy. We'll see. This is great - shows how easy it is. Thank you!
Thanks for the tips! I would add - make sure to label your bags so you know what the seeds are!
I was just searching for tips on this very topic last night. Synchronicity at its best
I generally start cold stratifying my peach and apricot seeds right after Christmas in my fridge in butter tubs and pull and pot them around Valentine’s Day. I try to do about 10-20 of each variety every year. I keep them for about a year then keep the best couple to plant and sell the rest.
I was literally searching the web for exactly this info about raspberries but couldn't find how long to keep them in the fridge! Thanks Luke!
Thank you so much for sharing your gardening wisdom. I never knew this trick. You are a great detail oriented teacher, that is why your channel has grown so much! You are the best!
Hey, your products and apps are awesome! The best place to shop. I just had to say that.
I've never commented on your videos... I've enjoyed your content for several years now--I've been impressed at how much you know about gardening at a young age.
My experience with cold stratification -- we've done this for decades -- the freezer. The 2-3 weeks can be extended. Mold is not an issue.
Thank you again. You do a great job.
Hey bro can we do this seed startification in monsoon ??
CAN YOU COLD STRATIFY STRAWBERRY SEEDS IN THE FREEZER? HAVE YOU EVER TRIED IT? THANKS.
Thank goodness for this video! Such a simple method.
I’m so glad your channel was suggested to me! We’re here in Michigan too and I need all the gardening tips I can get.
Yayo! Let's go 1M. Well deserved for one of the best educational gardening videos out there. MIGardener shop is also the bomb.
Thanks for posting about this topic! This explains why my lemon balm and lavender did not germinate last year. I was in a rush and did not read the seed packet carefully.
That will do it. Give this a shot and then watch the magic happen. Good luck!
I am using the winter sowing method for seeds that need cold stratification this year but I like learning about other methods as well so thank you!
I get some good germination by doing the same but putting lavender in the freezer for 3-4 days. Probably not as good germination as yours but in a pinch it will work.
I finally subscribed since I watch you so much and have learned from you. I live at 8,000ft in Colorado and been gardening for 40 years here. Still things to learn. At point of starting seeds needing this and looking how others are doing it. Thanks.
Hi Luke,
I'm wondering why your seed packets don't tell us to cold stratify these seeds? I'm certain we would have much greater success and germination rates if that was added.
Hope you add a sticker in the future.
Thanks! Kate
My lavender seed packet from MIGardener says to cold stratify.
@@ginnysummers7018 good to know! My Asparagus doesn't. I have to look at my other seeds
We appreciate all your garden wisdom, Luke! Thanks to you and your family!
Perfect timing! I just bought some of those seeds yesterday! Thanks Luke!
Thank you for the lavadaur tip, now I will try this again.
Another incredible TH-cam video!! I was always wondering what this cold stratification thing was about! Thank you so much for making such inormative videos for! Always a pleasure ☺️
Congratulations on all of the viewers!
Thanks to amazing people like you.
Yeah, tomatoes, eggplants, peppers and chillis do not require cold stratification.. Really helpful video on cold stratification 👍
Thanks Zach! :)
Just planted those Giant crimson tomato seeds I got from you! Super excited to see what comes of them
Got my seeds from MIgardner. Excited about my gardening season!
Thank you so much for this video, you saved my seeds! Please continue the work you do, it's inspiring.
Don't forget to label the bags!
Thanks for the lesson!
🌱❤👍❤🌱
I am so glad you did this video! It will help me out a lot for the MiGardener seeds I purchased. Also caught the video you did yesterday. All this is good for zone 6 garden 😀. Thanks Luke, you are the best!
Perfect timing!! I was just about to google how to cold stratify lavender!!! Thank you!!!
Wow, I have half of those so I'm so glad to know! Awesome info Luke! Will be my first year doing this . I now know the reason for years not coming up!
I don't use your seeds as I'm in Australia, but now I know why I've had trouble with some seeds.
Mallow and Lavendar in particular - the packs don't mention it. I have grown lemon balm without - guess I got lucky :)
Great information 👍👍
Great video Luke. Thank you for sharing your knowledge. Gotta go cold stratify now!!
First time growing celery. I’m experimenting with two methods of cold stratification. I had put one batch of seeds in a little zip lock bag in fridge based on another TH-cam channel instruction, and then I watched your paper towel method on one of your celery specific videos….so I “damp” cold stratified several celery seeds…just got both seed groups in seed starting trays…. Kind of a little experiment 😆
Gonna use your method for lavender next. Thanks for your videos and instruction….congrats on your almost 1 million 🎊
If that doesn't work, try freezing them overnight in the baggie, then a day in the fridge, then a few days in the window or under lights. I got seedlings in 2 weeks this way.
Update: The seeds in the damp paper towel stratification group started germinating in about 6 days and look healthy (and adorable 😆). Still waiting for the just seeds in the fridge group. (Both groups had been placed in fridge for about 4 weeks).
Such valuable information. Thank you, Luke, for all you do! I REALLY appreciate all the time and effort you put into your videos. Wishing you great success!
Thanks Luke😁👍❤🙏
Luke you deserve 1 million! Ty for sharing your knowledge with us! I did use stratification with my fridge weeks ago. Next year do video early because in my zone and yours to be honest this is late
Ah, this explains so many things!! Thank you.
WOWZA!!!!!!! 1 MILLION YOU SO DESERVE IT ,THANKYOU 💖
Thank you!
Your video was so helpful thanks! I have a few questions.
I am just a bit unsure - after 2-3 weeks plant seeds- in ground or inside? In potting mix?
Do I have to see if they have sprouted or just seeds?
Off the paper towel? Last time I tried I couldn't get them off without damaging. Thanks for your help😊
Winter sowing is much more easier. I love it
Gracias por enseñando y compartir tanta sabiduría que llevas y nos las enseña con tanto amor y muy clara. Dios te bendiga y guíe tu camino.Un abrazo fuerte desde Puerto Rico. Las semillas de Rosas y otras flore que tiene semillas diminutas se puede usar esa Método de Estratificación.Gracias!!!!
Gracia Lucas .
I forgot to do this to my lavender I started today. I’ll do some with the leftover seeds and see which one turns out lol.
hay Luke great video I was wanting to cold Stratify some perennial seeds for my garden this year but I found out I am to late I guess I am going to wait util next season
Could you do a video on all the garden veggies that are perennial for your northern climate? I saw the one where you said blue curled scotch kale is perennial and was wondering what else is?
Oooooooooo!!!! Thank you for this Luke!!! I harvested a binch of columbine seeds today and i also have lavender, and a fea other seeds that woll need cold stratification before planting. Im so excited to try this ❤❤❤❤❤
Not that surprising..your personable and extremely knowledgeable... You've earned it..enjoy the roll
I've never had any luck with the paper towel method. They always mold or don't sprout. I'm trying the cold sewing method with those types of plants this year
Well this explains why I can never get lavender to germinate LOL!!! thank you
Como pasar las semillas ya germinaba en el tiesto. Como hacerlo. Gracias Lucas 👏👏👏👏👏👏👏👏👏👏👏👏 Eres genial Lucas 👏👏👏🙏
Thank you for showing us how to cold stratify! I have a bunch of perennial flower seeds I am trying your method with this year.
Do you have recommendations on how to transfer the seeds from the wet paper towels into the growing medium? Is there a way to do this that allows the seeds to sprout before being transferred? (So less thinning later on is needed?
Thank you! This was so informative. I will try it with celery and artichokes!
I would not add water to the baggies, especially if one is going to leave the seeds in the fridge until next growing season. I believe it is ok to keep the seeds in the fridge too: like poppy seeds.
I purchased a bunch of your seeds today MI gardener… I normally only purchase through Johnny seeds or bakers creek your prices are phenomenal and reviews really looking forward to planting some of these seeds this year
Hey Luke! On the back of my MIGardner Alexandria Strawberry 🍓🍓seed packet its stated to start indoors, cold stratify 5-7 weeks before last frost. Am I supposed to cold stratify these for 5-7 weeks then? Or do I stratify for 2 weeks and then plant indoors 5-7 weeks before last frost. Thanks for all your help and time spent with your videos! Much appreciated 💯💯👊👊
@12:00 he says add 2-3 weeks (for cold stratification) before the 5-7 weeks on the packet
@@JamieR2077 Thanks for your reply. I did notice that in the video but wasnt sure if the 2 weeks was already added to the 5-7 weeks on the packet. Its confusing with the way its worded on the packet
Watching video a day after planting asparagus in trays with greenhouse covers and putting under lights. Now they are all outside in the cold hoping that will do it!!
Super helpful
It's easier to just buy fresh frozen fruit that way it's already been frozen and stratified for you and you can sprinkle it on your soil and lightly cover w/ soil and let the weather in spring handle the rest.
that’s what i’m trying to do, does this work?? did it work for you?
@@cheesehead9980 yes
I grew for the first time marshmallow and milk thistle last year without stratification and they did very well. I didn't know they needed to be stratified
My Artichoke seeds germinate at room temperature. However, I will expose Artichoke seedlings to cooler temperatures to trick them into blooming the first year. I have had volunteer Artichokes as well. I like Lemon Balm, although I wish it was a cold hardy perrenial like standard mint. In that regard it is a whimp like Rosemary.
I live in zone 5B, and have Lemon Balm coming up year after year in my raised bed.
Huh.
@@rdred8693 I am in 7a/7b and it doesn't matter in ground , or pot and it's dead . The Winter Savory in ground and standard Mints in pots always come back. So you are lucky, or maybe you have a well adjusted variety.
I have to dig out lemon balm and oregano every year. They don’t die, it self seeds, grows and spreads everywhere just as bad as mint family. Zone 8b Western Washington.
@@robinwhitlatch4497 I am in 7a/7b it can get below Zero here. This winter 10F to 20F was the average at night.
@@kjrchannel1480 it gets cold here to. Must be the varieties. Also had a rosemary that lived 15 years, was pretty big and it died this winter. My oregano and lemon balm have survived 3 feet of snow, below zero temp and still comes back and spreads every year so I keep digging it out. Really wish most of the oregano would die off but nooo. Maybe I should send you some of my oregano and LB I dig out and see if it survives your winter. 🤣
Great information! I'm working on trying to propagate my white bleeding hearts, I didn't cold stratify them and should have. Don't forget to label the bag with what the seeds are. I might even put the seed packet inside another smaller zip lock bag and stick it inside with the seeds.
Well, thank you as well!
Thank you! This is such a helpful video!
So glad you enjoyed it! Happy gardening!
Hope the lavander and strawberries I did this year germinate. God bless!
I love how you broke this down into simple, doable steps that anyone can do. After watching this, I think I will try my hand at starting strawberries from seed. Thank you :)
We heard to put seeds in the fridge and others said freezer, good to know which is a better method. Thanks Luke
I prefer the fridge honestly. The freezer is a bit overkill.
My Blankity-blank is growing nicely this year!
Oh goodness, perfect timing. Thank you so much.
Very very helpful! Thank you!
Thanks Luke, this has really helped me out. 👍😊🤦♀️
I love your videos! Thanks for all the great information! I agree with some of the other commenters that all seed packs should specify if it needs to be cold stratified, but I have only just begun ordering seeds from you, so I don't have personal experience whether your packages state this or not.
Do you have to moisten them? I have just thrown my seed packets in the fridge.
Look forward to seeing you guys.
Excellent
Great video! I store all of my seeds in the fridge, it doesn't matter what they are lol Just out of habit 😂
Congrats on the sub numbers, you deserve it
Great info. Now I know why my lavender did not germinate last year.
First of all CONGRATS on your channel. I am new to gardening. I understand now about "cold stratification" for my perennials. My question is this: I have ordered Honeysuckle seeds. I live in Zone 8b 2 weeks in the "fridge" it will be mid May before I will be able to plant the seeds. Is it to late for planting Honeysuckle for this year (2024) or will mid May still be okay?
I would imagine spinach would appreciate a cold stratification aswell. I hed great success not stratified lemon balm so you mentioning that one surprised me. 👍👍🇨🇦
Me too with lemon balm.
I think lemon balm and cockroaches will be the only things left! Hahaha I can't kill it off if I wanted to.
Thank you for doing this video..::excited to try the Strawberry seeds from your shop!
Thank you! This explains my st. Johns wort! Going to try your method!
New to your Channel. I want to grow Lavender but never had the luck.
Never heard of this. Thank you.
