Baggie Method Seed Germination
Вставка
- Опубліковано 31 тра 2024
- A quick way to start or test seeds is the baggie method. Sealing the seeds in a sandwich (ziploc) bag in a paper towel or other growing medium traps the humidity and helps the seeds to germinate quickly. Remove from the baggy promptly and carefully transfer into a pot or longer-term home for growing on. This is a popular method for germination testing, seed stratification, and it remains popular with cannabis growers, where the large seeds are relatively fast and easy to handle once sprouted. There are pros and cons to the method, which I'll cover in this video.

I use the containers from grapes, blueberries and strawberries to plant my seedlings in. (The taller ones) They have drain holes at the bottom and a top with holes that allows the air to flow and keeps moisture in. I let the seedlings grow to their first true leaf and sometimes beyond and then transplant them. I don’t waste space or soil and I can see what seeds are the most vigorous. This works best for me for seeds.
Thanks. I like those clamshell type clear plastic containers for humidity - the vent and drain holes make a much more forgiving environment!
I had already decided not to use this method again, and when I saw this video I thought: “oh no Jason is going to try to convince me otherwise” 😂
I 100% agree with your analysis: the post-germination process is too stressful for me! Again, as always, you’ve provided a great balanced and realistic view.
A little peroxide mixed with the water used to moisten the paper towels helps prevent mold and rot!
Thanks!
Happy New Year Lisa, Jason, and family!
💯% agree.
I have used the baggy method hundreds of times for testing sprout rates and germination of new seeds I'm not familiar with as well as to see how vulnerable they are to over moisture issues.
Most of the time I will use a thin layer of potting soil or peat/perlite because the seeds can readily root in the medium. I use the inexpensive potting mix with only a small amount of fortification to lessen the impact of root burn and rot.
The baggy method is an excellent way to teach kids and new gardeners how germination works because you can actively check the progress without much risk of damaging the sprouting seeds and you can actually see what is happening.🤙
Thanks and happy new year! You're right: it's great for teaching and demonstration, but as a practical method for starting seeds, it has some drawbacks.
@@FraserValleyRoseFarm
Yes, there are actually a lot of drawbacks, but the real issue is that it's just not a practical method for propagation.🤙
i do my peas, beans and bread beans in a bag with moisten soil, shopping bag more than sandwich and i tie it closed into a knot..works like a charm
Another informative video. I like the idea of using the plastic box. Thanks.
I use clamshell deli containers from the supermarket. I line the bottom of each one with two layers of paper cut from a paper towel, and one layer cut from an unbleached coffee filter, so I can see the little white roots against the brown paper. I wet them down with distilled water from a spray bottle. I don't know if that helps prevent mold, but I've had almost no problem with it. I sprinkle the seeds on top of the paper and close the lid of the container. I don't cover the seeds with paper. I put the containers in the cabinet above my freezer, which stays warm from the heat given off by the freezer. Roots are somewhat less likely to penetrate the coffee filter paper, but it still happens. That's why I try to plant the seed in seedling mix as soon as I see the little radicle emerging.
I use the baggie method mostly on pepper seeds. A couple of years ago I had the idea to use condiment takeout cups with lids. I placed a small paper towel piece in the base of it, mositened it and just laid out a number of pepper seeds on it. They germinated as fast as they did in the baggie but they weren't cramped between the plastic or the papper towel. They were free to stand tall and reach toward the light. Like you mentioned however they did root slightly into the paper towel. Another drawback is the small size of that container if you wanted to do a larger number of seeds. I suppose that a larger container would produce the same result. I also have had some success with placing the seed on the soil in a plug tray and keeping a moisten piece of paper towel on the plug. That way it roots into the soil, and the paper towel keeps it moist. I enjoy your channel and your experiments, keep it up!! Happy New Year!!
I use the baggie method for apple seeds to grow apple trees👍
I’m glad I watched this video! Thank you!😊
Thank you for this video, really informative and helpful!
i use a old t shirt ore cloth that i rip up and clear plastikk boxes, :) the roots dont grow stuck and its easy to open and close and to remowe the ones that are ready, " planterull"= plant roll, is simular but its the same princip as the baggy metod, a shet of plastikk that you cover with paper\cloth, make the medium moist\wet and place the seeds, then roll together, place in a cup with water and make a plastikk dome.give it a search on yt if tou havent seen it. happy new year to you
Thanks - great method!
Thank you! I wanted to look this up since it's been awhile since the last time I tried this and this was helpful
Smart! Doing this clear bag tip today.
thats cool using the storage tubs
happy new year, enjoying these short videos, I use baggies for trees and shrubs that have a long germination period, and to test seeds, i try and space seeds across the paper towel so if they root into the paper i can cut them out and plant paper and root
That's a really good approach! Better than damaging the roots for sure.
Thank you for your video and information
Happy new year and thank you for all your information
Very much my pleasure!
Helpful comparison, thanks 👍
I love poppies! They have a bad reputation from starting from seed, can you do a video on them or maybe you already have one. Thank you! Happy New year!
Thanks. I'll put it on the list.
They do? Mine always start from seed, often by accident
I’ve only used this method with larger seeds (nasturtium, sunflower, etc) so I don’t bother planting seeds that aren’t going to germinate because they’re going in a space with specific placement. Never thought of the method of laying them on top of the planting medium, I’ll try that for sure!
Thanks - excellent for germination testing!
Thanks Jason.🌲💚🙃
I found the same issues when I tried the 'baggie method' a few years ago. I prefer the seeds germinte into soil. It's easier to move them on.
I just watched a video on tree germination...made sence...start them poor poor soil...one the tap root and the two fake leaves appear move to good soil...trees will grow about 50 times bigger..seen it
One thing I did to avoid the handling is to space the seeds apart enough to be able to get a pair of scissors between them and I cut the paper towel and just planted the hole thing paper towel and all. Worked just fine and the paper towel decomposes in the soil.
Good technique!
Thank you.
I saw a video someplace on u rube where they didnt use paper towels...cant remember what they used..i think...but am probably wrong...i am pushing 80 after all...but something really really thin...like those used as hand wipes rewashed a lot...then again it maybe thicker...the disposable shop cloth comes to mind...but i really think it was the thing stuff
Anytime I use this method I’m checking them every day and have tweezers ready. I typically use a container, like your bento box, and a paper towel.
With really SMALL seeds I prefer to use mini soil blocks & 2 seeds per mini block.
Good call - checking daily makes sense for fast-germinating seeds, and even for cold stratification, I like to check every week or so in the fridge.
Happy New Year. I stopped using the tissue in the bag because the tiny roots of my lavender seeds were so tideous to remove. I killed the seeds more than i planted them. But you give the idea of using sands in bag. Here, we have a couple who successfully planted several varieties of raspberry and blackberry. The seeds do not need cold stratification anymore. However i lost the seeds when i accidently flipped the tray over and spilled everything!
Use toilet paper which dissolves
I use the baggie method for sweet peas and geranium, both of which are hard for me to germinate in soil.
Thanks!
Happy New Year Jason and Family.
How often would you mist the cuttings and seedling in the house?
I want to say Thank You for recommending South Africa rose in your Tropical Rose video. It has done very well in our very hot summer.
Happy New Year to you and your family as well. I check daily, but only mist as needed. For cuttings in propagation domes, I usually judge by the condensation on the inside of the plastic. For open trays (of seedlings, for instance) they need to remain consistently moist until seeds germinate, then I reduce the misting frequency to lower overall humidity and encourage the seedlings to root into the medium.
@@FraserValleyRoseFarm still amazes me that a cutting the size of a tooth pick can root and grow into a plant.
Hi Jason! I am a big fan of your channel. Quick question regarding rose seedlings from wild roses (natural pollination), I’ve been sowing and germinating from hips I’ve collected from various rise gardens. Most of them grow and bloom as shrubs with pink single petal flowers with no scent. What’s your experience with wild roses?
Thanks!
Regards from Costa Rica.
Ricky
Thanks Ricky. Our native wild roses are quite well adapted to the local climate, making them a nice low-maintenance option, even if the bloom period is quite limited.
I use baggies some use them to germinate a couple plum seeds and now they’re about 2 inches tall
If i get a random pod from a rose bush, would it need to be in the fridge for a while? Happy New Year from Northern Ireland.
I'd take the seeds from the pod and either put them in the fridge as shown in this vid, or stratify outdoors like in this other video: ua-cam.com/video/YGjF9-vxPmE/v-deo.htmlsi=VrHiAbhKlI3Vx5gN Happy new year to you and your family as well.
Jason, can you tell me what clear totes you're using, whose lid will fit a 10x20 tray? I've not been able to find anything with typical depth that will hold a 10x20 and still let the inverted clear tote fit over the tray... thanks in advance for this and for all your amazing work. I'm not growing roses (yet) but I've learned a TON from you.
They a Sterilite 58 qt Storage Bin (1847 is the model number). They're just a little snug on the long dimension of 1020 trays, and a little wider than they need to be on the narrow dimension, but they're plenty tall which I like a lot for longer cuttings.
@@FraserValleyRoseFarm thank you! That's the one I most recently got to try, and so that's what I'll work with. Thanks again, for everything!
This works great for seeds that may need scarification. Hibiscus germinated in 2 days on heat inside covered tray. I did this after trying to nip one and it flew down the drain🙄.
Thanks for sharing your experience!
Happy New Year Jason. For stratification, I have new native seeds which will require a cold period. Are you saying I can go ahead and start these in a growing medium in the fridge right away? Ie, they don’t need to be refrigerated in their packages first, then potted up? I have only tried a fridge a couple times with seed packets but they didn’t grow. Maybe I need a whole video for that?!
Thanks. I did a recent video on cold stratification, but didn't focus on the baggie method (rather, I did it in potting soil and seed trays). Here's the link: ua-cam.com/video/YGjF9-vxPmE/v-deo.htmlsi=PB5j3q0g4k1R0H5l The main point is that the seeds require consistent moisture in combination with the cold, generally for 2-3 months. Whether you do it in the fridge or the outdoors is your call, but chilling the seeds dry doesn't work.
@@FraserValleyRoseFarm oooooh, well, that explains a lot then! lol thanks!
Hi Jason, about 6 months ago I put some seeds (Box wood and yew) in my fridge for a number of weeks to make them think they had gone through a winter. I then took them out but never got round to planting them. So they have just been left out at rom temperature. Do you think that I should just sew them or put them back in the fridge again?
It's a tough call. I'd probably go with a cold moist stratification - a lot of tree/shrub seeds will sprout even through cold temperatures, so if they didn't get what they needed the first time, another stretch may help. Consistent moisture is important for the process.
OK thanks I will give them ago😊
How do you keep seedlings in a tray from growing spindly when sprouting indoors w/o elaborate light set up?
I don't know about elaborate, but light certainly helps. In terms of timing and placement, that usually means cheating towards the time they'll go out into the garden (not starting too early) and getting them close to a window so you only have to supplement natural light. Speaking of light, it doesn't need to be a dedicated grow light. The kind of white LEDs used as shop lights or fluorescent replacements are plenty efficient enough for a few seedlings. Other factors: air movement up, humidity down, temperature down, all within limits - still, moist & warm is a recipe for stretch.
Hey Jason, an excellent video. My question Is about spray bottle ph. What ph do you have in the bottle? Do you change ph for different germination? Thank youy for your help.
Our water is pretty soft and close to neutral, so pH has been (thankfully) kind of a non-issue for us, and I haven't needed to adjust it.
What I wanted to know, for example, would rose seeds want a certain ph and say tomatoe seeds need something very different?
@@FraserValleyRoseFarm
No, not really. There may be some exceptions but when I buzzed through the research for the various species, it's a fair pH range that will work, centering on a slightly acidic to neutral solution being optimal for seed germination and early development.
Thank you for your insight.@@FraserValleyRoseFarm
Hi I'm just beginning to get into rose breeding I have a question concerning if there are any rose breeds that will not breed with the other, for example can I breed a hybrid tea with a floribunda?
I can comment on the basics - yes, most HTs are compatible with floribundas. Most modern hybrids like these have the same # of sets of genes (ploidy). If you want something more specific, it'd be better to seek out the rose hybridizer's forum where they get into all the details about which make good pollen or seed parents, and which genetic characteristics are likely to dominate.
Would you blow air into to make it more off a doom?
There's plenty of air inside for the initial needs of the seeds to germinate, so I probably wouldn't puff them up.
My main issue with trying to germinate seeds for a spring planting (Salvia, Zinnia, etc.) is trying to produce sufficient heat and/or sufficient light for a small number of plants desired (15-20).
Makes sense. I suppose it depends on how much a head start you want - the close you get to spring, the less supplemental heat and light is an issue. But for a small number of plants, it might be practical to start near a window indoors. Seedling temps aren't too different from comfortable home temperatures. As for light, again, for a small space even a screw-in white LED and a desk lamp may be enough to supplement natural light.
Ok, me again. Seed packet says to cold stratify for 6-8 weeks. What if the seeds sprout before that time? If they do, does that mean they’ve had enough and are good to pot up and put under lights? Thanks Jason!
Yes, early germination is quite welcome - and they're good to grow on!
Hi Jason!!! Happy New Year!!! I have yet to watch this video but I had to come here to ask if you've watched Olga Carmody's latest 2 videos.?? (She is reading from 2 wonderful books) I believe you follow her channel. The videos are utterly intoxicating....just lovely really. I think you would enjoy. 😊
Thanks. I'll check them out.
I tried this with astrantias but no success, even after cooling the seed in the fridge.
Ive ended up putting some seed in the garden to go through a natural winter.
I still have 12 seeds.
Any ideas?
Thanks, Jo.😊
No, not much beyond what you're already doing - some seeds require more than one cycle of cold and heat to break dormancy. I'd maybe try a hydrogen peroxide soak 0.3 to 1% overnight and see if it kicks them into gear.
Wish I saw this video first. I just did this with my seeds. Now I’m worried they won’t turn out when I transfer them into my egg cartons with soil.
Well you can always just cut the paper with a little knife to avoid disturbing the roots.
I use this method for Sweetpea. It saves rodents snacking on expensive seed
Good call!
