Seed Scarification Speeds up Germination (compare methods)
Scarification is the process of weakening the seed coat so that air and water can enter the seed more quickly, thereby speeding up germination. This pre-treatment is only required for seed that has a tough seed coat.
In this video I’ll show you several ways to scarify seed and show you how to remove the tails from seed like clematis. I’ll also show you how to avoid damaging the seed embryo while scarifying the seed. This is important because a damaged embryo will not germinate.
The best method for scarification depends on the size of the seed. A file works great for large seed. A knife and nail clippers work for medium sized seed. And sandpaper is the best method for very small seed. Lets have a look at all of these methods.
A file works well on large seed. You can use a triangular file, or a regular flat file. If you are using a flat file, hold it at an angle so that the corner is making a V shaped cut in the seed.
You can put the seed on the table, and run the file over it like this.
But I find it easier to rest the file on the table, and run the seed over the file. This way round seed is less likely to go shooting across the room.
You want the groove to be deep enough so that you can see the white inner seed, but you want to damage the inner part as little as possible.
For mid-sized seed nail clippers work quite well. Use them to chip off a small amount of the seed coat so that you can see the inner part of the seed. You can also use a utility knife, or an Exacto knife.
Take a sheet of sandpaper, and lay it flat on the table. Place the seed on top. Now take a smaller piece of sandpaper and cover the seed. Gently slide the top sheet back and forth. After a couple of passes you might need to move the seed back into a pile so you can scratch them some more.
With small seed I don’t try to scratch them enough to see the inside of the seed. Their seed coat is not very thick, and some minor scratches on the surface will usually do the trick.
Lets have a look at a seed embryo. These are peanut seeds that have been slit open. You can clearly see the embryo inside the red circle. Think of the embryo as the baby plant. It is usually small and located at the end of the seed that was attached to the mother plant. Here is a close-up of the embryo. The rest of the seed is stored food for the baby plant.

After watching your videos, my work efficiency improved by 1000-fold. I can't thank God enough for introducing you to me. Being my teacher, you will always be in my prayers. Stay blessed! 💕

[@linzerpa]

I feel like I am an expert on this now in under 7 minutes! Thank you.

[@charlenegarcia5144]

😅

[@sarayost5619]

great examples, thank you

[@NightRunner417]

That intro music... It's like I came here to learn how to scarify my seeds for the coming apocalypse. Cool. Thanks for the video, helped me a lot! :-)

[@mehranashkanian2747]

Great videos you have. Congrats 👏👏👏👏👍👍👍

[@pinkypete6079]

one method we use to use back in the day was to get a match box and take the striker part from the side and place inside the match box then put your seeds in the box and shake gently this roughs the surface up especially on older seeds

[@raphlvlogs271]

5:14 was the large round seed in the middle from an entada plant?

[@sereezee]

The sandpaper method is absolutely brilliant! Tnx so much!

[@frankieg7575]

subbed thank you

[@rickwest4497]

Sandpaper method is great for old cannabis seeds, thank you!

[@charlenegarcia5144]

Thank you, that was very informative

[@johnjude2685]

You nailed it, I been trying to learn so I can raise plenty of Bird house gourges for a second day class, Last year I fell to get plants early enough to get 22 but only 7 gourges and some undersized due to late start because of germanation issues. I think you have made a happy second grade class into a art class. Thanks for the best video I am very confident now. This is the best video,Sir

[@KarineTKnudsen]

Wow! This video was truly amazing! I have never heard about the method until watching your video. I have some passionflower seeds that are a little old AND STUBBORN! I will have to try to cut off the side opposite to the embryo side. Thank you for making this!

[@introtwerp]

i just pressed the seed until they spilt a little

[@moonlightzanelengubane713]

An eye opener indeed, thank u🙌

[@oystein18]

Thanks for the video! My seeds had a thick layer on them. This should speed up things.

[@ImAChristianFirst]

Excellent tutorial. I didn't know how to do this without destroying the embryo. Now I know! Thanks.

[@alexandertowns8431]

Any thoughts on growing bamboo from seed?

[@CyberSERT]

I learned a lot! Thanks.

[@Arabian_Gulf_Angler]

Thanks.. Your sand papar method is actually strong enough to crack a seed.. The other methods i found on KZbin are just too gentle to crack it enough to sprout! You just saved me alot of money and time my friend so I'll subscribe to your channel 👍.

[@lanoredixon170]

I have learned so much by watching a mere handful of your videos! Thank you for such educational material!

[@amirmahdi2891]

you are genius! thank you❤

[@Gripmasters]

very good video! thanks a lot for this. but I wonder do I still need to soak coriander seeds and water Convolus seeds? and than scarify them? or first scarify and than soak? or will scarify and directly plant works? Soil is in a tropical climate and very clay like.. it tooks weeks for the water convolus to grow up..

[@DumpstaJuice1]

I wonder if mixing seeds with sand in a small container and shaking vigorously would work.

[@HaphazardHomestead]

Nice demonstration! What's the hardest seed coat that you have had to scarify?

[@ragav194]

I have seen tons of videos, but none like yours. You are a researcher! Great work sir!

[@jeffreydustin5303]

A+ presentation!

[@coeneschamaun1735]

I was just trying to determine which end of a morning glory seed was the embryo. I'm afraid I may have damaged some. If I'm correct, I now believe the pointy end is the end I should scratch, because the other end is the embryo. Or try to nick the side edges, as some other videos have suggested. Can anyone confirm this? Thanks

[@Gardenfundamentals1]

I think it is the rounded end. You should still be able to see the scar where it was attached to the mother plant. When in doubt, do different seeds, differently. Then at least some are right.

[@rizwanrashid5621]

Sir how can we do this with blueberry seed

[@Gardenfundamentals1]

Use the file.

[@airbornestud3007]

Is it safe to do this on small seeds like mustard seeds or even poppy seeds?

[@Gardenfundamentals1]

Yes, provided you do it carefully. But do they need it? Most seeds do not need it. Most poppies don't need it.

[@airbornestud3007]

@@Gardenfundamentals1 thanks👍

[@350streetracer]

It is better to elaborate which side tu cut. I read is it better to cut on the embryo side since the root will grow that way.

[@Gardenfundamentals1]

Provided you don't damage the embryo. The reason for the cut is to allow water to get in. Once that happens the root will find its way out.

[@kamillemaddux5091]

thank you for sharing your knowledge...so helpful

[@roberttrembath3670]

Will this work with vegetable seeds like pumpkin and watermelon

[@Gardenfundamentals1]

Works for all kinds of seed.

[@bobmcwilliams4416]

Awesome video. I have no idea why 16 people would down vote this.

[@philipkeeler9997]

They work for Monsanto.

[@rosarioparra8956]

what grid was used when sanding the little seeds

[@Gardenfundamentals1]

What ever I happen to pick up :)

[@stephencarlsbad]

With smaller seeds you'd probably want to use a finer grit.

[@nitelite78]

Very interesting and informative.
