Thanks for the vid, its good to know im not the only one who likes to plant things and watch em grow
Just an update on my dragonfruit seeds. I used your method here and it only took 3 days for them to sprout! :) I live in Georgia and its been rather cold here so i kept them inside the house next to the window. I also put some seeds in a moist paper towel and put the towel into a plastic ziplock bag. 3 out of 6 sprout in the baggy :) But I deffinitly like this method here! Thanks again man for the great video.
This is one of the better of the videos that I found on youtube covering starting succulent seeds and was just what I needed to be confident planting this round after my last attempt never sprouted
You should really think about putting together a pamphlet or small paper book. You have lots of great information and you don't get too technical. I would definitely buy one. Please keep making your videos.
same
So would I, excellent idea
Thanks for the guide brother ive got 6 bags with different types of cacti all germinated at about 8 out of 10 seeds per bag! No mold so far and fast germination just over a week! 3 different strains so it works well with all kinds even the starfish seeds which are noticeably bigger seeds than the tiny black ones.Happy growing thanks again!
Thank you ,your method seems to be working ,I followed all your instructions step by step and 7 days after planting trichocereus seeds they popped up green and all.
Thank you cactusmain!!!! I was able to successfully germinate Lobivia jajoiana seeds following your method with 70% germination rate.
BEST video I have seen on the subject...nice work.
Ok... I am using this technique today... excited to see some babies! Thanks for this video.
good video! i learned an grew hundreds from this very guide over the years... ....
I just started my first batch of seedlings. I did my soil differently. I use the DE that I can get form walmart for pretty cheap. I use it in my regular cacti mix as well with good results. I have been growing for a few years, and just undertook my first batch of seedlings. after one week I have gotten C. gigantea to come up so far. I did lots of others. I am using modified baggie method with containers but I have to mist them. I check mine twice a day.. So far seems to be working...
Hey Cactusmain, This video is very informative. I sowed some VICTORIAE REGINAE AGAVE seeds on 6-24-14 following your method.
I just checked them today 6-29-14 & I already see that 5 of them have germinated. Don't worry, I'm not going to mess with them, lol.
I'll wait 3 or 4 months to do that :). Thanks again for all the info you share.
Hey man, I just wanted to stop in and say thanks so much for the helpful videos.. I used these techniques for my seeds on Sept 10th and I have so many sprouts already.
awesome so glad to hear!! I love hearing success stories on growing from seed! good luck and happy growing!
+cactusmain hey I just started seeing what appears to be green growth on the surface of the soil I'm going to assume it's algae...will this be a concern?
+Alex Parent green is alage from excess nutrients. shouldnt be a problem at all. it will go away once you get to the air out stage :)
@cactusmain Thanks so much for your answers. My seedlings are right now about 2 months old and their spines look more like hair than spines. That's why I was concerned about squeezing them during transplant.
Potting soil straight from the bag has a very high moisture content, hence the steam after microwaving. Thus in return one could make the statement of being scolded, instead of burned. Technicalities shouldnt validate one being a fool. Thank you for viewing my videos :)
how long must i microwavw my soil please
They never grew for me
Rustyben nineoneone sorry to hear they never sprouted for you. Growing cacti from see is definitely slow, but very rewarding when you get a seedling to bloom. What species where you trying to germinate?
.i'm not sure what cakti I was trying to germinate but i got them on ebay packet almost looked empty I wanted my money back but she explained to me the seeds are very small see through plastic bag to me anyway i've given up on growing cacti good luck to everyone on this page
Thanks
Good job, nice hints, I'm growing various seeds I buy on the net, with drastic differences in culture. Try growing fern spores if you want to learn patience! I especially liked the quick reference to heat and Loph., that will be useful.
Wow nice Video very well explained I will following the steps... Thanks
Thanks so much for the helpful video! I ordered some cactus and succulent seeds the other day and hope to plant them soon. Really helpful video. I would have just put as many pots as I could fit into a bigger bag, so thanks for pointing out why you use one bag per pot. In the past, I tried to grow a packet of mixed cactus seeds and they got to the point where they developed tiny spines, but then they turned red and stopped doing anything. I had them under some shop lights, but maybe too close to the source? Anyway, hopefully this time will be better! Now I need to go watch your other videos!
Thank You for posting this video. My first seeds died and I now an trying this method. Im confident it will work thanks!
Very good video, thanks for answering all my questions.
perlite is generally ok, it does however tend to float to the top of the pot when watered. The best over all of it is pumice.
Great Video my friend :) Your so right about forgetting when you plant seeds... i rarely label mine yet i ALWAYS regret it later... lol.. When will i ever learn :)
I will try my seeds growing in a plastic bag.I hope this time it might work.Thanks for the tip.
Great video man! Im trying to grow some dragonfruit seeds and this video just answered all the questions that I had. Thanks :)
Thanks for posting. Was wondering how can you tell when your cacti seedlings are ready to be transplanted into larger individual pots and is there any special consideration you must take when doing so?
Interesting. Thank you for your reply. It makes a lot more sense now.
Thanks for this video, very informative.
Perfect video. Been looking for this exact information. One question though, when do you transplant baby cactus to an individual pot? How big do they have to be and how do you not squeeze them to death when you transplant them?
I did not microwave my soil before planting. (didn't know that step) However the seedlings are about 2 months old and are about 1/2" high. I noticed that there might be a fungus or discoloration on the Perlite. Can I transplant the seedlings into better prepared soil now? Or should I just wait and see how they do? They are a light green and look healthy with no "red" spots.
I will follow your steps with the next batch I plant.
Most welcome. Counter intuitively, plants that grow in harsh conditions are among the most fragile. Alpine plants for example, are difficult to start from seeds.
Really informative and clear tutorial, thank you so much!
@OlliMSa Thank you. As for transplanting the seelings, I tend to wait as long as I can. If you do it too soon there is a chance the seedlings will be shocked and either die or sit dormant for months. A good rule to go by, is to wait till there are a few sets of spines which resemble adult spines. Maybe 2-6 months after removing from the baggie. As for squeezing the seedlings- they are alot more frim than they look lol.
Thanks. Good videos like this are far and few between for cactus cultivation
Beautiful pictures on the wall! 00:02
i also had my cacti sprouts :) very beautiful
My Bergerocactus emoryi seedlings are 4 years old this year and out of the original 8 I have 4 surviving. My biggest one is 2" and the smallest one 3/8" and 2 i between these sizes. It's interesting to have many different sizes and growths when the seeds are all planted at the same time.
Cactus seeds often germinate over a long period of time, so that the first to sprout are quite large before the last ones appear. Just take good care of them and they will eventually catch up.
thanks for the tips as i just planted seeds about 1 week ago
I don't get how your directions could work. I totally believe that your directions are really good for growing cactus but I just wonder why. Could you help me with my questions?
Because in the wild, cactus grow 1. without microwaves 2. without coconut soil 3. without humidity, let alone plastic bags and 4. and has PLENTY of sunlight throughout it's whole lifecycle (so how could sunlight be to strong for seedlings?)
Hi! Love your video and thanks for posting. I have successfully grown some cereus peruvianus seeds thanx to your post! My question is, when do I transplant?
So once you get the pot in the storage bag you don't find that you need additional misting to keep the soil from drying out until the bag has been completely opened to acclimate the cactuses and is removed?
Really awesome, complete video. Thanks!
Would you reccommend using perlite and pumice together such as in your older video on creating a soil mix or just one or the other?
Hey Cacticalmain, this is the best video I've seen yet and I have searched and watched all that I can find, I am using a 10 gal. tank for my seed chamber and you mentioned that you lined yours with foil, is that correct and can you send me a pic of yours & your light? This is my first time sowing cacti seeds and I just started some (mixed) a couple days ago to see how they do with my basic setup (hood with light and a grow light) should I leave a gap for air to get into the tank? Did you say you just use a standard fluorescent bulb, is that with a hood or without? Is that the only light for the entire 3 months they're in the baggie? I wish you would do more videos especially on growing them and basic care, you just explain things really well even I can understand. Sorry with all the questions but that's another reason you need to continue the videos, after all these yrs. you have new students coming by. (Late but present) TY very much I will continue mine as you have taught me.
I’m going to try your way on this video, thanks for the information
Also i noticed on your cactus soil mix you added osmocote to it. Do we add this to the seed mix? Or do we wait to do that set of videos when the cactus grows a year old and ready to be transfer it to a bigger pot?
One more question, is the perlite a substitute to using rocks or sand? Which is better? I read on various websites that one must use rocks and sand, but you don't mention it. I trust your methods i am just curious on what is the best.
Excellent info....thanks. I assume when they have been removed from the baggy you continue to bottom water them until you divide them into their own containers?
Thank you was so helpful ... when u have them in the bag don't you water them? And when u take em.out after 3 months approximately how often do. U water them?
+Ella Emanuel No watering at all while they're in the bag. The moisture from the soil is all that is needed. Since the bad is closed, the moisture/humidity just recirculates and keeps the soil moist. Once you take them out, watering will depend on the plant. With that said, most succulent seedlings are hard to overwater (unlike the adults), just don't drown them. I generally water seedlings a couple times a week, but I'll go by feel - if the soil feels dry, I water.
Hey man, Your video answered a lot of questions. I was curious if you had a video out there that discussed separating all the cacti when they have all grown so close together like that..
sure do glad the video helped!!

Thank you
Live in Spain. Have a Cactus I don't know the name of, it has a red non-spiky cap. It sprouts seed pods that look like peppers. They have 20 + seeds in.Haven't done all you advise, will try now, mine have been in Cactus compost, blotting paper and in a garden over 6 months now. Have put them in whole or emptied pods. Nothing has sprouted, do I assume they've died. Let's face it they grow in nature with know attention so I would've thought a few would've survived? Any thoughts/advice?
Cheers AL
excellent video, good work
how do you water them when they are in a zip lock bag. and when is the best season to sow the seeds?
Awsome video, it was very informative. Do you have any good sources for different seeds?
I tried your method! I planted them two weeks ago and they are doing great! I was wondering if this method will work with lithop seeds?
Thanks from a succulent and cacti enthusiast :)
Hi Cactusmain, i just wanted to thank you for your videos on growing cacti from seed. i have watched a lot of them and yours among a few, made better sense and explained the procedure pretty well. my question is, have you tried anti fungi solutions in? a lot of growers in my country are using them. some of them dont. but most of them dont microwave the stuff either... so i was wondering if you have used them or have any comment on the subject.
One or two balls of osmocote wont hurt, but i tend to not fert any seedling mix, there is more than enough nutrients in just the soild itself.
Thanks for the vid. My question is do we use regular potting soil or cactus potting soil?
What is the best soil for adult cactus? And where can I buy good cactus soil on-line?
When you have many thousands of seeds you can just sow and a handful will grow despite the conditions, some seeds will even bide their time. That's why they don't literally cover their natural habitats. But when you have a limited amount of seeds (and time) you want conditions that are as close to optimum as possible to ensure a success rate that's unnatural, and optimal growth.
Incidentally, you'll be creating optimum conditions for fungus and other blights, hence microwaving and plastic bags.
is the pot going to be in the bag for 3 months without watering?
Hi, i have a question. When the seedling leave the bag....say October do u continue to water them over winter? They are in unheated outdoor grow room under a shop lite. The lowest temps hover around 30 degrees outside in winter. Nothing has ever froze inside the room.
Do you have to water them inside the bag?If yes how often?
3.5 months is up- out of the bag. how often/much should i water them?
I have a big glass bottle that I want to plant them in. The only thing is is that I won't be able to get them back out again.. Would this be possible? If so how will it be?
My girlfriend just bought me a grow your own cactus from Urban Outfitters and the instructions were awful so thanks for the video!
Oh my god I'm in the same boat! Such a nice gift but also expensive and with little advice to decrypt. Love cactuses though and can't wait for them to germinate! 😊
I got some saguaro seeds and just tossed them on some potting soil and now I have a hundred babies growing strong. Now I just need to know when and how to separate them.
You said to continue to water those four month old cactus but you didn't say how. Do you water from bottom or top?
very clear instructions. Do you use Ziplock bags for euphorbia seeds? and another question .how many months after germination, do you transplant them into individual pots?
Hey Cactusmain thanks for the video. I was wondering how wet the soil should be? Should I let the water soak until the entire pot is saturated, or just let them soak up some water for a few minutes and call it good? I tried this earlier and after sitting in water for a couple of hours the pot was still only about half saturated with water. I figure I don't want them to be too wet, but wasn't sure. Thanks again for the help.
Question: You say don't open the bag for the minimum of 3 months if so how do I water the cacti?
do you know what the ones that grow that realy big red ball and have a green stem are,i have one and want to know how to take trimmings and grow them
No, once you soak the pot with water then seal it in the baggie, there will be more than enough moisture for months.
Where do you get your seeds from?? I have only found them at walmart SOMETIMES and they dont even say what kind they are. it's a bunch of different kinds. do you have any website suggestions or stores?
thanks for this useful video i have question my seedling six old month still in plastic bag can i open it but temp very hot about 38dg and can i fertilizer thanks for your time.
I have 15 Pilosocereus cactus ( from 20 seeds) I started on 8/2/2015 following your instructions. They are all doing well. However three of them have a light brown color while the others are bright green. Full disclosure I did add a bit of water as the pots were drying out at month two. I opened the zip lock bag just enough to stick the spout of a watering can in and add the water. Are the brown ones an issue? Besides the color they seem healthy. Will opening the bag a bit help? I'm about to start that process anyway on 11/2/2015 anyway. Great video and growing cactus from seed is addictive.
Could 35% h2o2 replace the use of a microwave for keeping soil clean? I haven't used a microwave in almost 10yrs and don't even own one.
Are you effectively sterilizing, or pasteurizing the soil? Also, is the water sterile or distilled? Why not add it before sterilization? Doesn't the sterile environment become contaminated during the cooling process?
I tried to germinate 10 lophophora seeds without the sterilization process and they smell like a dirty diaper.
Also it's been in the mid 60's here, should I wait until spring to plant my new seeds?
Apparently you can open the bag early if you want. Doesn't put them into shock. Got 3 successfully germinated.
How long dose it take for small catuses to grow from the seeds. i planted my seeds about a month ago now and notthing is happing yet and do you keep a light on them all the time and howch do you have to water them.
Question for growing thanksgiving or holiday cactus in bag method i know its a min of 3 months in bag but whats the longest i can leave seedlings in bag?
please make a video of how to grow peruvian apple,dragon fruit and prickle pear from seeds.
Hello
I have a question pls.
What times do you water your pot after seeding and putting it in plastic bag?only one before germenating?!
does that mean when u take the seedling out of the bag you have to keep it wet until it's big enough to withstand the dry soil?
what sort of advice do you have for me for growing them in the UK as we don't have the weather you have.
How many hours a day should the Florence light be on? and when is it that they should be transplanted to their own pots?
Cactusmain, does this work for every cactus including t. Peruvianus? Also, instead of using a bag, could I use Saran Wrap and gradually poke holes in it?
wow thank a lot inspiring and beautiful :)
How long after you see them start to sprout should you take them out of the bag?
Hey friend! Awesome informative video. I am not growing cacti at the moment, but i just came across a small number of seeds from a particularly rare guy and i absolutely canNOT let them go to waste. I only have five seeds, but I am determined to bring life to them. is there a way I should be storing them in the interim? and should I do what you did in this video only with a much smaller number of seeds? PM me if youd like to talk more about it, I could definitely use the help.
very useful video! gathering informations for my trichocereus seeds!
Blackat92 awesome thank you for the kind words! Good luck in your seed growing endeavors!
If i dont have access to flourescent light will indirect sunlight be sufficient ? Also i have a heat mat so can keep the temp well enough
Thank you! Any good advice specific for trichocereus?
Danny J should be ok, just keep eye on them, red-less light, stretching more light :)
Blackat92 patients lol, they take a long time :)
Some of mine turned out skinny and streached out, will they still grow ok?
I have my first batch on its way, only a month gone so far and I have shoots. I found the best place was in the bathroom close to the radiator, as it's pretty cold and wet here in Ireland. I am a total beginner though and considering they are mixed cacti it looks only one specie has germination early. I will leave th for another couple of months, I think it may have been better to get non mixed but fingers crossed &
i dont have a tank, but i have a closet that has a bright light in it can i keep it in there?
Hey Cactusmain, I have just tried this method... fingers crossed, just wondering after the 3/4 months how do you go about transplanting them in to bigger pots, what soil etc.? :) TIA
How do you tell when it’s time to start watering them as adults?
awesome video dude, I got some seeds...now I guess I will have to wait a while to do it
Don't I need to wet the seedlings until they are ready to come out. Or is the the moist from the pre-watered pot enough to keep it moist?
so uh, do you ever seperate them? or you just let 20 cactus crowd the small pot forever?
Great video, I have a question; I placed the pots in a small fridge that doesn't work anymore, put a lamp inside and turn it on during noon/night time (about 12 hours max) and then turn it off for the rest of the day, Im concerned as to whether I'm giving the seeds too much light and heat (it gets quite hot in there if i don't open it for a while) they've been there for about a week now and, i know it takes longer to germinate but I'm just worried since i dont want to cook my seed. Any advice regarding my situation will be greatly appreciated
after the 3 months, how often do you water them?
