Great video Jelle. At last! Been practising bonsai for several years. A very clear explanation/description of all the necessary steps needed to grow your juniperus in a healthy manner.
Thx for sharing your knowledge with us.
Thank you so much for your comments!
Thank you so much for that Jelle. It sounds obvious when you show it like that. :)
My pleasure! Most things in life are obvious when you know them!
Good video, this idea of cutting the juvenile foliage is wrongly wide spread.
The emergence of juvenile foliage is the answer to an energy imbalance problem. The tree produces this type of foliage, because it is more cost-effective from an energy point of view, the needles maximize the photosynthetic surface, with low biomass and nitrogen investment by the plant. The tree wants to spend as little energy as possible to produce foliage that allows it to recover energy in the short term. It is often the possible response, in weakened/stressed plants or in plants where foliage has been drastically reduced (imposed and abrupt energy reduction).
the way is to prevent the stress response from being triggered, keeping the plants healthy, being judicious and keeping the percentage of foliage pruned in each season low.
If the tree has already triggered the juvenile response, the most correct thing to do is to NOT CUT the juvenile foliage, (don't stress the organism anymore), and let the tree recover the energy invested and be patient. Correct any health issues and remove small amounts of juvenile foliage in the coming seasons by letting the tree build up its energy levels, until the plant understands that it can go back to investing in mature, scale-like foliage.
The best way to deal with juvenile foliage is prevention.

yup
Very clear and concise explanation thanks Jelle. I have always found junipers and pines a mystery and have killed several with poor handling. I am going to try again as the results that you show are very good and seem achievable with a little care.
Hi Andrew, keep in mind: Open substrate. Lots of sun, and -especially in summer- lots of water. I see many people killing juniper by underwatering for fear of rootrot whatever that might be.
Thanks for the video, Jelle. I'm new to bonsai and definitely new to junipers. Here in Panama, it's difficult to obtain many of the species that are "good" for bonsai. I recently acquired a Parsonii juniper. I've heard a lot of conflicting information about them as bonsai trees, so I'd like to know your opinion on the matter.
Thank you very much for all the great videos; they have been of great help.
I mentioned that I started with a Gardenia. And I'm also working on Spanish Lime trees (from seed).
But I did get a Juniper a few weeks ago, so this video is nice timing.
Keep up the great work, Jelle. Your style is great delivery.
Excellent! Nice to hear my timing is impeccable :). Did you get a scale type juniper?
THank you for the nice comment. I am tempted every once in a while to make more "popular" "blog-type" posts but then I dont :)
@@GrowingBonsai I do not believe it is a scale type. But it is so small, that analysis might change next summer, once it gets a full season of growth. Until then, I'm just leaving it in the sun.
Thx for showing the Right way for a nice grow! And you have very nice junipers ! 👍👍
Ohw thank you!
Thanks for the video, it's very helpful
Glad it was helpful!
Very informative Jelle. Thank you.
You're so welcome!
Very well explained. Thank you🙏
You're very welcome. Glad you liked it!
As always TOP explanation!!
Small suggestion.
When you say that one should definitely not pinch the tips you should also explain why that is not good. By pinching all the growth, you stop the tree from growing, so it stalls. As a result, you can easily lose a few months... you obviously know this, but novice bonsai lovers usually don't.
The goal in any intervention is to keep the growth in the tree
True. Bit of a challenge between packing all into one video or spreading it out. Seems like most people jst skim the first minutes of videos
Very useful! Thank you!
So happy it was usefull! Great to hear, thank you!
Weer een prachtig leer moment, dank u wel.
My pleasure! Fijn te horen dat het bevalt!
Another master class thank you 😊
You are too kind my friend!
@@GrowingBonsai you are a great inspiration for me..
Excellent teacher yelle thank you 😊
thank you michael!
Thanks that was a very good informative video.
Glad it was helpful!
Very helpful. Thanks
you're welcome!
Wish it this apparent when I look at a tree. Thanks for another great video!
Hi David, I find it gets clearer with every tree I work on! Must have worked on nearly a thousand trees by now(!)
Great video, I enjoyed it.
Glad you enjoyed it
Very informative video Jelle
Glad you liked it. Hope you have happy Junipers!
This was very informative for me, thanks! I have been doing a lot of research on how to develop compact scale foliage on junipers and this video answered all of my questions. I do have a question though, what kind of substrate do you use for your itergawa cuttings?
Great to hear! Have you seen my video on taking juniper cuttings? I explain it all there!
Well just another good video. To be honest Jelle up to now nobody share such knowledge about needles [yung ]foliage and scale. Respective where to trim the shoot. First time hearing from you. Keep good growing and look forward you bring more experience tips "How to grow bonsai" Thanks
Jay! Got a "first"! I do sometimes wonder whether people on purpose do not share certain things, or whether it is so fundamental for many artists that they have forgotten that many people struggle with juniper foliage!
@@GrowingBonsai Unfortunately is like that. Thanks you are different
Really useful video 💪
Thank you Brecht!
Great info on junipers Jelle. 👍
Thank you Jason!
your channel is great, I feel kinda jipped by the algorithm because I only found it after the $50 challenge videos from other UA-camrs.
Welcome aboard! I agree. UA-cam is NOT showing my videos to enough people Hahaha!
In which season have you done this?
Great info.😀👍
Hey Magnus, great to see you here!
@@GrowingBonsai last two months have been bussy as you may know? I have an overdue hard prune to do on a red maple. Would you do it now or wait until mid winter? Still a month of growing left.
Very informative Jelle. Only recommendation I have is to include the time of year when you do these techniques.
Good tip! But I time most of my work on the tree, rather than the calender, which is why I go into what a plant should look like. But maybe I should include "during the growing season"
@@GrowingBonsai Yes, good way of putting it. That would be great
Why new foliage and tip of the of the older foliage turn pale green and how it can be cured ? What element or nutrient it may lack ?
Thanks! The first bonsai I styled was a procumbens nana. It's my experiment and abuse tree 😆 I've got some media x blaauw J. chinesis that I've wired but not severely reduced yet. Really nice tight foliage too, but not such a nice colour
Yes, That is what I was thinking. Junipers are the first tree that people get -and kill- when starting bonsai!
@@GrowingBonsai 🤣 it miraculously survived 💪 😆
Nice video ❤️❤️
thank you🥰
what beautiful junipers! do you know if a blue pacific juniper is good for bonsai? i bought one at a nursery and don’t see much online about it
Hi Brandon, going to have to be honest.. I do not know the species/variety and online I cannot see enough. Looks like a needle-type juniper that makes quite tight foliage by itself. I see no reason why it would not be suitable!
I cringe whenever I hear of someone pinching junipers 😬. Junipers are definitely my favorite. Great video Jelle!
I have seen some great examples of pinched junipers though. But it is really maintenance for more developed specimens of looser foliage type species what I can tell that benefit. Need to study this a bit more :)
Oh thank God, just got a juniper, it's not my first, but saw the needles and thought I'd done something wrong, lack of water, or too much light, haven't feed it yet as we are in winter, but Australia is still a harsh environment so started to see one small branch of needles and kinda panicked. I now believe it's a good sign at I can now handle. But as a novice, any advice if obviously appreciated.
:D It ic a bit of a stressy situation, starting out and all that seems off is added concern. I do hope my videos help people understand that most bonsai mysteries are not that secret after all :)
Hi thanks for this video.
When do you do this job cuttings?
What is the best period ?
Hi Xavier, Did you check out the cuttings video? I have not found an ideal time. Normally in later winter, early spring I go through all cuttings of the previous year and pot the rooted ones up individualle. THe healthy, unrooted ones I pop back in a "shared pot" and leave them along for another year. I take cuttings when I prune my junipers, in any season. I have not observed a pattern where I have low succes in one season over an other.
Nice videos you should try the standard shimpaku if you can get ahold of it it's a darker bluer green
I have had them, and still have the odd other juniper species / varieties. I have however the aim to only grow ittoigawa. I like the fresh green look :)
interesting!
What is interesting, my friend in Bonsai?
Do you have a video that discusses watering? Cuttings, air layering and bonsai. Thanks for the great videos.
Hi Mark, I do not have a video on watering, although it is included in my video on dealing with summer heat. I should maybe at one point make one. Cuttings and airlayering.. Several. Take a look at the album with bonsai techniques.
Your video "Keeping Bonsai Green in Summer", PERFECT!! Exactly what I have been looking for. Awesome video! Thank you!
@@markallen623 So glad to hear!
Hi Jelle,
I started 3 Years Ago with a Beech.
Unfortunatly i wasnt brave enough Tonträger my luck on a coniferes. Maybe i Proof my luck next year :)
Do it!
Also Hollywood Juniper or juniperus chinensis kaizuka/turalosa a good one to make cuttings
Great tip
Are you successful Propagating cutting from your juniper I can not recall ever seeing them in the UK for sale ..
I have very good success with them. Have you seen my video on propagating junipers?
You seem to be a master. How did you master these skills ? Do you follow someone or is it due your own working experience ?
Hey Jai, Thank you for the nice compliment. I have been taking lots of workshops with well known masters. Next to that, I am in an international bonsai school from Nippon Bonsai association and the Dusseldorf bonsai school. And now that I have started giving workshops myself I am noticing I learn even more from teaching!
Cutting runners now seems to early to me.I would wait until mid october
Heya Toto, great to hear. What is the reason for later cutting in your perspective?
I have a prickly type juniper that was given to me for Christmas last year. The soil is not right for it as I have learned from your wonderful videos. Should I repot now to help the tree, which is okay for now, or wait until fall? Also, I live in the hot desert. I can not leave the tree in the sun all day during the summer, do I only leave it in the sun during the morning hours then bring it to shade? What fertilizer do you recommend? Thank you!
In a hot and dry climate I would not repot in summer. Also, be carefull choosing substrate. In some climates you do need very water retensive substrate!
@@GrowingBonsai thank you!
Does the same process work on the shimpaku junipers?
Yes
Hi, good Video. Wann schneidest du zurück? Ist jetzt die richtige Zeit?
Hi Ralf, eigentlich das ganze jahr uber. Am liebsten wen den Baum activ wachst, aber gestalltung von wacholder oft ist im herbst / winter.
Will this allow me to be a juniper bonsai master too :)
you already are my friend. You already are.
You already know this is the right pot lol
Hm.. Not sure what you mean!
@@GrowingBonsai at the end , your question ...
@@onizukateacher7992 You mean to say, I selected the right pot?
Yes , ja , da , oui , 是的
