Thank you Terry. I have watched most of your videos. Very informative. I am comparatively beginner to bonsai. Your videos are very helpful to me. Could you please help me to identify some of my plant species?
Hi Silver Bells, I am glad you find the videos useful. I would be happy to assist with ID but I am not sure how you will show me the photos. Besides I am willing to bet that if you went to your local garden centre they should be able to ID the plants, unless you have some pretty obscure species.
Hi Terry have you done a video on developing the top crown of a pine i am trying understand the procedure needed thank for all your videos i am learning a lot
Mmm Zulupink, thanks for the question. I have not done a video on this specifically although I would have discussed this to some degree and demonstrated it during the style of the pines featured on my channel. I am not sure I could do an entire video on the subject but I will try to remember to dwell on it a little more in the future.
Although I’m not sure what you mean Mark I believe the answer is yes. However I might have used coarser particles at the bottom of the container. For instance medium particles at the bottom as drainage layer and then small particles for the main volume of the container.
Hi Terry, enjoy all your videos! Your advice please, yesterday i potted my JWP, Fukuzumi, from a 5 gal nursery pot to a bonsai pot, and I didn’t cut a lot of roots from the bottom. Hence, the tree sits a bit high compared to the new surrounding soil exposing some surface roots. Could this be a future problem to the health of my tree as spring is just around the corner? Thanks! Keep up the good work!
Hi Kurt. Sure, happy to help. I think that is going to be a problem yes. It’s important when repotting to cut those thick roots and encourage finer roots closer to the trunk or you will have problems getting the tree into a small enough show bonsai pot and/or you will develop a pine which looks perched on the ground rather than clasping the ground. If you don’t have much feeder root and all the roots are coarse then this process of cutting back the roots can be done over a period of years. JWP are not very strong growers but I’m assuming yours is grafted to JBP root stock? in my experience JBP are very tough when healthy and if repotting at the correct time they can respond well to techniques applied to them. Grafted trees are not quite as strong JBP but will be strong than ungrafted. Perhaps it is better to wait now that you have done the work and rather check the response of the tree and then next spring repot again if it’s nice and healthy, if not then wait another season and then try again.
Thanks Terry! My JWP is grafted onto black pine rootstock, I think since it’s only been in the pot 2 days I’ll remove it and trim more roots on the bottom to set it lower in the pot. I have only cut a small amount of roots so I think it’ll be fine to cut a bit more, plus the weather is still cool here. Thank you again!👍🏻
My pleasure Maurizio! When you use this type of media it is necessary to sift the dust particles out before using it. However there is still some small dust on the soil particles and you also can create some dust when you use the chopsticks to work the soil into the roots. All this dust needs to be washed out as best as possible. If not it will accumulate at the bottom of the pot in a thin layer and will be like mud. The roots won’t grow in it at all. After this initial heavy watering it’s best to keep the tree on the drier side until it is showing signs of active growth and then you can water normally.
Not at all. Generally people overpot their trees in my opinion. This presents several problems when over potted but one of them is certainly going to be a balance of water and oxygen - overpotted trees take longer to dry out and the tendency is to water them before that time hence root rot is a potential problem.
Thanks Terry! Just a quick question. Did you trim any of the roots on the section that you didn't bare root, to fit it into the pot? I will be attempting to fit mine from a big nursery container into a big wide collander for further development. It's shallower though, so wondering whether I'm able to reduce some roots from the non-barerooted section safely.
Thanks Shaun. Well I cannot recall 100% but I’m pretty sure I would have cut a small amount of roots yes. The purpose of using this method is to have a section of root ball, untouched and acting as a reservoir of sorts, giving the plant a chance to develop into the new media. The more you reduce the rootball the less the effect. I can’t give you a % or something, but simply try to keep as much of it as possible. Good luck and I am sure you will learn and gain confidence from the experience.

When do you do your JBP repots, Terry? Month? Reason I ask is the local authority on pines Leong Kwong says middle to late winter as the pines start root growth as soon as temperature increases, not a criticism of your info, just a conversation.
I repot any time before the needles start separating from the candles. Pine root activity does start fairly early yes. My repotting window is thus from when I see buds beginning to swell till before the needles separate from the candles. I have no problem with anyone who wants to do it at a different time at all! 😉
Good afternoon. Regarding repotting and subsequent pruning of buds on black pines. There are different opinions on this matter, some believe that the pruning season after replanting should be skipped, some believe that you should limit yourself to breaking off large candles (mitsumi), others believe that if the tree develops normally after replanting, you should still prune the buds . What is your opinion on this matter? I ask because if you don't do the bud pruning you will lose the design of the tree. I also want to ask about the size of the pot. Isn’t it better to plant a tree in a large and deep pot if you want to grow a large trunk?
Great questions, thank you. You are trying to make a grey situation black and white regards decandling. Different situations demand different treatment and it’s not a matter of one persons opinion compared to another’s. They’re all correct. You won’t lose the design, there is no reason you cannot cut back into the previous seasons needles. Yes, bigger pots within reason produce more growth and thus bigger trees. But if you go too big then your soil is going to stay too wet and growth is slowed that way. Smaller pots drying quicker allows me to water a couple times a day and as I use solid fertilizer I effectively fertilize each time. Knowing how big or small a pot to use comes with experience as it depends on so many things. But start somewhere, evaluate the results and adjust.
@@TerryErasmusbonsai Thanks for your reply. Can we really cut all the branches back to the needles of the previous season in a year? And yet I would like to understand more about decandling, by what criteria is it assessed in this case? If growth has not slowed down at all, do we still prune? What if growth slowed down slightly?
What kind of mix do you recommend for someone in Texas, where we have hot summers ( ~ 100 Degrees F average)? Have a few pines ~ 3 years old that I want to start getting them out into a training pot. Is that too soon?
I would ask around in your area what others are using Daniel. This is best. However I would say the basic mix of akadama, pumice and lava would be good, just add more akadama for more water retention possibly. If the trees are in very small containers you may need to water 2 - 3 times a day. I would say 3 years is very short to develop a pine, assuming they were grown from seed. I would wait till at least 8 years I guess, if for shohin. Much longer (15-20 years) if for larger trees.
Good question. No. Never. I always have enough in the soil. Usually too much and it causes problems with watering. I have many pines in my collection and the spores spread between them, at least this is my theory.
@@TerryErasmusbonsai interesting, I picked some up last season and have added it to my conifers, although I have never bare rooted any of them, the seem quite happy. A bit off topic, but have you had any adverse reactions to using akadama with junipers?
@@TerryErasmusbonsai good to know! I personally have not used akadama with shimpaku, or procumbens because a reputable artist said that it’s the worst thing you can do… However, I have seen many people using boons mix with junipers and they look very healthy.
@@dawud7791 I don’t know and don’t want to know who this reputable bonsai artist is you refer to but ask yourself what the Japanese masters are growing masterpiece bonsai in? I assure you it’s not bark and turface or anything similar. If it’s good enough for them it’s good enough for me. There must be a context you are not conveying in which this person said what they did.
I would question the benefit of leaving half the root ball intact in a healthy tree when compared to the potential benefit of providing the tree with a new potting medium. In the least case scenario it could potentially create an uneven growth pattern!
Sure Daniel you may question away! 😀 The technique however is indispensable when working with old trees, weak trees, trees you don’t want to stress further or trees being weaned from a completely different type of growing media. I didn’t think of this technique, Boon Manakipavit did after much experience. I’ve used it many times with great results too.
Thanks Matthew. No, a good mix for this sort of pine is equal parts akadama, pumice and lava stone. Or you could also do one part akadama and 2 parts pumice. Only akadama would not be a good idea for a pine generally as it’s too water retentive.
Terry your knowledge and experience shared by these videos is priceless for someone like me. Thank you.
Thank you John. That’s very kind of you. Glad it helps. 👍🏻😊
Thank you, Terry! A very important measure with the trees as always very well explained. 👍👍👍
Very much details and explanation, and step by step. It’s good and a must for beginners and intermediate in black pines. Well done!
Thanks for that! Appreciate the comments and compliment 😀
Good tip about Boon's method of only bare rooting half the root mass at any one go.
Thank you!
You bet!
Very well explained to repotting black pine. I need to repotting mine in few months, I’m in Sydney.
Awesome, hope the info comes in handy.

Great video Terry!👍
Ha ha. Nope. I’ve been practicing 😂
Great job! Would love to see some videos on younger JBP progression! Thank you
Great suggestion, I want to do those for sure. Watch this space.
Wonderful video and thank you for sharing your knowledge. Gonna be busy spring/summer next year. 😁
Awesome Simon. That’s what I love to hear. It’s great to be inspired and even better to inspire.
@@TerryErasmusbonsai Its my big pleasure to follow your channel and every tip you have been sharing. 😊 I really appreciate it a lot.
Hi ...awesome. Daft question. Was it the same soil you used from start to finish? Thnx.
Although I’m not sure what you mean Mark I believe the answer is yes. However I might have used coarser particles at the bottom of the container. For instance medium particles at the bottom as drainage layer and then small particles for the main volume of the container.

Terry that was a very useful and interesting video! Thank you.
One question. Is the same method suitable for grafted white pine?
Glad it was useful! Yes indeed, especially as the rootstock is most likely Japanese black pine.
Complimenti! Perchè dopo il rinvaso bisogna innaffiare abbondantemente fino a eliminare tutta la polvere? Grazie

Awesome, thank you!
Lot learnt from this video
Thanks great! Thanks
Brilliant as usual Terry. When do you think is best to swap out the 2nd half of the organic/broken down soil? Thanks in advance 👍
I did cover that in the video, 2 years later.
Terry, thanks for info on JBP, do use a str8 Akadama for your pines or do mix anything else into the potting media?
No that would be too water retentive. Use equal parts akadama, pumice and lava. www.bonsaitree.co.za/collections/growing-mediums-and-substrates
Thankyou Terry, much appreciated, enjoy all your info, from Sydney Australia...
Also do you have info on different soil ratio's for the different species ?
Great video, thanks!
You're welcome!
I clean up the whole circle around an in the second transplant do just the center
Sure, thats a good strategy for sure. Thanks for sharing.
Great video buddy. But proportionately, isn’t the pot too small?

Hi Terry the pine that u potted up what kind of fertilizers will u give it
Hi Johan. I use BonsaiBoost all through the growing season. I supplement this with Seagro or Sea Secret every two weeks. Sometimes I add Trelmix too.
So, at some point in time you will end up with no organic soil in the pot, only substrate?
Correct. Organics can create many problems so are best avoided.
