Re-potting Dawn Redwood Pre-Bonsai
HTML-код
- Опубликовано: 21 окт 2024
- It looks like spring is coming around! many of my trees are coming out of dormancy, so I figure now is a good time to re-pot these dawn redwoods into some larger grow-out pots. I hope to grow large trunks on these two and hopefully the hard root prune pays off!

I just subscribed to make sure i see the update on those two trees. That was a lot of root pruning.
Few advice for the next time based on my experiences:
1. Wrong pot size, it’s too large. You need a colander.
2. Wrong root cuttings. Too much, you need to leave more small roots in order to growth faster
3. Washing the roots remove the mykorizza fungus, without this the growing slowdown
4. Wrong soil. Do you need pomice and perlite to grow fast
That is spelled Pumice
Good God man, leave something for the tree!
It would be great too see how these are doing now. :) I just acquired a Sequoia and thinking about using these techniques on it.
What soil do you use? I understand they are more on the acidic side.
@@carolficorilli9768 at the time I was going to boarding school and only saw the trees once every few weeks. My parents agreed to water them, but they were busy with work and taking care of bonsai trees were not a top priority. I used 100% pine bark, nothing else. This was purely for water retention in the Louisiana heat. So the soil was relatively acidic, but it is in no way the ideal soil mix for the species. Over the past 5 years, the trees have been in the ground, although one died in a hurricane. The soil is mostly clay and sand, but they seem to do well in similar soils to Bald Cypress. The trunk is roughly the size of my forearm now, but the summer heat definitely slows their growth in USDA Zone 9. I recently moved further north, so in the spring I'll be digging the tree up (along with a big Bald Cypress) and putting them back into large training pots with soil mix that will be more conducive to root density to get them ready for pots in 2-3 years. 1/3 pine bark, 1/3 diatomaceous earth, 1/3 calcined clay. Heavy fertilizer and bone meal for acidity if i notice anything
Did these trees survive this pruning? It looks like way too much of the root mass was removed, especially the feeder roots
They survived just fine. As I expected, they did not put on a lot of growth this season, but their roots are already holding them stable. I expect this next season to be a good one as far as growth goes and I'm hoping they'll start putting on some size.
looking forward to seeing the spring growth results. I was just given a Dawn Redwood that had been a bit on the root bound side and I replanted it as well. I left the roots alone though do to the time of year. Soil is a bit to on the Basic side though so I will be amending it with some sulfur/sulfite and bio-char. Do you have a Facebook or Instagram page as well to follow?
Thanks for watching and I'm sorry I'm just responding. I've grown these trees in almost 100% pine bark for most of the time I've had them. It's only recently I've seen a decline in health due to lack of nutrients (I haven't fertilized in months, whoops) but other than that nothing to report. I do have an instagram (@collinserigne), but I focus mainly on photography there. I'm hoping to put out some photography videos in the future but not really sure how to do that yet. Again, sorry for taking so long and thanks for watching!
Please keep us updated on these though out the years
wow that's alot more root removal then i ever thought possible
Yeah, I was sorta worried I was pushing them a bit too far as well. I'll make an update video soon, but both trees have started to push growth and are growing just fine!
Collin Serigne I'll stay tuned as i just picked one up for my chameleon enclosure. Currently trying to scramble and figure out how to keep it alive ect.
I thought the samething about the major root cutback, that was a lot for a sapling like those. I am also nervous for the oversized pot. luckily DR like water, but that organic soil may not drain as well as needed. But one never knows with nature, ha. With the radial roots you desire, you could have used what you had and shape them with each repot over the years, those seemed good for a nice nebari in the future. But DR grow fast, so enjoy. was one of my first trees I wanted when getting into Bonsai. I'm currently growing a bunch for a future forest planting. Be well.
will keep an eye out for an update, I am curious(for my own experimenting) if that large of a pot would be o.k for that small sapling. for the radial roots, I have found shallow and wider pots do well for a nice nebari.
Thanks
Thank you! I'm not super concerned about hurting the trees right now lol. I've had them for a little over two years now and got them as two year old seedlings. This was there first real root pruning so far. I'm looking to get a decent trunk size, but I can't really put them in the ground where I live (basically straight clay down here). So they'll be in those pots for the next few (like 5-10) years. I'm not worried about the pot size and the soil drains pretty well and holds a good bit of water, if not the soil would dry really quickly. I'm about to be home for the summer, so look for updates soon!
I'm sure you will be fine. If you were going for larger trunk and the larger pot, I am thinking maybe just leave the roots as they were to get quicker, vigorous growth. But as I said, nature finds a way.
I actually just got a tall, 6foot DR today, surprisingly from a box store. HAHA. I got it for the size, and Im preparing an air-layer now for it, there is a perfect spot a third of the way down with a scar, and will achieve the trunk chop and get me a 2nd tree. the more the better!!
Be well, and I will look out for updates.
The metasequoia is good at working with naked roots.
but in minute 2:08-2:17 of video where you have a root zone and mycorrhizae below.
The next time uses that area where there are roots, soil and mycorrhizas. You do it to pieces of more or less 2 centimeters and you use it as a base as the first layer to re-plant the tree, you will see how the result of the new rootedness improves by 80%.
It's just an idea and experience with the conifers.
😘
I love small treez
this is how a comment on a bonsai video should look ^^
Awaiting the update video as well. I think a number of us were wondering about the vigorous pruning. BTW, what is your location and growing zone?
The trees are growing much slower than normal, which I expected, but they're definitely pulling through. I'm in the lower part of Zone 9 close to zone 10 I think (south of New Orleans Louisiana). I'm Hoping to have an update video very soon. Thanks for watching!
Do you have any tips on repotting Giant Sequoia? Mine will need doing soon for the first time, but I've read that they're very difficult to repot successfully without killing the tree.
Honestly, I don't really know much about Giant Sequoias (Sequoiadendron giganteum?). I haven't had much luck with them, but I only ever tried to grow them in Louisiana. I know that they are a bit more on the dry side, especially when compared to Dawn Redwoods or Coastal Redwoods. I would guess it has a lot to to with what zone/climate you're in. I would stay true to the seasons though: re-pot late winter/early spring right before the tree starts putting out new growth.. Nigel Saunders says that as long as the plant is re-potted before it starts pushing out new roots it should be fine, but the buds are a good way to judge. I would treat it more like a juniper or pine than a deciduous species and not go overly crazy with how much root you take off. If you're just going for adding some thickness to the trunk and aren't too worried about nebari/surface root direction, I wouldn't mess with the roots at all, just tease the outer roots and slip pot. At least until you find out how the tree reacts.
I just got some seeds from some trees on campus here and I'm hoping I can get a few to germinate. I'll let you know how that goes. Let me know what happens and if the tree survives its first re-pot! Good luck, hope this helps.
Many thanks for the information, very helpful. I’ve read that they should be treated like a juniper, so ill definitely adopt that approach and be very cautious with repotting. I’ll be interested to see your progress if you manage to get some to germinate!
It's the same but use Lava rock next time. I have two as bonsai .
How about an update on these Dawn Redwoods plz
Im guessing these two didn’t make it....
They've been doing great! these past few months have been absolute mayhem, but the redwoods are still going strong! My parents moved, so I ended up having to plant them in the ground at my grandparents house. The buds are just starting to bud out and this should be the second year with no root disturbances. I'm hoping this year I'll see some crazy growth on them! Also, if you look at the where are all the trees video, they make a quick appearance.
Collin Serigne nice to hear brother interesting root trimming would love to see the trees in a new video sometime 🙏
Checking in on these DRs. Have you posted an update after that root prune?
Not yet. I'm working on some videos that I've been putting off for a while. A video I was recently working on got completely deleted, so that sucks. But their are some more videos coming up (hopefully) pretty soon!
Any updates?
If you would have just used LAVA Rock you wouldn't have had to do this.
Well, my plan was to plant these in the ground sooner or later or even let them grow out in their containers for years. Planting them in lava would have created more fibrous roots, but I have no intention on putting these trees in bonsai pots
within the next 5 years at least if not more. Regardless, adding lava rock wouldn't have fixed surface root structure and it would still have been a major prune to get things where I wanted them. And now they're in the ground and will hopefully be for the next 5-10 years until I have somewhere to put them. I do hope to have a better soil mixture in the future, but as of now, and for my duration of growing bonsai this far, anything besides my pine bark soil was far too expensive and time consuming. Also, for a majority of the past four years, I have either been in boarding school or college, so I didn't want to invest a lot of money into a soil mixture for a tree that could have been killed by my parents and pine bark was a great option because it is free flowing and retains a lot of water, which is very helpful on 100+ degree louisiana days when my parents would inevitably forget to water the plants. Like bonsai mirai said in their watering video, more water does less harm than not enough!
He is killing trees stop this man
Theyre goin strong so far!
