- Eric shares tips for early development steps on two year old cork oak seedlings. His stock was started from acorns collected in Davis, CA. They were germinated in early 2020.
00:00:39 They've already been wired one time with movement added in lower trunks. Growth has been vigorous so time for second wiring!
00:01:06 Flashback to Mike Pistello's amazing 40-50 years old cork oak.
00:03:31 Eric pulls seedling out of its container to review roots.
00:04:30 Adding additional wire - wiring cork oaks and commentary from Eric on the species. Do you know how these trees provide cork for our use?
00:05:46 Shaved poodle, Eric? 😉
00:06:00 #3 Aluminum wire. Eric wires the tree, explaining how to wire with long-term design plan and scale in mind.
00:08:42 Remember to create 3 dimensional movement! Eric shares his preference for designing informal uprights.
00:09:36 Wiring tree #2 with significantly smaller trunk and multiple side shoots. It's an opportunity to create a different kind of taper.
00:10:54 Comparing two wired trees. Tree #2 has potential to be a smaller bonsai.
00:12:40 Wiring tree #3, twisting while bending to create more interest in the bark as the tree matures.
00:13:43 Batch in gallon containers, while same age are significantly bigger with multiple shoots.
00:15:10 Wiring larger tree #4. Eric's timing for wiring oaks is when they are actively growing. Deciduous oaks in Spring (in Northern California) and Corks in late summer. This avoids dieback.
We do have limited stock of Cork Oak starters available in single, two- and three-packs: www.bonsaify.c...

I just want to tell you, there are many bonsai channels, but I have few favourites amongs them, that I really enjoy to watch, and I am impatiently checking for new episodes.. and your channel is one of these. Great work, great wisdom, great videos! Thank you 👍😉
Thank you so much. I started my cork oaks from acorns collected in Modesto a few years ago. The little trees are so vigrous, I need to start looking for guidance for starting to shape them. Your guest's tree is truly incredible.
Clearly information here. Learning a new plant species for me
Very informative video and nice variety of oaks. Thanks for sharing!
thank you for sharing this bonsai tree video 👍🛑🙏🙏
on Mike's awesome oak you guy's were talking about the thick upper branch, but i like to call them trunk extensions, like an oak in the wild, a lot end up being multi trunked.
Usually in Spain and Portugal the cork grows back and can be harvested again between 9 and 15 years, the trees must be at least 30 or 40 years old before the first harvest
Yeah I went to UCDAVIS they had this cork oaks planted all over the town and the campus they are more than 100 years old when the University was created 1908 as a farm University. The cork oaks only grow in south west Spain and Portugal. They are forest of cork oaks, the ones in Davis came from this part of the world because many Portuguese moved to Sacramento at that time from the island of Madeira . That’s the connexion since they don’t grow in another place than this region. They are absolutely gorgeous very tall and a beautiful bark grey color.
I’ve got a cork oak from the iohnsteen company a few years ago and it’s still alive! Here in Richmond Virginia, I wonder if I’ll be able to keep it alive for a long time- did well outside the past couple years though!
Thanks for the video!
Portugal is the world leader in cork. We export approximately US$1.1 billion annually. 62% of the world's cork exportation are made from our country.
Thank you for this video. I’ve been following this same approach but it’s good to know I’m not messing them up. I have some cork bark oaks I started growing from acorns at the same time as these but unfortunately I’m up in Seattle and I don’t get nearly the same heat and vigor of growth you get.
That's funny, I think the same thing when comparing to growers in LA.
Eric, thanks for following up with this video. The one I got from you last month has adjusted to its new spot on my bench and is now growing like a weed so your video came just in time. I just sat down and put a bunch of new curves into the 4 straight shoots that are about 8-10” long. Hopefully with all the fresh new growth they will do well.
Any other tips on timing of things like repotting and how they take root work in the spring would be appreciated. Also it would appear that if these in 3” pots are moved to gallon pots next spring I might get explosive growth over the next growing season. So your thoughts on repotting and root disturbance would be even more important.
While young I would concentrate on combing and arranging the roots. I've seen them die from overly aggressive root work, so be careful about how much you cut. Timing wise - early spring is best, but keep in mind these are not a cold-hardy species. Zone 8 USDA, but in a bonsai container I'd aim for 28F or above.
So this one just keeps on growing, when do they usually go dormant? Since I received it the main stem has added at least 10” of new growth. I wired and twisted all three shoots and they have extended 2-3” beyond the wire! I finally tried an experiment and snipped off the end of the longest one to see it f I could get it to backbud. I plan to put it in my garage for the winter as my wife already hates it when I bring my Brazilian rain tree into the house each fall. I had a slippery elm that refused to drop its leaves last year that I then wintered in the garage and it is growing well in spite of not having a dormant period.
Lol. Yeah you have to let bonsai get kinda big and lanky for a while if you want the larger trunk and bark.
Being a coastal mediterranean species it is likely opportunistic - as long as conditions are right it keeps growing. We see this with a lot of coastal California trees also.
👍👍👍
Can you do a guide care for cork oak specially winter care ? I’m from Pennsylvania

Would it be a viable solution to apply the wire when dormant, then wait to actually bend once it's growing? It seems like that way you get the best of both worlds.
Great question - and I assume it would - although you do bend the branch a little just by applying wire. But, I think it could work.
Eric-so based on one summer of growth these seem to have a tendency to just take off and grow like crazy extending long branches and stems. So instead of just chopping these back and tossing them in the compost, how well do they root as cuttings or as air layers?
Dirr says that cuttings of all oaks are difficult but not impossible. Use a high PPM IBA rooting hormone (perhaps Hormex #16). I believe air-layers can be successful, but cuttings might be a bit frustrating! In any case, success with either would be heat- and rapid growth-dependent, so better left for late spring/summer.
Does cork oak grow in Bloomington Indiana?
Great video, thank you for all the insight, but a quick heads-up, that even has been mentioned in the comments.
Although not an incorrect comment when you mentioned that cork oaks can be found in Spain and in most Mediterranean countries, they are much more abundant in Portugal, which is the one of, if not, the largest cork supplier and exporter in the world.
Side note, I have recently bought a piece of land that has several mature big cork oaks, and I'm trying to grow a bonsai from them. Will a stem work or do you advise planting seeds?
Thanks in advance!
I think you can air-layer them, but not cuttings. I could be wrong, but I seem to recall that oaks are basically never propagated by cutting.
I just planted a couple hundred acorns that came from the cork oaks on the UC Davis campus. They don't harvest the bark out there, so it's a gnarly campus. So, my strategy is acorns. Unfortunately, in the northern hemisphere you just missed the season to pick them. See if there are any left?
How difficult is it to propagate oaks from across? Do they need scarification or stratification?
When do you cut the tap roots?
I’ve grown Texas live oaks from seed 2 years ago. Had them in 1 gallon pots from seed. They grew long. I repotted on the second year in bonsai mix and cut the tap roots off. I’m going to check them on their third year and move them to larger shallow pots.
Tap roots aren't a myth, but they are mis-understood. They are just a big root essentially, you can cut it back after the first year or two, then continue cutting it back as the tree makes more lateral roots and you repot a few times more in subsequent years.
Would these grow indoors for the winter? I know its way to cold to keep them outside in the snow belt.
I don't know for sure. Probably not ideal. Maybe possible.
From little acorns grow great oaks. How long would it take for these newbies take to develop acorns and are they in proportion to the tree or big?
Oaks normally take quite a while to start making acorns. I've never seen any on my 17 year old valley oaks, but I trim them normally so that may be the issue. They tend to be slightly smaller, but not miniature...kinda like the leaves.
While I don't have any cork oak, I do have a number of other oaks that I've started from acorns and this year one I started in 2000 began developing a few acorns.
Are the acorns mini ones or near actual size?
@@Bonsaify Nice one, that really clears up the confusion on my part. The Oak tree is actually Welsh and not English as the text books would suggest?
@@9daywonda They were small, but that's because they aborted very early in their development.
its a bummer california oaks are the only ones that like being bonsaid lol i have tried a lot with red oak around here and they really do not respond well. once you touch the roots on red oak they will die back for a year or two
I've been growing red and white oaks and didn't know this. I cut the tap root on them when there acorn was still attached without a problem.
Just for the record - Cork oaks are not native to CA, and they are more usable than any CA species I know of. Q. agrifolia is finicky. Doable, but finicky. Q. lobata is also doable but can be finicky. I've tried many others that are native to CA with little success. Blue oaks for example are just plain frustrating.
Q. robur is usable from England. Keep looking!
@@jameswalker3416 what kind of soil mix do u use for them?
@@Sherman_616 50/50 safe t sorb and potting soil.
Which is the best soil for Cork Oaks I’m in SoCal!.
1:1:1: APL would be my choice.
@@Bonsaify Thank you very much!. Great video I just bought my first Cork Oak. Your videos are very informative thanks for sharing!.
