    Leaf burning on Hornbeam

    Hi everyone. This is the second year I have been faced with a strange disease on my Hornbeam. The first time was at the end of summer 2023. This year it appeared earlier, in May, mainly on the leaves of the apex. In 2023, this combination of fungicides helped me: difenoconazole + flutriafol +...

    Found a beautiful hornbeam grove!

    I was walking my dog this morning and he pulled me into a really nice little hornbeam grove. There are quite a few trees here that I intend on collecting soon with great nebari and spread. One of the trees, presumably the grandfather, had a massive trunk with a 15"+ diameter (dog head for...

    Oriental Hornbeam bleeds. Is it dangerous and when to prune?

    Hi everyone. I prune some very thin branches on Hornbeam and it started to bleed, before that I hadn't dealt with Hornbeam, is bleeding for it as dangerous as for Maple? Should I postpone pruning until autumn or after the leaves mature?

    Hornbeam drops leaves after being transported

    About a week ago I became the owner of Oriental Hornbeam, it was delivered to me by a transport company. T he seller packed it well: sealed the crown in polyethylene, covered the container with sphagnum moss to avoid drying out. I watered it for the first time after receiving it and didn't...

    American Hornbeam #2 Progression, Caleb C.

    Here is another Carpinus Caroliniana I collected in December 2020. It has a rather straight trunk, but has a massive (comparitively) opposing root flare. Will be a nice, straight, shohin+ haha. Wish I got pictures of the roots when I potted it. Upon Collection: Leafed out in February and here...

    pH correction of my Hornbeams and Field Maple

    Do these trees need alkaline soil? I used bark in all my mixes and I think the soil turned a bit too sour after a couple months. And can they withstand chalk? I have horticultural chalk (something like that) and I could dilute some wood ash in water which should also raise pH. Of my Korean...

    European Hornbeam direction help

    Got this back in July and finally got a good look at its branch structure. It’s about 27” tall and 1 1/4th” thick. I’m either thinking about air layering below that curve, or just growing it in this 5 gal container for a few more years and letting the trunk thicken up. Curious on...

    Lost as to what is wrong with my Hornbeam

    I’m still struggling to figure out what’s wrong with my American Hornbeam. A ton of leaves have these black spots showing up on them. I suspected fungus so I removed all the leaves with spots and sprayed with fungicide some weeks ago, but that didn’t seem to have any effect on the tree. Overall...

    European Hornbeam Stalled

    My first time with a hornbeam but I found them interesting because of their legendary vigor. I picked up this nice pre-bonsai from a guy back in the early spring (this year) and it did precisely one thing: leafed out (as you can see), but nothing else. Meanwhile my other trees have been like...

    Hi everyone. Seeking urgent advice. I accidentally left my hornbeam bonsai out in direct sunlight (in 24c heat) for 3 days, without a drop of water. I came back from a long weekend to a very poorly scorched little bonsai. The leaves have yellowed and gone all crispy dry. See the photo...

    Help! Worried my hornbeam has a fungal infection.

    I’ve started to notice these black spots, burnt edges, and holes developing in some of my hornbeam leaves. At first I thought it was sunburn but after hearing many people discuss how their hornbeams can tolerate full sun I am starting to think it’s a fungal infection. The tree does seem semi...

    Can it be salvaged?

    Hello, I Have a Korean hornbeam, I suspect the roots have dried out, was neglected over the winter, not watered regularly. I repotted the tree and am seeing some spring growth, some leaves have budded sporadically through-out the tree. Does that mean the tree is still alive or able to be...

    Should I remove the dead leaves from my hornbeam?

    I inherited this hornbeam last year. I'd like to keep it going as long as possible, but I've absolutely no bonsai experience. The leaves turned orange over autumn and I half expected them to fall, but they didn't. Now its early spring and the leaves are still here! I can also see some small buds...

    Artificial Intelligence meets Bonsai

    Carpinus betulus, Hornbeam nebari

    Developped from 1 year old plant. Planted in the ground and groundlayer one year later. This is the second repot after that. It's basically a stick in a pot with a rootbase. I planned to groundgrow this one but I was afraid to lose the rootbase so I put it back in the box. If I want a tapering...

    Beech (Sylvatica) & Hornbeam (Betulus) Thread Grafting

    Background A month or so ago I began exploring the potential for thread grafting these two 'similar' spp. Scroll down to see the graft and spare the interpretation/justification of this futility! :p:D:p I soon found out that these visually similar spp. are in fact completely different. Genus...
