    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...

    Is this sunburn on my Hornbeam?

    I’m wondering if anyone has the answer to this. I’ve noticed some new growth on my Hornbeam has started to develop this brown edges to them. The edges while brown, are not crispy or dry when they first develop. My tree is kept in the shade for as long as possible throughout the day, but gets...

    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...

    Next up is Carpinus caroliniana, The American Hornbeam. I am new to all of this, so don't take this thread as advice (unless it isn't coming from me). It was propagated from seed last year. I bought it in a one-gallon pot with 80% pine bark. Leaves have already opened obviously, but I tried...

If I cut both leaders off and go with the blue line, I'll lose a year or 2 in growth on the top. I like the lower left...

    American Hornbeam

    Starting a thread to track progress of the american hornbeam I got a few years ago. It's the first tree I've put into an actual (albeit cheap) bonsai pot. Current goals: - Thicken middle portion of the trunk to improve taper - Continue developing branching, particularly in the empty space on...

    Hack's "This is not a contest" tree

    Hello all, I've collected a trio of American hornbeam this winter and really hope to develop my skills on indigenous decidous, say that 3 times fast! I used @Zach Smith advice from his bonsai South website for collecting. I'll sort out one primarily for the contest provided they all survive...

    Root pruning American Hornbeam

    How aggressively can you prune the roots of an American Hornbeam? Last year I collected an American Hornbeam from my parent's property in MI. It's been growing in a large growbox since then. Today, I've been repotting the other trees I collected and since they all have small rootballs, I put...
