    Help Rooting Olive Cuttings

    Yesterday I removed several thick cuttings from my European Olive because I'm removing a branch. I've potted them up in a mix of about 50/50 potting soil and pumice. The containers all have drainage holes in the bottom and sides. I trimmed much of the foliage, covered the major cuts with putty...

    Brown Spot on Japanese Holly Cuttings

    Just curious if anyone has insight as to what might be going on here. Probably a very basic question with a lot of possibilities, but I’m still trying to nail down propagation. I have these guys in pure perlite and noticed some are browning on leaves. Moisture looks to be fine, but maybe they’re...

    Maple cuttings failing in propagation box, user error?

    Hi, I'm relatively new to propagating maple cuttings and need some more experienced advice. My Japanese maple cuttings last summer dried out while under the deck. Even after misting half a dozen times a day, the high heat, humidity, and wind won. This year I tried a clear tote propagation...

    First Air Layer of Red Maple in Front Yard

    It's through bonsai that I discovered what "air layering" was so I thought I'd give it a try on this Red Maple I have in my front yard. I believe its a bloodgood and there's a couple others on the same and neighboring blocks since they seem to be popular here. I love the color they give during...

    Hong kong Kumquat/ Kinzu

    Hello Everyone, Does anyone have experience with Kinzu as bonsai? I've seen allot of pictures of them in Japanese exhibitions, but information on them seems practically non-existent. Also, are they able to be grown as cuttings, or do they need to be seed grown? Thankyou

    Ficus nerifolia propagated in a large outdoor pot

    So this tree was a little clipping on February 2021, now it is shaped nice. I had it in a 3 gallon pot, outdoors since May, topsoil. The roots were mostly fine and radial, did a 10% root reduction and 10% off the top. Goal: To reduce the height by 2" and get new branches where the lower...

    Growth rate many airlayers vs single plant

    Hey guys, Lately I've been quite obsessed🥴 with propagating japanese maple cultivars via air layers and being as efficient as possible at it, i.e. maximizing growth/gains. I keep wondering whether having many smaller plants of the same cultivar produces a generally higher amount of accumulated...

    Accidental Groundlayer Adventure

    We just closed on a great new place and I’ve been taking stock of the flora on the property. At first I was annoyed with the messy unkempt beds of azaleas that hadn’t been cleared of fallen leaves but realized many had thrown ground layers under the rotten leaves! Will try to leave some to...

    Ezo Spruce cuttings

    My friend gave me an ezo spruce this summer because I’d been talking about taking cuttings and trying to propagate more for the future. I’m lucky enough to have started bonsai relatively young(30’s) so this is a project I’ll be able to see through. I recently completed my first attempt and took...

    Zone 10 Japanese Maple

    I’ve got 10 of these right outside my dorm. I never really bothered with them but now I’m getting curious whether I could pull it off. Now, I figured it might be too hot but then I remembered that if you pot a tree it jumps down 2 zones. I can clearly see that the trees that get some afternoon...

    Humidity Tray "grid" - there's got to be a better way

    For ease of watering (and upping the local humidity) I'd like to put some of my tropicals on humidity trays. I am not a fan of the tray+gravel+pot method, even though the gravel does look pretty. I'd prefer a nice, sciencey looking grid, like these Humidi-Grow trays that Bonsai Boy has. The...

For $75, I got a 6' tall Shishigashira Japanese Maple in a 6 gallon nursery can. It appears to be grafted about 5" above the soil line, but it's...
