13 Tips for Juniper Bonsai Styling and Care

Source material: May 19, 2024

            This week I have another post with species-specific tips - this time for juniper bonsai! These are tips from my experience working with and digging this genus, although my experience is still limited. Therefore, as with the last post on Alberta spruce, I also am incorporating here a few tips from online sources, discussions, and club presentations from other knowledgeable folks such as Kevin Faris, Hugo Zamora, Jonas Dupuich, Eric Schrader, and Julian Tsai. Check out their work if you are hungry for more juniper bonsai information! After the 13 tips, I also share a few sample juniper bonsai that Kevin and I have styled and explain how the tips we are using relate to the styling actions taken on these trees. This quick baker's dozen worth of tips is NOT meant to be exhaustive but still I hope this article gets you thinking about this unique and popular bonsai type and hopefully improves your care and styling outcomes no matter your starting point. And for those of you who consider yourself advanced in the realm of juniper bonsai, I challenge you to think of your own tips that I missed and add them to the comments! Maybe I'll revisit the subject and cite those other suggestions someday.

In Vivo Bonsai / Columbus Bonsai Announcements

1. My next workshop is Saturday 6/29, Kevin Faris and I will be teaching beginner-intermediate bonsai styling and care for junipers and yews. For the intermediate level, the junipers we have are unique, aged material (20 years old+), meanwhile for the beginner level we have some nursery stock yews which are flexible to a variety of styles. Sign up and see pictures and full details here and contact me with any questions! There are only 1 spot left and observers are welcome.
2. See my yews, boxwoods, barberries, and consignment trees available in Columbus or with potential delivery to nearby states' bonsai events. Or, contact me to make an appointment at my nursery sometime and see the full and ever-changing selection of seed-grown prebonsai and local yamadori/collected material.
3. The Columbus Bonsai Society's next meeting is 7/20-7/21, our 52nd Annual Show. This year it will be held at a new venue - Chadwick Arboretum at Ohio State University near downtown Columbus. More info will be coming this week and can be found here.

Crazy for Catalpa! Bonsai prospects for an unusual North American native

         If you're familiar with the northern catalpa, Catalpa speciosa, then you know it's a pretty strange tree and certainly not one which you would expect to be used for bonsai. Maybe it's a fool's errand for me to attempt to tame a tree with 12" leaves and 20" seed pods, however something about that staccato, memorable name has got me captivated. I've been observing specimen of it everywhere I go around Columbus as it is one of the more easily identifiable naive trees around - so much so, I've even got my girlfriend shouting "Catalpa!" every time we pass one. From this foundation, basic identification skills had led me to observe the species more intimately. As with any unknown species, the more scenarios you observe a specimen, the more you can observe its potential for bonsai. In the case of the catalpa, observations of a full-sized specimen, the seeding frequency of seeded, the fast growth of those volunteers, and the discovery of one naturally stunted catalpa all inform my plans to experiment with this species for bonsai.

Catalpa is capable of producing a variety of leaf sizes. The left-most leaf is typical for a healthy catalpa, while the right leaves are from a naturally stunted catalpa.
