Not long after my deciduous bonsai leaf out, I start thinking about when the perfect time would be to prune and partially defoliate them. In general, the more dense the branches, the earlier in the season I do the work. Once deciduous trees reach a certain density, spring growth on the outside branches shades out […]
Korean hornbeam
Refining a slender Korean hornbeam
A year-and-a-half ago, I started working on a Korean hornbeam by removing a few branches and repotting the tree (see “Defining the branch structure” for details). After pruning and repotting, January, 2020 I let the tree grow freely last year to gain strength after an extensive repot. Here’s the tree last July. July, 2020 By […]
Spring cutback on Korean hornbeam
I usually start thinking about pruning and partially defoliating Korean hornbeam in May. It’s around this time of year that the spring growth hardens off and shades out the interior branches which makes it a good time to prune. Dense foliage on a Korean hornbeam – May 12, 2021 For the last few years, I […]

The timing was just about right for the work as each shoot had a moderate amount of new growth (see “Spring maintenance” for details). This year the tree grew more vigorously – likely a result of being repotted – and was […]

I often begin the styling process by considering how well the branches complement the trunk. On the Korean hornbeam below, a slender trunk supports a relatively full silhouette. Korean hornbeam Full silhouettes make sense to me on trees with more substantial trunks. This got me thinking about opportunities to improve the branch structure by reducing […]
