My shohin Japanese maple grew well this spring which makes it a good candidate for defoliating. I removed the leaves, pruned a few long shoots, and covered the surface of the soil with moss. Before defoliating After defoliating – 7″ tall When the new shoots begin to emerge, I’ll pinch them the same way I […]

Spring maintenance for a refined Korean hornbeam
After fifteen years of branch development, my Korean hornbeam has slowed down considerably. When I started working on the branches, I’d often see new shoots with ten-to-twenty new leaves all over the tree. Now I can expect between two-to-five new leaves on all but the strongest branches. Korean hornbeam This slowed growth rate simplifies spring […]
Leaf pruning vs. partial defoliation
Spring is a good time for managing vigor on deciduous species. We can fully defoliate our strongest trees, and partially defoliate less vigorous bonsai. An alternative to defoliation for species with larger leaves is leaf pruning. Leaf pruning works best when you want more light to reach the tree’s interior but you don’t want to […]
Follow-up – defoliating a shohin Japanese maple
I fully defoliated a shohin Japanese maple about six weeks ago. Here’s what the tree looked like after removing all of the leaves. Shohin Japanese maple – April 30 After a week, small buds started to appear along the branches. May 10 – new buds appear Tiny back buds The first new leaves waited almost […]
Focus on defoliation – determining how many leaves to remove

The question I’ve been asking in recent years is, how many leaves should I remove? Last year I took a fairly conservative approach. Here’s […]
