It is still officially winter here at Shibui Bonsai but a few warmer nights has stimulated some buds to start growing so I’ve been stimulated to get on with the repotting.
Yesterday I root pruned and repotted all the small shohin sized bonsai. I’ve found that these little ones do better if they are repotted every year. The roots grow fast enough to completely fill a tiny pot in just one summer so the following year it becomes difficult for water and air to penetrate into the root zone and the trees start to suffer.
Starting seedlings through holes in metal plates is not the only way to grow good nebari. I also grow many trees just by regular root pruning to control and direct root growth. Here are some photos to show that method.
