In the last post we looked at the benefits of removing root sprouts on developing bonsai. We can take the same approach with water sprouts.
Water sprouts are shoots that emerge from the trunk and generally grow straight up. If we don’t plan to use these branches in the final design, it’s best to remove them as soon as we see them. This is especially true for water sprouts – or any branches – that emerge on the lower part of the trunk.

Letting branches grow on the lower part of the trunk is undesirable as it leads to scars when we remove these branches. Even when I’m creating small bonsai, I try to avoid using sacrifice branches that emerge below the lowest primary branches.
While working on the above quince, I noticed some of the wire I had applied in winter had started to cut in. A little cutting in is OK on young deciduous trees that are still developing, but too much will leave scars that disappear slowly, if at all.

Here’s what the tree looked like after removing the low shoots and thinning a branch or two higher up on the trunk.

I plan to revisit the tree in a month or two to wire new shoots and remove or reduce branches that aren’t contributing to the future design. In the meantime, I’ll be checking all of the young deciduous trees in the garden to remove any root sprouts, water sprouts, spent flowers, or wires that are cutting in.

Jonas, I assume you might leave new shoots on lower trunk of a quince, for example, if you wanted to increase girth of trunk?

Hi Ed and Lars – I rarely use sacrifice branches below the first branch on the tree as I don’t want scars on the lower part of the trunk. There are other ways to create low taper (develop good roots; use sacrifice branches higher up) that avoid scars along the most important part of the trunk.

Hi Jonas,
Is there any downside to leaving a watersprout to use as a sacrifice branch in order to thicken the lower trunk. It seems like these might be ideal since they grow fast and don’t need to be wired to get good sunlight.
