One idea is to gift your friend a beautiful and sturdy bonsai pot that can display their trees well. You could also consider a set of bonsai trimming tools that are specialized for trimming bonsai trees. Another thoughtful gift would be bonsai fertilizer or a book on bonsai tree care to help them maintain their plants. If your friend enjoys displaying their bonsai trees, you could give them a display stand or a book on how to create a beautiful bonsai garden. You may also consider a membership to the nearby botanical gardens, if available, where they can learn more about the art of bonsai and get access to expert advice.
