As summer fades and autumn arrives, the light begins to soften. The sun sits lower in the sky, casting longer shadows and bathing the bonsai garden in a golden hue. This shift in light is not just a visual delight—it plays a crucial role in the seasonal transformation of deciduous bonsai.

In autumn, the intensity and duration of daylight decrease. This change signals to deciduous trees that the growing season is ending. Chlorophyll production slows, and the green pigment that dominated the leaves begins to fade. In its absence, other pigments—carotenoids and anthocyanins—emerge, revealing brilliant yellows, oranges, reds, and purples.

The quality of the light

But light does more than trigger this chemical shift. The quality of light—its angle, warmth, and contrast—enhances the visual impact of these colours. A Japanese maple, for example, might glow with fiery red tones in the morning sun, while in the late afternoon, its leaves shimmer with a coppery softness. The interplay between light and leaf creates a dynamic, ever-changing canvas.

For the bonsai photographer and enthusiast, this is a season of storytelling. Each tree becomes a character in a quiet drama, shaped by the light and the passing days. Capturing this moment requires patience and attention—not just to the tree, but to the atmosphere around it.

Tips for Observing and Photographing Autumn Bonsai:

• Watch the light: Early morning and late afternoon offer the most dramatic lighting. Try photographing your bonsai during these times to capture the richness of autumn tones.
• Backlighting magic: Position the tree so the light filters through the leaves. This can highlight the translucency and texture of the foliage.
• Contrast and shadow: Use the longer shadows of autumn to frame your bonsai and add depth to your images.
• Record the change: Take photos over several days or weeks to document how the colours evolve. This can be a beautiful visual diary of the season.

Autumn is a reminder of impermanence—a core principle in bonsai and in life. The colours are fleeting, the leaves will fall, and the trees will rest. But in this brief window, light and bonsai come together in a quiet celebration of nature’s rhythm.
