The ginkgo (Ginkgo biloba) is a living fossil, a tree unchanged for over 250 million years, with unmistakable two-lobed, fan-shaped leaves that blaze a brilliant gold each autumn. It's an outdoor deciduous tree, and it has one unusual quirk that shapes how you grow it: the ginkgo resents heavy pruning, since its cuts don't heal cleanly. Rather than fighting it, you work with its naturally elegant, upright form. Give it sun and a cold winter's rest, and it rewards you with one of the most beautiful fall displays in bonsai.

An outdoor tree, and a survivor
The ginkgo is a hardy deciduous tree that lives outdoors and needs a real winter dormancy, so give it winter protection in colder climates as it rests. It's astonishingly tough: ginkgos are pest-free, shrug off pollution, and are so resilient that four trees survived within two kilometers of the Hiroshima blast and still grow today. In a pot it stays small, reaching only about 16 inches by age six.
Light
Give your ginkgo full sun to partial shade. The more light a mature tree gets, the more spectacular its golden autumn color, so a bright, open outdoor spot is ideal.
Watering
Water well through the growing season, keeping the soil consistently moist while the tree is in active growth. As it drops its leaves and goes dormant, cut back sharply, keeping the roots just barely moist over winter, enough that they never dry out completely but never sit wet.
Fertilizing
Feed twice a month during the growing season with a balanced fertilizer diluted to half strength. Stop as the tree heads into dormancy.
Styling: work with the ginkgo, not against it
This is the ginkgo's defining quirk. Unlike most bonsai, it doesn't take well to heavy pruning; large cuts leave scars that don't heal over, so aggressive branch removal spoils the tree. The graceful solution is to let the ginkgo be what it wants to be. It naturally grows in an upright, columnar or flame-like form, so style it in that direction with light, thoughtful trimming rather than bold structural cuts. Pinch and tidy new growth to keep it neat, and resist the urge to make big chops.
Repotting
Repot every one to five years depending on the tree's age and vigor, less often as it matures. Early spring, before growth begins, is the best time. Refresh the soil and prune the roots only modestly.
Common problems
All the leaves turning gold and dropping in fall. Completely normal and, frankly, the whole point. The ginkgo is deciduous; it shows off, sheds, and releafs in spring.
Slow-healing wounds or dieback after big cuts. The ginkgo's known weakness. Avoid heavy pruning; shape with light trimming and work with its natural form instead.
Dull or sparse fall color. Usually too little light. Give it more direct sun through the season for a richer autumn display.

FAQ
Is a ginkgo bonsai indoor or outdoor?
Outdoor. It's a hardy deciduous tree that needs full sun and a winter dormancy, and it can't live indoors.
Why shouldn't I prune my ginkgo hard?
Because its large cuts don't heal cleanly and leave lasting scars. Style a ginkgo with light trimming, following its natural upright, columnar form rather than making big structural cuts.
How often should I water a ginkgo bonsai?
Generously through the growing season to keep the soil moist, then much less in winter, keeping the roots just barely moist while it's dormant.
Why are my ginkgo's leaves turning yellow?
In autumn, that's the natural golden display before the tree drops its leaves for winter. Outside of fall, check that it isn't being over- or under-watered.
Is a ginkgo good for beginners?
Yes. It's tough, pest-free, and forgiving, and because you don't prune it hard, there's less technique to master. Just keep it outdoors, sunny, and watered.
