Ginkgo trees (Ginkgo biloba) are ancient survivors that require all four seasons—spring, summer, autumn, and winter—to grow properly.
Famous for their golden fall leaves and prehistoric origins, ginkgo trees start their journey from a smelly fruit that hides a surprisingly beautiful seed.
This post shares how I grew a ginkgo tree from a seed found under a mature tree, from winter collection to germination and early growth.
1. Winter: Finding Ginkgo Fruit Under the Tree
During winter, ginkgo trees drop their fruit on the ground.
These fruits are known for their strong and unpleasant smell, but inside is a valuable seed that can be grown into a beautiful tree.
- Ginkgo trees need cold winters
- The fruit falls as temperatures drop
- Seeds naturally overwinter on the ground
This cold period is essential for proper germination.
2. Cleaning the Ginkgo Seed
After collecting fallen fruits, I removed the smelly pulp and washed the inner seed thoroughly.
- Wear gloves (the pulp can irritate skin)
- Remove all fruit residue
- Rinse the inner nut until clean
Once cleaned, the seed looks like a small beige shell.
3. Soaking the Seed in Water
Before planting, I soaked the seed in water.
- Softens the shell
- Helps the seed absorb moisture
- Increases chance of germination
This soaking step mimics the natural winter thaw.
4. First Sign of Life: Tiny Root Emerging
After some time, the seed began to crack open.
A tiny white root appeared—like a small clam opening its shell.
This is the crucial moment when the ginkgo wakes up from winter dormancy
5. Planting the Germinated Seed
Once the root extended, I planted the seed in soil.
- Root faces downward
- Seed sits just below soil level
- Keep soil moist but not soggy
Ginkgo trees prefer simple, well-draining soil.
6. Spring: Ginkgo Sprout Appears
In spring, a small green sprout emerged from the soil.
- The stem lifts the seed coat
- First leaves unfold slowly
- Strong sunlight encourages growth
This early growth stage is slow but stable.
7. Summer: First True Leaves Appear
As temperatures rose, the true fan-shaped ginkgo leaves developed.
- Iconic split leaves
- Bright green color
- Growth increases with heat and full sun
Ginkgo is a sun-loving species, especially in summer.
8. Why Ginkgo Needs Four Seasons
Ginkgo trees have survived unchanged since the time of dinosaurs—
yes, herbivorous dinosaurs likely ate early ginkgo leaves.
Their growth cycle depends heavily on seasonal changes:
🌱 Spring – Sprouting and leaf growth
🌿 Summer – Fastest growth period
🍁 Autumn – Leaves turn bright yellow
❄ Winter – Essential dormancy for next year’s health
Without winter cold, ginkgo seeds may not germinate properly,
and the tree may grow weak the following year.
A Note About Eating Ginkgo Seeds
Ginkgo nuts are edible but must be eaten in moderation.
Adults should not consume more than 10 seeds per day,
as excessive intake can be harmful.
The plant itself is completely safe to grow.
Conclusion
Growing a ginkgo tree from seed is a seasonal journey—from smelly fallen fruit in winter to a beautiful, fan-leaved seedling in summer.
With proper cold exposure, watering, and sunlight, ginkgo trees grow slowly but reliably, rewarding you with brilliant yellow leaves every autumn.
