Growth Stages

1

Seedling

6-12 months

Young ginkgo with small, soft green fan-shaped leaves; weak stem structure

Provide shelter from strong winds; keep soil consistently moist; protect from harsh sun if grown indoors initially

2

Establishment

2-4 years

Young tree developing stronger trunk and branching structure; gradual increase in leaf size

Water regularly and deeply; apply 2-3 inches of mulch around base; stake if necessary for wind protection; prune only to remove crossing branches

3

Growth Phase

5-15 years

Tree developing its characteristic form; fan-shaped leaves fully formed; increasing branch density

Continue regular watering until fully established; fertilize annually with balanced slow-release fertilizer in spring; maintain consistent pruning shape if desired

4

Maturity

Ongoing (20+ years)

Full-sized tree with dense canopy and characteristic shape; reaching 30-50+ feet tall; spectacular golden fall foliage

Minimal watering needed; maintain shape with light pruning; remove dead or diseased branches; fertilize as needed for vigor

5

Senescence

Centuries to millennia

Ancient tree with thick trunk, spreading crown, and potential decline in vigor

Monitor for disease and pest pressure; remove dead wood promptly; avoid compacting soil around root zone; provide structural support if needed

Harvest Tips

Ginkgo trees produce fruit (seeds) in female trees, which have an extremely unpleasant odor. Harvest fruit in fall when it falls naturally; wear gloves to handle. Seeds are used in traditional Chinese medicine and culinary applications. Male cultivars are preferred in landscaping to avoid foul-smelling fruit.

Fun Facts
