About this plant
Ginkgo biloba, often called the maidenhair tree, is a unique tree known for its fan-shaped leaves that turn bright yellow in autumn. It is a living fossil, meaning it has existed for millions of years with little change. Ginkgo is popular in parks and streets for its beauty and resilience. It is also used in traditional medicine and supplements.

Watering. Water young trees regularly to keep soil moist but not waterlogged. Mature trees tolerate drought and need less frequent watering.
Fertilizing. Fertilize young trees in early spring with a balanced slow-release fertilizer. Mature trees usually do not need much fertilizing unless soil is poor.
Ginkgo biloba is a tough tree that grows well in many conditions. It prefers full sun and well-drained soil. It is resistant to pests and diseases but needs space to grow as it can become quite large. Regular watering is needed when young, but mature trees tolerate drought well.

Toxicity & Safety
Ginkgo is generally safe but seeds from female trees can cause skin irritation and are mildly toxic if eaten in large amounts. Keep away from children and pets.
Allergy information
Ginkgo biloba pollen can cause allergic reactions in some people, especially during its pollination season. The main trigger is the airborne pollen, which may cause sneezing, runny nose, or itchy eyes. To reduce exposure, avoid being near male trees when they release pollen, and keep windows closed during this time if sensitive.
Common problems
Young trees may suffer from overwatering or poor drainage leading to root rot. In urban areas, pollution can stress the tree. Occasionally, pests like aphids may appear but are usually not serious.
Uses
Ginkgo is mainly used as an ornamental tree in parks and streets. It is also valued for its medicinal leaves and supplements.
Notes
Male trees are preferred for planting because female trees produce seeds with a strong odor. Prune in late winter to shape or remove dead branches. Repotting is rarely needed for outdoor trees.
