- Water
Ginkgo biloba, commonly known as the maidenhair tree, should be watered deeply and thoroughly, allowing the soil to dry slightly between waterings. In general, this means providing the tree with about 1 to 2 gallons of water every two weeks during the growing season, although this can vary depending on climate and soil conditions. It is important to avoid over-watering, as the maidenhair tree does not tolerate excessively wet soil. Younger trees will require more frequent watering to establish a strong root system, while mature trees can be watered less often.
- Light
Maidenhair trees are best suited for areas that receive full sun to partial shade. They can tolerate a variety of lighting conditions but thrive with exposure to at least 6 hours of direct sunlight each day. Planting a maidenhair tree in a location that receives morning sunlight with some afternoon shade is often ideal, especially in hotter climates.
- Temperature
Maidenhair trees are highly adaptable and can withstand a wide temperature range. Ginkgo biloba can survive in temperatures as low as -30 to -50 degrees Fahrenheit during dormancy in the winter and can tolerate the summer heat up to 100 degrees Fahrenheit. Ideal growing temperatures for the maidenhair tree range from 65 to 75 degrees Fahrenheit, where it can flourish and grow.
- Pruning
Pruning the maidenhair tree is typically done to remove any dead or broken branches and to maintain its natural, attractive shape. Pruning should be performed in late winter or early spring before the tree begins its active growth. It doesn't require heavy pruning, and it is usually sufficient to prune it every few years. The best time for pruning is when the tree is dormant to minimize sap loss and stress to the tree.
- Cleaning
As needed
- Soil
The Ginkgo or Maidenhair tree thrives in well-draining, sandy or loamy soil with a pH of 5.0 to 8.0. A good mix would be equal parts garden soil, peat moss, and perlite to ensure proper drainage and aeration.
- Repotting
Ginkgo trees are slow growers and do not need to be repotted frequently. Young trees can be repotted every 2-3 years, but mature trees might only need repotting every 5 years or more, depending on the pot size.
- Humidity & Misting
Ginkgo trees are adaptable and can tolerate a wide range of humidity levels, but they typically prefer normal to lower humidity environments, as they are drought-tolerant once established.
- Suitable locations
Indoor
Place in bright light, minimal watering.
Outdoor
Sunny spot, well-drained soil, tolerates cold.
Hardiness zone
3-9 USDA
- Life cycle
Ginkgo biloba, commonly known as the Maidenhair Tree, is a dioecious plant, meaning it has separate male and female individuals. The life cycle begins with seed germination, which can be erratic, with some seeds requiring a period of stratification to break dormancy. Once germinated, the seedling grows into a juvenile tree, characterized by a straight stem and symmetrical branches. With maturity, over many years, the tree develops distinctive fan-shaped leaves and, if female, produces ovulate cones with ovules that, after pollination by the wind-carried pollen from the male trees, mature into seeds with a fleshy outer layer. Male Ginkgo trees produce catkin-like pollen cones that release pollen into the air. The Maidenhair Tree can live for a very long time, with some specimens known to be over 1,000 years old, continuing the cycle by producing new seeds each year.
- Propogation
Propogation time
Early Spring
Ginkgo biloba, commonly known as the ginkgo or maidenhair tree, is most commonly propagated through seeds. The optimal time for seed propagation is in the autumn right after the seeds have ripened. Mature ginkgo seeds have a fleshy outer layer that needs to be removed before planting due to its possible inhibitory effects on germination. Once the seeds are cleaned, they can be stratified—a process that simulates winter conditions. Stratification involves mixing the seeds with slightly moist sand and storing them at cold temperatures, usually between 33 to 41 degrees Fahrenheit (1 to 5 degrees Celsius), for about 60 to 90 days. After stratification, the seeds can be sown in well-draining soil in a sunny location. It's important to note that ginkgos have a long juvenile period and it may take many years for a seed-grown tree to reach maturity and produce its own seeds.
