Maidenhair tree (Ginkgo biloba)

Also known as: Kew Ginkgo

The Ginkgo biloba, also known as the maidenhair tree, is a living fossil with a history that stretches back approximately 270 million years, as evidenced by recognizable fossils. This species is among the earliest plants cultivated by humans. The ripe fruits emit an unpleasant odor, leading growers to often prefer planting male (non-fruiting) trees.

How to Water Maidenhair tree?

The Ginkgo biloba tree thrives best with a moderate amount of water, typically around 500 milliliters per watering. It is essential to ensure that the soil is well-drained, as Ginkgo prefers not to sit in waterlogged conditions. The goal is to keep the soil moist but not soggy, mimicking its natural setting. This amount ensures that the roots receive sufficient hydration without the risk of root rot.

What Is the Ideal Temperature Range for Maidenhair tree?

Ideal Temperature: 60 ~ 75℉

The ideal temperature range for cultivating Ginkgo biloba is between 60°F and 75°F. This range supports optimal growth, ensuring that the plant experiences balanced photosynthesis and metabolism. Ginkgo biloba thrives in mild climates where temperature fluctuations are minimal.

What Soil is Best for Maidenhair tree?

Soil type: Loam, Sandy soil, Sandy loam

Soil PH: 6.5 ~ 7.5

Ginkgo biloba thrives in well-drained soil to prevent root rot. This characteristic supports healthy root systems and ensures adequate nutrient uptake. The tree requires soil with moderate fertility, ensuring it receives enough nutrition for growth without being overwhelmed by excess nutrients, which could lead to nutrient burn. While Ginkgo biloba prefers well-drained soil, it also benefits from soil that retains moisture. Proper moisture levels help sustain growth during dry spells without causing waterlogging.

How to Fertilize Maidenhair tree?

Fertilizer type: Balanced

Ginkgo biloba, a resilient tree, requires balanced fertilization to thrive. During the growing season, apply a general-purpose fertilizer at half the recommended rate to avoid nutrient overload. This plant doesn't demand heavy feeding, making it a low-maintenance addition to any garden. More About Fertilizing Techniques→

How to Prune Maidenhair tree?

Pruning Time: Spring, Summer, Autumn, Winter

Begin by inspecting the tree for any dead, diseased, or damaged branches. These should be removed first to prevent disease spread and improve the overall aesthetic of the tree. Cut back to the nearest healthy branch or trunk. After removing the dead wood, focus on shaping the tree. Prune to maintain a balanced structure, removing any awkward branches that cross each other or grow inward. This helps in promoting an even, aesthetically pleasing canopy. While shaping, keep the interior of the canopy open to allow for air and light penetration. This reduces the risk of diseases and promotes healthy foliage. Removing excess branches from the center encourages a healthy, open structure. More About Pruning Techniques→

How to Propagate Maidenhair tree plant?

Propagate Time: Late spring,Early summer

Collect seeds from mature Ginkgo biloba in autumn. Clean the seeds of any flesh and let them dry. It's crucial to stratify the seeds in a refrigerator for about three months before planting to break dormancy, which enhances germination rates.

Sow the stratified seeds in pots with the sterile potting mix in late spring. Bury them at a depth equal to twice the diameter of the seeds. Water the mix to keep it consistently moist but not waterlogged.

Place the pots in a warm, sunny location. Ensure adequate sunlight as ginkgo seedlings require it for healthy growth. Water regularly but avoid overwatering, which can cause roots to decay. Thin out weaker seedlings to give stronger ones more space to thrive.

How to Repot Maidenhair tree plant?

Repotting frequency: Every 3-5 years

Ginkgo biloba needs repotting when the roots start circling the pot or emerging from drainage holes. Typically, observing slow growth or yellowing leaves can also signal the need for a new pot. Ideal repotting periods are typically in early spring or autumn to minimize plant stress.

Select a pot that is 2 to 3 inches larger in diameter than the current one, with adequate drainage holes. A pot of this size will allow the roots to spread and grow without becoming waterlogged. Materials like terracotta can help with moisture regulation.

Choose a well-draining loamy soil mix. This ensures that the Ginkgo biloba receives adequate moisture without waterlogging. Adding a bit of compost can enrich the soil, offering essential nutrients that promote healthy growth.
