Goldspire Ginkgo Tree (Ginkgo biloba ‘Goldspire’)

The hearty Ginkgo is a marvel of nature’s endurance, tracing its roots back over 270 million years in China. Remarkably, a single Ginkgo tree can thrive for up to 3,000 years. As autumn approaches, the Ginkgo emerges among deciduous trees, transforming its distinct fan-shaped leaves from green to a radiant yellow, heralding the season earlier than most.

While its stature can be imposing, the Ginkgo is versatile, making it a suitable choice for various places. Its non-invasive roots mean it can flourish in confined areas, and its resilience to pollution, drought, salt, and pests makes it an excellent street tree. Requiring minimal care once established, the tree is both ornamental and functional, providing shade and aesthetic appeal.

The Goldspire variant of the Ginkgo, known scientifically as Ginkgo biloba ‘Goldspire,’ is particularly noteworthy. Unlike its larger counterparts, the Goldspire maintains a compact size, reaching heights of about 15 feet, ensuring it remains manageable for most gardens while still showcasing the tree’s signature vibrant foliage.

Appearance

Ginkgo trees, while known for their beauty, are sometimes regarded as messy. This perception largely stems from the female Ginkgo, which sheds copious seeds carrying an off-putting aroma. In contrast, male Ginkgo trees are less troublesome, as they don’t bear fruit or emit any unpleasant smells.

The typical Ginkgo tree stands as a testament to grandeur, often soaring to over 80 feet when fully grown. Yet, the Goldspire variety is an exception to this towering stature. More compact, the Goldspire reaches an approximate height of 15 feet and spreads to a width of around 10 feet, making it a more modest presence in gardens and landscapes.

Growing and Care Conditions

Goldspire Ginkgo Tree The Goldspire Ginkgo tree is a versatile addition suitable for varied landscapes. Notably hardy, it can endure temperatures as chilling as -20 degrees and withstand both heat and drought. Ideally grown within USDA zones 4-9, the Goldspire thrives in almost any soil.

Its compact stature, reaching 15 feet in height and spanning up to 10 feet in width, makes it apt for urban streetscapes, parking areas, or residential gardens. The tree’s leaves transition from a summer green to a striking golden hue in the fall. Furthermore, being a male variety, it sidesteps the pitfalls of unpleasant odors and tedious cleanup associated with female Ginkgo trees.

Planting

While the Goldspire Ginkgo relishes full sun, it can adapt to partial shade, especially in hotter regions. For optimal growth and color in cooler areas, six or more hours of sunlight are ideal. The tree thrives best in well-draining soil but can also handle higher moisture levels than some other varieties.

Salinity, both airborne and in the soil, doesn’t deter its growth. To plant, dig a hole wider than the tree’s root ball and slightly shallower. Position the tree straight within the hole, backfilling with a mix of native soil and organic matter. An initial dose of water and nutrient-rich compost sets it on the path to thrive.

Light

Sunlight, be it full or partial, benefits this tree.

Watering

To foster a robust root system, young Goldspire ginkgo needs consistent watering. In warmer climates, a bi-weekly schedule during summer and every 3-4 days in cooler weather is recommended. It’s crucial not to over-saturate the soil; ensure the upper 1-2 inches dry out between waterings. Once mature, the tree primarily needs hydration during droughts. Mulching around the base aids in water conservation.

Fertilizer

In its early growth phases, a spring application of a balanced slow-release fertilizer, like a 10-5-5 or 10-10-10 blend, can enhance the tree’s vitality. However, as Ginkgos aren’t particularly nutrient-hungry, over-fertilization should be avoided.

Pruning

Once it has settled, the Goldspire requires minimal pruning to retain its shape. In its initial 3-4 years, a light shear in spring assists in cultivating dense branching. Pruning is best undertaken during dormancy, between late fall and early spring. Focus on removing any declining branches, and refrain from trimming the central part.

Pests and Diseases

While the Goldspire Ginkgo is fairly resilient, it can occasionally succumb to nematodes or root rot, the latter often stemming from overwatering.

Pollination

Wind typically facilitates the transfer of pollen between male and female Ginkgo trees. It’s worth noting that Ginkgos can take several years to reach reproductive maturity. As Goldspire is a male variety, it remains seedless and thus, free from the offensive odor associated with female Ginkgo seeds.

Maintenance

For the Ginkgo tree to flourish, it’s essential to ensure it’s planted in suitable conditions. While spring and fall present the best planting windows, avoiding extreme temperatures allows for flexibility in planting seasons based on the specific zone.

These trees prefer full to partial sunlight and thrive in well-draining soil. Remarkably adaptive, the Ginkgo tree can adjust to various soil types, including clay, provided it remains unsaturated. It also showcases resilience to diverse pH levels.

Mulching proves beneficial, especially in temperature extremes; it maintains root moisture during heat and offers cold protection. However, a mulch barrier of 2-3 inches is recommended, ensuring it doesn’t directly contact the trunk to minimize pest and disease risks. Once planted, water the Ginkgo deeply twice a week until it establishes and becomes drought-tolerant.

A slow-release fertilizer applied during planting or in early spring enhances growth. While Ginkgos typically don’t demand pruning, it can be done during dormancy to remove undesirable branches or shape the tree. Notably, their resistance to pollution, salt, pests, and diseases makes them exceptional choices for urban environments.

Root rot poses a rare but genuine threat to the Goldspire ginkgo variety. Prioritizing a planting location with excellent soil drainage minimizes this risk. The tree’s versatile nature means it can stand alone as a specimen or be part of a hedge, amplifying its landscaping appeal.

Uses

The Ginkgo tree is not just a tree; it’s a statement. Standing tall at 60 feet and spreading around 40 feet, it serves as a majestic shade provider. Whether placed individually or in clusters of up to three in outdoor spaces, or aligned in rows for driveway linings or backyard borders, it transforms landscapes.

When considering a shaded pathway or hedge, allocate at least 15 feet of space between each tree, guaranteeing optimal growth and a lasting impression. This tree not only beautifies spaces but also offers cooling shade, contributing to energy efficiency.
