The ‘Ginkgo biloba ‘Everton Broom” is a distinct cultivar prized for its unique, compact form and vibrant seasonal color. This dwarf ginkgo offers gardeners an alternative to the larger species, fitting well into diverse landscape designs. Its slow growth rate and adaptability make it a manageable choice for many settings.
Understanding ‘Everton Broom’ Ginkgo
‘Everton Broom’ is a specific cultivar of Ginkgo biloba, originating from a “witch’s broom” mutation discovered in Everton, UK. This genetic anomaly results in a dense, compact, and often spherical or globose growth habit. The plant typically reaches about 30 inches tall and 36 inches wide.
Its growth rate is slow, usually around 2 to 4 inches per year. The foliage consists of characteristic fan-shaped leaves, which are bright green and noticeably smaller than those of the species. In autumn, these leaves transform into a brilliant golden yellow before they are shed. The branches often grow at a distinct 45-degree angle.
Essential Growing Conditions
Light Needs
‘Everton Broom’ ginkgo thrives in full sun exposure. Ample sunlight promotes robust growth and enhances the intensity of its golden fall color. While it prefers full sun, it can tolerate partial shade, though growth may be slower and autumn leaf coloration less vibrant.
Soil Requirements
This ginkgo cultivar is adaptable to a wide range of soil types, including clay, loam, and sandy soils. It performs best in average, well-drained soil, as it does not tolerate standing water or soggy roots. The plant is tolerant of compacted soil and various pH levels, from slightly acidic to alkaline.
Watering Practices
Upon planting, ‘Everton Broom’ requires regular watering to help establish its root system. During the first few months, it benefits from deep watering several times a week, ensuring the roots receive adequate moisture without the soil becoming waterlogged. Once established, the ginkgo becomes quite drought-tolerant and needs minimal supplemental water. Established trees do well when the top three to six inches of soil are allowed to dry out between waterings, and deep, infrequent watering is preferable to shallow, frequent applications.
Fertilization Guide
‘Everton Broom’ ginkgo generally has low fertilization needs. Young trees may benefit from an annual application of a balanced, slow-release fertilizer in the spring to encourage new growth. Applying organic compost in the spring can also provide adequate nutrients. Mature trees typically do not require additional feeding unless the soil is particularly poor, as excessive fertilization can lead to vigorous but weaker growth.
Pruning and Maintaining Shape
‘Everton Broom’ ginkgo generally requires minimal pruning due to its naturally globose growth habit. Its dense, broom-like form is typically maintained without extensive intervention. Pruning is primarily done to remove any dead, damaged, or crossing branches during the tree’s dormant season. Trimming can also manage its size, particularly if grown in a container, but should be done sparingly to preserve its natural contour. Heavy pruning is not typically necessary.
Ideal Landscaping Uses
The compact size of ‘Everton Broom’ ginkgo makes it suitable for a variety of landscape applications. Its dwarf nature allows it to be incorporated into small gardens, rock gardens, and urban spaces where larger trees would be unsuitable. It functions well as a specimen plant, drawing attention with its shape and golden fall color.
This cultivar also thrives in containers, making it a versatile choice for patios, balconies, or other limited spaces. It also lends itself to the art of bonsai. ‘Everton Broom’ provides a visual element as a focal point or as part of a border planting.
Addressing Common Concerns
‘Everton Broom’ ginkgo is known for its general hardiness and resistance to most pests and diseases. Its slow growth rate means it will take many years to reach its mature size, which can be beneficial for small spaces.
While ginkgos are largely resilient, yellowing leaves can indicate stress, often related to improper watering. Overwatering or insufficient drainage can lead to root problems, while underwatering, particularly for newly planted trees, can cause stress. Transplant shock can also manifest as leaf discoloration or wilting after planting. Ensuring proper soil drainage and consistent, appropriate watering, especially during establishment, helps mitigate these concerns.
