The Janed Gold Arborvitae (Thuja occidentalis ‘Janed Gold’) is an attractive evergreen cultivar known for its bright golden-yellow foliage. Its dense, scale-like leaves maintain their striking hue throughout the year, adding vibrant color to any landscape. It exhibits an upright, pyramidal to conical growth habit, making it a distinctive choice for various garden designs.
What to Expect from Janed Gold Arborvitae’s Growth
The Janed Gold Arborvitae is characterized by a moderate growth rate, typically adding between 6 to 12 inches to its height annually, with a proportional increase in width. A young plant can reach approximately 8 feet tall and 4 feet wide within its first ten years. This predictable development allows for accurate long-term landscape planning, as the plant will not rapidly outgrow its designated space. While environmental factors can introduce some variability, this moderate pace provides a reliable timeline for its establishment and progression. This growth habit ensures the plant maintains its naturally dense, upright, and often pyramidal form without requiring frequent, aggressive pruning.
Factors That Influence Growth Rate
The growth of Janed Gold Arborvitae is significantly shaped by several environmental elements.
Adequate sunlight exposure is a primary determinant; while the plant tolerates partial shade, its most vigorous growth and vibrant golden foliage develop when it receives at least six hours of direct sunlight daily. Insufficient light can result in slower growth and less dense foliage.
Soil conditions also play a substantial role in supporting healthy development. This arborvitae thrives in moist, well-drained soils, adapting to various types, including clay and sandy compositions. Optimal growth occurs in a soil pH range of 6.5 to 8.0. Poorly draining or consistently waterlogged soil can impede root function, leading to stunted growth.
Consistent moisture is another important factor influencing its growth. The Janed Gold Arborvitae requires regular watering, especially during establishment and dry periods. Prolonged drought causes stress, slowing growth and potentially increasing susceptibility to pests like spider mites.
The local climate and hardiness zone also dictate how well the plant will grow. Janed Gold Arborvitae is hardy in USDA Zones 5 through 8. Planting outside this suitable zone, or exposure to harsh, drying winter winds, can cause stress and inhibit its ability to grow optimally.
Availability of soil nutrients further impacts the plant’s vigor. While adaptable, it benefits from nutrient-rich environments, which fuel its cellular development and overall size increase. A lack of essential nutrients can restrict its growth potential.
How to Encourage Optimal Growth
To support the robust growth of your Janed Gold Arborvitae, begin with proper planting. Dig a hole twice the width of the root ball and ensure the top of the root ball sits slightly above ground level. After carefully placing the plant, backfill the hole and water thoroughly to eliminate air pockets, allowing for proper establishment.
Consistent moisture is equally important for vigorous development. Water deeply, especially during the plant’s initial two years and throughout dry periods, ensuring the soil remains moist but not waterlogged. Mulching around the base helps conserve soil moisture and regulate temperature.
Fertilization can further enhance growth. In early spring, before new growth emerges, apply a balanced, slow-release fertilizer. Following the product’s instructions is important to provide necessary nutrients without over-fertilizing, which can harm the plant.
Pruning requirements are minimal for this arborvitae. Light shaping or removal of dead or damaged branches in late winter or early spring can encourage denser foliage and maintain its form. Avoid excessive pruning into old wood, as it may not readily regenerate.
Maintaining the plant’s health also involves monitoring for common pests and diseases. Regularly inspecting the foliage for issues like spider mites or bagworms allows for early intervention, ensuring the plant remains vigorous and continues its steady growth.
Mature Size and Landscape Applications
The Janed Gold Arborvitae ultimately achieves a mature height ranging from 8 to 20 feet, with a spread of 3 to 5 feet. This range depends on growing conditions and the plant’s age, with the larger dimensions representing its potential over many decades. Its moderate growth rate contributes to a predictable final form, making it a reliable choice for various landscape designs.
Given its upright, pyramidal habit and dense golden foliage, this plant is well-suited for creating privacy screens or hedges. For a solid barrier, planting them approximately 3 feet apart is recommended. It also excels as a specimen plant, providing a vibrant focal point in a garden bed due to its striking color and refined shape. Additionally, its columnar form allows for effective use in foundation plantings or mixed borders, where it adds year-round structure and visual interest.
