The Sky High Juniper, also known as Juniperus scopulorum ‘Sky High’, is a popular choice for landscaping due to its narrow columnar growth and bluish green foliage. As an expert in gardening and landscaping, I can provide you with a detailed answer regarding the growth rate of this particular juniper variety.
The Sky High Juniper is characterized by its slow growth rate, which is ideal for those looking for a tree that won’t quickly outgrow its space. In general, it takes about 10 to 15 years for this juniper to reach a height of around 15 feet. This means that on average, it will grow at a rate of approximately 1 to 1.5 feet per year during its early years.
However, it is important to note that the growth rate may vary depending on various factors such as climate, soil conditions, and care provided. In optimal conditions, the Sky High Juniper may grow slightly faster, while in less ideal conditions, its growth rate may be slower.
In my personal experience, I have found that the Sky High Juniper tends to establish itself relatively quickly during the first few years after planting. During this initial period, it focuses on developing a strong root system, which is crucial for its long-term growth and stability. Once the root system is well-established, the tree can then start putting more energy into its above-ground growth.
It is also worth mentioning that as the Sky High Juniper matures and reaches its maximum height, which can be up to 15 feet in about 30 years, it may start to experience some bending of its lateral branches. This bending can sometimes result in the branches touching the ground, which can affect the overall form and aesthetics of the tree.
To prevent this bending and maintain the desired columnar shape, it is important to provide proper support and pruning as needed. Regular pruning can help to remove any excessively long or drooping branches, ensuring that the tree maintains its desired form.
The Sky High Juniper is a slow-growing tree, averaging about 1 to 1.5 feet of growth per year during its early years. However, the growth rate can vary depending on environmental factors. Regular pruning and support may be necessary to maintain its desired form as it matures.
