Due to its adaptability and rapid development, the Spartan Juniper is frequently utilized to create effective year-round boundary trees or can serve beautifully as a stand-alone specimen tree that enhances the aesthetic of any outdoor space.

Height and Width of Spartan Juniper Trees

In terms of height and spread, the Spartan Juniper can attain impressive dimensions, with mature specimens often reaching heights of up to 20 feet and expanding to about 5 feet in width. 

However, it is important to note that the ultimate size of the tree may vary based on several factors, including the specific location where it is planted and the level of care it receives during its growth. Factors such as soil quality, sunlight exposure, and watering practices all contribute to the overall health and size of this conifer.

As an exceptional evergreen, the Spartan Juniper develops into a striking tree characterized by its elegant structure and rich, dark green foliage. Its densely branched formation contributes to a visually appealing upright silhouette, making it an ideal candidate for formal landscaping designs.

The combination of its fast growth rate and aesthetic appeal allows the Spartan Juniper to serve as a functional yet decorative element in gardens and public spaces alike, enhancing the overall landscape while providing benefits such as privacy and windbreaks. They are fast growers and can grow up to 2 ft. per year if the conditions are right.

Problems with Spartan Junipers

By far the biggest problem is spider mites (Tetranychus urticae). These little insects are hard to see with the naked eye and thrive in dry hot conditions. You can spot these insects by the light brown webbing they produce in late spring or early summer. You can use spider mite insecticide to control these insects.

One easy and organic way to remove these mites is by watering these trees with a strong stream of water. Spray it from the top down to the bottom. Do this at least once per week during the growing seasons.
