There may be no tree that can grow naturally in so many different types of climates in the Northern hemisphere than the juniper. With roughly 60 different species available -- ranging from low-growing groundcovers to shrubs to full-size trees that can grow as high as feet, species from this member of the cypress family can grow in arctic climates, as well as deserts.
Juniper tree varieties come in a variety of shades -- from deep to silvery greens and then shades of blue, bronze, and even gold.
As a coniferous evergreen, juniper leaves start out rough, prickly, and needle-like, but soften as they mature into flattened, scale-like foliage. Depending on the species you choose, junipers can have an upright, spreading, or weeping habit, and can range in size from 6 inches to feet tall and a spread range from 1 to 25 feet.
Tall varieties with thick foliage can make great windbreaks. Eastern red cedar Juniperus virginiana - Found in eastern North America in zones 2 to 9, red cedar is an especially fragrant form of juniper with dark blue-green foliage and gray to reddish-brown bark. It can grow 30 to 40 feet tall and enjoys full sun. While it tolerates moisture well, it does not like soggy soil. California junipe r - This favorite for creating wildlife habitats and drought-tolerant landscapes in the Southwest U.
This juniper is tolerant of alkaline soils and growing 10 to 15 feet tall in zones 8 to 10 has also been used in bonsai. Common juniper - This common sun-loving shrub is widely distributed on rocky soils throughout the Northern Hemisphere. Working well in both acidic and alkaline soils, this juniper is one of the rare ones that has needle-like leaves rather than scales. Growing in zones 3 to 8, it matures to around 15 feet tall, sometimes reaching 30 feet.
Creeping juniper - This juniper works well as a groundcover, with many varieties having yellow foliage and producing blue-white berries. In full sun in zones 3 to 9 is where this juniper grows.
Greek juniper - Growing in zones 5 to 9, this hardy tree can reach 20 to 65 feet tall in full sun. Sometimes growing massive trunks -- up to 6 feet diameter -- the Greek juniper has gray-green foliage and purple-blue berries. Then, carefully read the specifics about planting and caring for Juniper Trees in the proceeding sections. The Tree Center offers carefully chosen Junipers, which will ship quickly to most locations throughout the United States.
This species of Juniper offers blue-tinted foliage, which can grow quickly, making it ideal for privacy screens and perimeter barriers. Be sure to buy from tree specialists, such as those at The Tree Center, as the initial growth of the Juniper Tree prior to planting will impact future growth.
Water : Water immediately after planting and once per week for the first twelve months, unless it rains. When to Plant : Spring is best, though Junipers can also be planted in late fall with proper mulching. Juniper Trees are hardy and adaptable trees, but they still have their preferences for water needs, soil types, and location areas.
Depending on the species of Juniper Tree planted, different locations may be beneficial. For example, taller species, such as the Hollywood Juniper or the Spartan Juniper, can reach upwards of 15 feet tall.
These should be planted far away from foundations and fences; on the other hand, the Juniper Wichita Blue can reach 30 feet, but is often pruned to less than 10 feet, enabling it to remain a tall hedge acting as a privacy screen. These smaller shrubs do well when planted along property lines, and the Juniper Wichita Blue can be planted closer to homes.
Once the location has been identified, the next step is to dig a hole. When planting any kind of tree, a wide hole is needed. Do not worry about the depth of the hole. This is because the tree will settle over time.
So, make sure the top of the root ball is visible once in the hole. The next part is best done with two people; set the tree in the hole so it stands vertically.
Then, begin backfilling the hole with soil. Water immediately after planting and gently compact the soil around the plant with feet and hands. If using mulch, begin mulching with 3 to 4 inches of mulch around the base of the tree. Juniper Trees do not do well with excessive watering , which is, in part, why the soil consistency matters significantly. Identifying the soil type in which the Juniper Tree will be planted is essential to future growing success.
The soil will fall into one of three categories. Clay soils are made of small particles. When wet, the soil clumps together with ease, often making it difficult to separate the soil into its component pieces again. Clay soils are usually red-tinted, and though useful in pottery, are detrimental to water-draining properly through the soil. Silt or sand soils are similar. The particles are larger than in clay, though equally poor for water transference. Loam soils are the best, especially for Juniper Trees.
Loam soil is characterized by a variety of granular sizes. This variety not only allows for diverse nutrient offerings, but also for excellent water drainage and oxygen availability. Whatever soil the Juniper Tree is planted in, the tree can be successful with proper care and attention. The difference is that in loamy soils, less direct intervention from the planter will be needed. Juniper Trees grow well in areas in which droughts are frequent , though during a sustained water absence, some minimal watering by the landscaper may be necessary.
Juniper Trees can be drought tolerant. Water the Juniper Tree immediately after planting and once per week for the first 12 months at least after planting unless it rains. Water with two to three gallons of water to a depth of 30 inches. It can grow to 20 feet, with widths of only 2 or 3 feet.
This is a fast growing juniper that has fine, feathery blue foliage. It is hardy in USDA zones 2 through The healthier the tree, the better and faster it will grow. In general, junipers thrive in full sun to partial shade, depending on the species, and with regular watering. They can adapt to all soils, except those that are heavy and wet, so do not plant a juniper tree next to a source of water, such as a stream or lawn sprinkler.
In general, these trees prefer soil that is on the dry side, so err on the caution of under-watering your junipers. By April Sanders Updated December 14, Related Articles.
