How Often to Water a Blue Point Juniper

Identification

• The “Blue Point” juniper cultivar grows to roughly 12 feet tall and 8 feet wide, but can sometimes reach 15 feet tall. It grows in a naturally conical form, tapering to a point at the top. There are many cultivars of Chinese juniper (Juniperus chinensis), and even more that have been lumped erroneously under this name. “Blue Point,” however, is a true cultivar of Chinese juniper. Winter hardy in U.S. Department of Agriculture plant hardiness zones 4 through 9, it does well in a wide range of climates and planting sites.

Water Needs

• “Blue Point” juniper prefers slightly moist, sandy soil that drains quickly. It does not like to stand in water or be overwatered. However, although it is drought tolerant, you should not deprive it of water at any time until it is well established, which takes about three years. During the first three years, water it as regularly as needed to keep soil consistently moist, and add a 2- to 3-inch layer of mulch to aid in moisture retention. Water deeply and infrequently, about every five to seven days in hot weather. After that, it will be quite drought tolerant and won’t need more water than what it gets from rainfall.

Culture

• Chinese juniper cultivars such as “Blue Point” are generally low-maintenance, and are noted for attaining the desired shape on their own. Choose the correct cultivar for your yard to cut down on the need for pruning. The plant will grow in both sun and shade, but develops dense branch structures and looks best in full sun. In very hot, dry climates, however, some light shade helps. When watering the tree, keep foliage dry. When planting, try not to crowd it -- this juniper likes some room around the base.

Garden Uses

• “Blue Point” juniper works well as a specimen plant -- its tall pyramidal form drawing the eye. It also works well as a hedge plant. If you use it for hedges, plant the trees at least 8 feet apart. Grown in a line at the edge of a garden or property, it provides both privacy and a good windbreak. Its blue-green, scale-like foliage also gives your yard winter interest. Birds may shelter inside its dense branches in the winter.
